HALO 2000 SERIES and HALO 3000 SERIES radar systems consist of a pedestal, antenna, RI-50 radar interface module and connection cables. A supplied Ethernet network cable connects the RI- 50 radar interface module to the navigation Ethernet network. ¼ Notes:

• HALO 2000 SERIES and HALO 3000 SERIES radar systems are available with antennas in three sizes: 3 ft, 4 ft and 6 ft.
• At the time of release, HALO 2000 SERIES and HALO 3000 SERIES radars work with Simrad® GO XSR, GO XSE (9/12), NSSevo3, NSSevo3S, NSOevo3, NSOevo3S and NSOevo3S MPU systems. They also work with Simrad® R2009 and R3016 radar control units.

Warnings

⚠ Use the radar at your own risk. Your radar is designed as a navigation aid. Always compare the navigation information received from your radar with data from other navigation aids and sources. When a conflict arises between the navigation data from your radar and data from other navigation aids, make sure you resolve the conflict before proceeding with navigation. A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN NAVIGATION INFORMATION. International Regulations for Preventing Collisions at Sea mandate that when radar is on a vessel, the radar must be used at all times, regardless of weather conditions or visibility. Numerous court decisions have ruled that the radar must be used, and the radar operator must know all operational aspects of radar performance. Otherwise, they will face a greater risk of liability if an accident occurs.
⚠ High current, stored and microwave energy hazard. Technicians must exercise extreme care when working with the unit. ALWAYS disconnect from the power source before removing the pedestal side covers. Some capacitors may take several minutes to discharge, even after switching off the radar. Before touching any high-voltage components, ground them with a clip lead.
⚠ The radar’s blue 4-level static accent pedestal lighting may not be approved for use in your boating location. Please check your local boating regulations before turning the blue accent lights ON.
⚠ The microwave energy radiated by a radar antenna is harmful to humans, especially the eyes. NEVER look directly into an open waveguide or into the path of radiation from an enclosed antenna. Disconnect from the power source or use the service mode switch on the back of the pedestal whenever you need to work on the antenna or other equipment in the beam of the radar.

TOOLS REQUIRED

INSTALLATION

INSTALLATION GUIDELINES

⚠ Warning: A radar should only be installed by a qualified marine technician, as improper installation poses risks to the installer, the public, and to the safety of the vessel.
⚠ Warning: Before starting the installation or any maintenance on a HALO 2000 SERIES or HALO 3000 SERIES radar, make sure the service mode switch at the back of the pedestal is set to 0 (power supply disabled).

There is a transmit interlock that prevents radar transmissions if the antenna is not rotating. However, a high voltage remains for a period of time after the system is turned off. If you are not familiar with this type of electronics, consult a trained service or installation technician before trying to service any part of the equipment.

Installation includes:

• hardware mounting
• electrical wiring
• configuring the display or network system to work with the radar
• adjusting the radar for proper performance. The radar’s ability to detect targets depends greatly on its location. The ideal location is high above the vessel’s keel line where there are no obstacles. A higher installation location improves the radar’s ranging distance, but it also increases the range around the vessel where targets cannot be detected and increases sea clutter pick up. When you are deciding on the location, consider the following:
• The length of the 20 m (66 ft) interconnection cable supplied with the radar is usually sufficient. A longer 30 m (98 ft) cable is available. 30 m (98 ft) is the longest the cable that can be used.
• If the roof of the wheelhouse is the highest existing location, consider installing a radar mast or tower on which you can mount the radar.
• If you install the radar on the mast, position it on the forward side so there is a clear view to the front of the vessel.
• It is preferable to install the antenna parallel to the line of the keel.

What not to do

• Do not install the radar too high, where its weight may compromise the stability of the vessel and degrade the radar picture over short ranges.
• Do not install the radar close to lamps or exhaust outlets. Heat, soot, and smoke emissions may degrade radar performance or cause a breakdown.
• Do not install the radar where a large obstruction (such as an exhaust stack) is at the same level as the beam. The obstruction is likely to generate false echoes and/or shadow zones. If there is no alternative location, use the radar’s sector blanking setting on your multi-function display.
• Do not install the radar close to the antennas of other equipment, such as direction finders, VHF antennas and GPS equipment, as it may cause interference.
• Do not install the radar where may be subjected to strong vibrations that could degrade its performance.
• Do not install the radar close to halyards or flags because the wind could wrap these around the antenna and jam it.

Compass safe distance

Do not install your HALO radar or RI-50 inside of the recommended safe distances of navigational instruments like the magnetic compass and chronometer.

Multi-radar installations

Do not install your HALO 2000 SERIES or HALO 3000 SERIES radar on the same horizontal beam plane as any other radar. Separate them vertically by at least 2 m (6.6 ft).

SERIES radar

Note: Possible interference can be reduced using the radar’s sector blanking setting on your multifunction display.

Powerboat installations

If possible, make sure the mounting location gives your radar a clear view all around the vessel.

If you install your HALO radar on a power boat with a steep planing angle, it is recommended you tilt the radar angle down at the front

Note: Optional 4° base wedges are available from third-party suppliers.

Considerations for Roof Mounting

When deciding a suitable mounting location for your HALO radar, be aware that the vertical radar beam extends to 25° either side of horizontal, with 50% of the emitted energy projecting in a beam 12.5° either side of horizontal. If the radar beam cannot clear the roof line, this decreases the performance of the radar. Depending on the size of the hard top of the vessel, we recommend you elevate the antenna to ensure the radar beams clear the roof line.

Possible performance loss

If you mount your HALO radar directly on to a large hard top, the radar’s performance could suffer as the emitted energy is either reflected or absorbed by the hard top.

Good performance

Raising the radar off the hard top allows most of the radar beam to clear the hard top.

Best performance

For best performance, the radar should be positioned to allow the full beam to clear the superstructure of the vessel.

Note: If the mounting surface is made of metal, you must elevate the radar so the beam has complete clearance, otherwise its performance will be severely impaired.

To calculate the antenna height for best performance, first measure the distance (A) from the installation location of the radar to the furthest forward corner of your vessel’s hard top.

For every increase of 200 mm (7.9”) of hard top distance over 1.8 m (6.0”), increase the height of the antenna by 46 mm (1.8”).

HARDWARE MOUNTING

Install the RI-50 radar interface module

Install the RI-50 in a dry location away from spray, rain, drips, condensation or excessive heat. The mounting position should be easily accessible. Always mount the RI-50 vertically, with the cable entry points facing downwards. This helps with cooling and helps prevent any water from entering the cable grommets. Ensure there is enough unobstructed space above and below the RI-50 to ensure it cools adequately and the ambient temperature does not exceed 55°C (131°F). If overheating is a concern, consider additional ventilation, such as a vent or extraction fan. ⚠ Warning: Inadequate ventilation and subsequent overheating of the unit may cause unreliable operation and reduced service life. Exposing the equipment to conditions that exceed the specifications could invalidate your warranty.
The RI-50 must be located where it can easily connect to the vessel’s ground connection, the pedestal interconnection cable and the power cable. Use fasteners suited to the mounting surface material. If you are using the supplied self-tapping screws with a soft material like plywood, use a 2.3 mm to 2.8 mm (3/32”) drill bit. For hard materials like GRP, acrylic and hardwoods, use a 2.9 mm (7/64”) drill bit. If the material is too thin for the selftapping screws, reinforce it or use machine screws, nuts and washers. Use only 304 or 316 stainless steel fasteners. Mark the screw locations using RI-50 box as a template, and drill pilot holes.

Run the interconnection cable
The interconnection cable is 10.5 mm (0.4”) in diameter. The 14-pin connector end of the cable connects to the pedestal. The RJ45 connector connects to the RI-50 radar interface module.

1. Drill a 14 mm hole to pass the RJ45 connector from the pedestal to the RI-50, or a 24 mm (0.95”) hole to pass the 14-pin connector from the RI-50 to the pedestal.
2. To protect the connectors, especially the RJ45 connector, when pulling the cable through the vessel, connect a mouse line to the outer jacket of the interconnection cable so the strain of pulling is transferred to the strong outer jacket.
3. If there is enough clearance, use a small cable tie to secure the mouse line to the outer jacket.
4. Tape the wires and the RJ45 connector to the mouse line so they do not get caught and bend backwards.

• Carefully pull the interconnection cable through the vessel so it runs between the RI-50 radar interface module and your chosen pedestal location.

Install the pedestal

⚠ Warning: Leave the waveguide protection cap on the pedestal while you mount it to your vessel. You should only remove the cap just before you fit the antenna to the pedestal.

Bolts and washers

The eight hex head bolts supplied are suitable for surfaces up to 25 mm (1”) in thickness.

• Use the 4 x M12 x 35 mm (1.4”) for a surface thickness from 5 mm (0.2”) up to 13 mm (0.5”).
• Use the 4 x M12 x 50 mm (2.0”) for a surface thickness from 13 mm (0.5”) up to 25 mm (1”).

If using longer bolts, ensure they are marine-grade stainless steel and allow for a minimum of 12 mm (0.3”) and maximum of 20 mm (0.7”) of thread engagement in base of the pedestal. Use a flat washer and a spring washer for each bolt.
⚠ Important: Apply a light coating of the supplied Tef-Gel® or other suitable nickel- or PTFE-based lubricant to the mounting bolts to prevent galling and corrosion.

If you are installing the pedestal onto a steel surface, also use the supplied plastic isolating washers.

Surface mount: rear cable connection

1. Place the mounting template in your desired installation location, observing the correct orientation.
   Note: You can compensate for any minor deviations in orientation later by using the radar’s bearing alignment setting on your multi-function display.

2. Check the location has enough room for the antenna to rotate.

3. Tape the template securely in place

4. Drill pilot holes, then use a 13 mm (0.5”) drill bit to drill the four holes where shown on the mounting template

5. Remove the mounting template.

6. Apply the supplied Tef-Gel® anti-corrosion gel to the four feet of the pedestal.

7. Lift the pedestal using the supplied lifting strap.
   Warning: Do not lift the pedestal with the antenna attached.

8. Lower the pedestal carefully so its mounting holes align with the drilled holes in the vessel.

9. Place a flat washer and spring washer onto each bolt.
   Note: If you are installing the pedestal onto a steel surface, also use the supplied plastic isolating washers.

10. Apply the Tef-Gel® anti-corrosion gel to the threads of each bolt

11. Insert the bolts through the drilled holes and into the pedestal’s threaded mounting holes. Tighten the bolts securely.
    Note: The torque settings for the mounting bolts are 30 N.m – 40 N.m (22.1 lb- ft – 39.5 lb-ft).

12. Connect the 14-pin end of the interconnection cable to the pedestal. Take care to align the connector correctly to avoid bending the pins. Secure the locking collar by rotating clockwise until it clicks.

Pole or tower mount: discreet cable connection

The interconnection cable can be optionally connected underneath the pedestal by moving the 14-pin connector at the back of the pedestal to a bracket underneath the pedestal.

1. Remove the retaining nut and pull out the connector.
2. Remove the blanking plug from the bracket underneath the pedestal.
3. Insert the blanking plug where the connector used to be.
4. Re-route the connector to the bracket and secure it with the retaining nut.
5. Connect the 14-pin end of the interconnection cable to the pedestal. Take care to align the connector correctly to avoid bending the pins. Secure the locking collar by rotating clockwise until it clicks.
6. Apply the supplied Tef-Gel® anti-corrosion gel to the four feet of the pedestal.
7. Lower the pedestal so its mounting holes align with the drilled holes in the mounting plate.
8. Place a flat washer and spring washer onto each bolt.
9. Apply the Tef-Gel® anti-corrosion gel to the threads of each bolt.
10. Insert the bolts through the drilled holes and into the pedestal’s threaded mounting holes. Tighten the bolts securely.
    Note: The torque settings for the mounting bolts are 30 N.m – 40 N.m (22.1 lb- ft – 39.5 lb-ft).

Fit the antenna to the pedestal

Warning: Do not operate the radar without the antenna connected.

1. Remove the waveguide protection cap from the pedestal and the waveguide protection label from the underside of the antenna.
   Note: The cap and label prevent contaminants from entering the waveguide. You should only remove these covers just before you fit the antenna to the pedestal.

2. On the antenna, check the sealing ring is correctly positioned in the groove around the waveguide.

3. Apply the supplied Tef-Gel® anti-corrosion gel to the entire length of each of the four antenna studs.
   Note: If black, isolating washers are factory fitted at the top of the antenna studs, do not remove.

4. Carefully lower the antenna on to the pedestal.
   Note: The antenna can only fit one way.

5. Place a flat washer then a spring washer followed by a dome nut onto each of the antenna studs.
   Note: If black, isolating washers are factory fitted on the underside of the stud holes, do not remove them.

6. Tighten the dome nuts using a socket and torque wrench to 15 N.m (11 lb-ft).
   Note: Using a socket and torque wrench minimizes the risk of damaging the powder-coated surface of the pedestal.

Run the cables

⚠ Warning: The pedestal has a service mode switch, which disables power supply to the radar and stops the antenna rotating during maintenance and service.

1. Check the service mode switch at the back of the pedestal is set to 0 (power supply disabled
2. Remove the circuit board cover from the RI-50 by unscrewing the six retaining screws.
3. Remove the grommet retaining clip.
4. Remove the rubber grommets.
5. Line the following cables up so they face their respective connector on the circuit board:
   • Power cable
   • Ethernet adapter cable
   • Pedestal interconnection cable
   • Any AUX wires for the remote power and antenna park brake functions
6. Pass the cables through the rubber grommets and into the RI-50. For cables with connectors, you need to cut a slit between the hole and edge of the grommet

Connect the interconnection cable

To receive Ethernet data from the radar, connect the RJ45 connector end of the interconnection cable to the SCANNER connector on the circuit board. To provide power to the radar and park brake, connect the six wires of the interconnection cable to the 4-way and 2-way SCANNER POWER connectors on the circuit board, matching the color-coded stickers on the connectors with the wire colours.

If you ever need to replace or refit the 8-pin RJ45 connector on the interconnection cable, use a RJ45 crimping tool and wire as follows:

Connect the power cable

The power supply for the radar is connected to the RI-50 interface module. Depending on radar power demand, the RI-50 can draw up to 20 A average (20 A nominal, 25 A peak) from both 12 and 24 V DC power systems. The RI-50 is protected against reverse polarity, over-voltage and under-voltage. The RI-50 must be connected via a dedicated fuse/circuit breaker rated at 25 A for either 12 or 24 V DC systems. The fuse/circuit breaker should be labeled accordingly. The further away the power supply, the thicker the cable you need

Notes:

• Above values in mm2 = area of copper conductor. Stranded core cables are recommended.
• Conductor sizes greater than 10 mm2 (8-AWG) require a short length of thinner cable (6 mm2
• AWG) to connect into the RI-50 screw terminals.

1. Strip away approximately 10 mm (0.4”) of insulation at the end of each wire.
2. Unscrew the terminal screw from the positive input SUPPLY connector (identified by the + sign) on the RI-50 circuit board.
3. Insert the bare end of the positive wire into the positive input connector to make a connection.
4. Tighten the terminal screw to hold the positive wire in place. Gently pull the positive wire to ensure it is secured.
5. Repeat this process to connect the negative wire to the negative input SUPPLY connector (identified by the – sign).
6. If you have a 24V battery system you want to protect from over discharge, change the 12/24V switch to 24V ONLY.

Ground the RI-50

You can ground the RI-50 using the ground terminal on the underside of the case. The chassis ground is DC isolated from power (–ve) to eliminate the risk of galvanic corrosion. It is recommended that the RI-50 ground is connected to the vessel’s bonded ground or a nonbonded RF ground at the closest possible location, using 12 AWG wire (or thicker).

Alternatively, you can ground the RI-50 using the CASE / SHIP GND spade terminal on the circuit board.

Activate remote power control

The RI-50 has an optional remote power control mode that enables a compatible multi-function display or ignition switch to control the power state of the radar. When the display or switch is turned on, the radar will turn on.

To use the remote power control function:

1. Move the power control switch from Always ON (indicated by ON on the switch itself) to POWER CONTROLLED BY AUX REMOTE (indicated by 1 on the switch).
2. Apply +V DC (5 V DC – 32 V DC) from a compatible multi-function display or ignition switch to the Remote input of the AUX connector. On a compatible multi-function display, this is the yellow wire in the power cable.
3. If you are using a multi-function display to power on the radar, set it to master (refer to the power control function in the display’s user manual for instructions).

Notes:

• If the power control switch is moved back to Always ON, the power wire in the AUX Remote port is ignored.
• If the radar is turned off via remote power control while transmitting, the radar will auto park the antenna before shutting down.
• There must be a common battery -ve for all devices on the power control bus.

The following illustration is an example of a system using remote power control

Activate antenna park

HALO 2000 SERIES and HALO 3000 SERIES radars have the ability to stop rotating the antenna and hold it at a predetermined angle in relation to the vessel’s heading line. This park angle is set in the radar’s software on your multi- function display. In addition, there is a park angle retention feature which is a very low current electromagnetic brake that provides resistance for the antenna to maintain a parked angle against wind and movement when the radar is not powered. The park brake requires a continuous low current DC supply (10-32 V DC). This draws less than 100uA. To activate the antenna brake park function, connect a signal wire from the positive side of the power supply to the Park input on the AUX connector

Connect the network cables

An Ethernet network is used to distribute the radar data to compatible multi- function displays. The RI-50 is connected to the Ethernet network using the supplied Ethernet cable and Ethernet adapter cable (RJ45 male to 5-pin female, 150 mm (5.9”)).

The RI-50 can be connected directly to any Simrad®-compatible multi-function display or to a network switch such as an NEP-2.

Additional radar functions

Additional radar functions such as VelocityTrack and ZoneTrack require good- quality, high-speed GPS position and heading data at 10 Hz or better. The GPS antenna must be mounted in a position that provides a clear view of the sky. A quality 10 Hz compass such as the Precision 9 is suitable for heading, however for the very best performance, a GPS compass such as Simrad® HS75 or HS80A should be considered. The connected multi-function display sends NMEA 2000® position and heading data to the radar via the Ethernet connection. For radar chart overlay, an integrated GPS/compass sensor such as the Simrad® GS25 is suitable, however the compass is not suitable for VelocityTrack and ZoneTrack as it does not have 10 Hz heading output.

The following illustration is an example of a GPS and heading NMEA 2000® network:

Start the radar

When you finish connecting the cables to your RI-50, replace the cover on the circuit board and set the service mode switch on the back of the pedestal to l (power supply enabled).

Fault|  | The fault indicator shows existing conditions as steady colors and historic conditions as blink patterns.

Re-power the RI-50 to clear a fault/warning indication.

| Faults are defined as conditions that could cause damage to the equipment.

Warnings indicate conditions that can cause the RI-50 to change the operating state of the radar, e.g. switching it to standby.

The historic indication helps to identify the cause of intermittent problems.

Off| Normal|
Blue| Under or Over voltage| Low supply voltage to the RI-50
Purple| Over current including short circuits| Input current > 20A or output current > 8A
Red| Over temperature| The internal temperature > 90°C (194°F). Caution: The heatsink case may be too hot to touch.
Red blink| Once the RI-50 returns to a stable state, either RUN or OFF, the fault LED will indicate its last condition.| Blink patterns indicate the type of fault or warning that is detected.

The patterns repeat every 5s. Only one pattern displays at a time. Patterns consist of 1 to 4 blinks with each blink being short (.) or long (-).

Warnings start with short; faults start with long. There are no patterns with all long.

Warning .-.-| Input voltage is unstable. Check the wiring and condition of the battery or power source.
Warning .-.| The AUX: Remote input was OFF, < 2.5V. Check the Remote Bypass switch or the external connection if used.
Warning ..-.| Flat battery or very low input voltage, < 5V (12V) or < 9V (24V). Check the input voltage.
Warning .| Low input voltage in 12V system, < 9.5V. The RI-50 switched to standby due to low input voltage. Could be engine cranking or other heavy load.
Warning ..| Low input voltage in 24V system, < 19V. The RI-50 switched to standby due to low input voltage. Could be engine cranking or other heavy load.
 |  | Warning …| The RI-50 detected voltage on its output before it turned on. If the radar was only off for a short time, it is normal for there to be residual voltage. However, it can also indicate the output switch in the RI-50 has been damaged and needs repair. This will not stop the radar from working, but does

mean the only remaining fault protection in the RI-50 is the 40A input fuse.

---|---|---|---
Warning ….| High input voltage, > 34V. Check your input power source. Input voltages > 36.5V can damage the RI-50.
Fault -.| Output voltage too high, > 54V. There is a risk of damage to the connected pedestal. Get the RI-50 checked.
Fault -..| Average input current too high, > 20A. The RI-50 will retry up to 5 times before shutting down.

Can be caused by low input voltage and/or excessive load from the pedestal.

Fault -…| Average output current too high, > 8A. The RI-50 will retry up to 5 times before shutting down. Caused by excessive load from the pedestal.
Fault -.-.| Typically indicates a short circuit on the pedestal cable. The output current was

10A. The RI-50 will retry up to 5 times before shutting down. Check the pedestal interconnection cable for damage.

Fault -.-| Over temperature, > 90°C (194°F). The RI-50 will re-start after cooling down.

The RI-50 should be mounted as shown in the Hardware mounting section of this manual so that air can flow over the heatsink. Low input voltage and heavy pedestal load will increase heating.

Fault –.| Caused if the wrong pedestal type has been connected. Pedestals designed to work with RI-12 interface modules (older) will not work with RI- 50s and could be damaged.

Can also be caused if the yellow wire in the PARK terminal on the RI-50 (SCANNER

POWER connector) is loose or disconnected.

Fault -..-| A software upgrade is required. Return the RI-50 for service.
Status| Green| Normal operation| Output voltage > 45V. The radar will operate regardless of any fault or warning indication.
---|---|---|---
Green/orange fast blinking| Wrong/no radar connected| Output voltage 16V to 45V. Check the pedestal is connected and it is a compatible model. Also check the yellow wire in the PARK terminal on the RI-50 (SCANNER POWER connector) is secure.
Orange| Pending shutdown| Output voltage 16V to 45V. Typically the radar is given 30 seconds to prepare for shutdown.
Red| Radar is off| Output voltage <16V. Typically the output is off.
Ethernet| Green blink| Successful communication with a multi-function display| Normal operation.

The LED activity increases with increasing Ethernet traffic.

Off| Communication not established| Ethernet cable disconnected or faulty Ethernet cable to display.

Fuse

In the rare event that the non-replaceable fuse blows on your RI-50 circuit board, the BLOWN FUSE LED will light up while power is supplied to the RI-50. This indicates an internal fault and you will need to replace your RI-50 unit.
Note: A blown fuse indicates an internal fault with your RI-50. It does not indicate a fault with the external wiring to the RI-50 or a fault with the radar pedestal.

SETUP AND CONFIGURATION

Adjust settings
Make the following settings before use. Refer to the documentation supplied with your display unit to locate and adjust the settings.
Radar source
In a system with more than one radar, the device to configure is selected from here.
Note: Radars that support dual radar mode are represented twice in the source list, with an A and a B suffix.
Radar status
Used to view information about your radar, such as the software version, serial number and operating hours.
Antenna setup
X-axis and Y-axis. Used to set the approximate position of the antenna on the vessel. This enables your vessel icon to be positioned correctly on the PPI. Height. Used to set the height of the antenna above the water line. Ensure the antenna height is set correctly, as it affects the sea clutter function. Do not set the height to zero. Span. Used to select the length of your antenna.
Adjust bearing alignment
Used to compensate for any slight misalignment of the pedestal during installation and to make sure targets and bearings taken with the electronic bearing line display accurately. The adjustment is made by aligning the heading marker on the screen with the center line of the vessel.
Sidelobe suppression
Used to increase the suppression if there are false targets appearing as arcs radiating from either side of an actual target (typically large structures such as steel hulled ships, container wharves and large buildings). By default this control is set to Auto, and normally should not need to be adjusted.
Note: This setting should only be adjusted by experienced radar users. Target loss in harbor environments can occur if it is not adjusted correctly.
Sector blanking
Used to stop the radar transmitting in the direction of structures that could cause unwanted reflections or interference to appear on the radar image. Four sectors can be set, the bearing of which is measured from the bow of the vessel to the center line of the sector.
Adjust open array park angle
Used to set the resting position of the antenna relative to the heading line of the radar when the radar is set to standby. The antenna will stop rotating at the desired offset. Optionally, the antenna can be held in place against wind by connecting the antenna park wire.
Note: When entering standby, the antenna may rotate multiple times before coming to rest.
HALO light
Used to control the brightness level of the blue LED accent light on the pedestal. There are four brightness levels. The level can only be adjusted when the radar is in standby mode.
⚠ Warning: The pedestal’s blue accent lighting may not be approved for use in your boating location. Check your local boating regulations before turning the blue accent light on.
Reset radar to factory defaults
Used to reset the radar’s control settings (not installation settings) to their factory defaults.

Update software

Before you operate your radar, we recommend you check it’s running the latest software version. If your MFD is connected to the internet, it automatically detects if there’s a newer version for any connected radar. Go to Settings > About > Support > Check for updates (or Settings > General > Software updates depending on your unit) and follow the prompts to download and update. If your MFD isn’t connected to the internet, compare the version listed under the Radar status setting with the version available on the Simrad website. If the software needs updating, download the software file from the website onto a microSD® card. Insert the card into the microSD® slot on your MFD. From the home screen on the display, select Storage, select the microSD® card and select the file. Follow the upgrade prompts. Some MFDs also allow you to transfer software updates using a USB storage device. When you insert a USB device or microSD® card with a newer software version into these units, they automatically move the file to the right location and prompt you to update the radar’s software.

UPGRADING

HALO 3000 SERIES radars have higher current draw than HALO 3/4/6 SERIES radars due to a more powerful motor and higher transmit power. If you are upgrading from a HALO 3/4/6 SERIES radar to a HALO 3000 SERIES radar, you should change the interconnection cable. If you are upgrading from a HALO 3/4/6 SERIES radar to a HALO 2000 SERIES radar, you may use the existing interconnection cable but we recommend you inspect the condition of the connectors.
Note: At the time of release, HALO 2000 SERIES and HALO 3000 SERIES radars work with Simrad® NSX® GO XSR, GO XSE (9/12), NSSevo3, NSSevo3S, NSOevo3, NSOevo3S and NSOevo3S MPU systems. They also work with Simrad® R2009 and R3016 radar control units.
