Install the Universal Boat Mount (select models)

Use the following instructions to install the MEGA Live Imaging transducer on your boat. It can be installed directly to the boat using the included GeigerTec dual-purpose base (select models), or using a Cannon® Mounting Track (separate purchase required). If you are using a different universal mount, follow the instructions included with the mount. It is important to read the instructions completely and understand the mounting guidelines before you start the installation.

Prepare for Installation

1. Test run the Ethernet cable from the chosen mounting location on the boat to the control head or ethernet switch. Test run the power cable from the chosen mounting location to the main switch or fuse panel.
   It is important to consider the following:

   • The MEGA Live Imaging transducer is powered separately from the control head. It must be connected to a switch where it can be powered on when the boat is underway and powered off when it is docked.
   • The cables should be routed through an established routing system on the boat, in an area with minimal interference, without sharp edges, obstacles, or obstructions that may damage the cables.
   • The cables will move as the mount adjusts for the MEGA Live transducer deployment and stowing, so it is important to allow enough length for movement.

2. When the transducer is deployed, it has the following installation requirements:

   • The transducer should not have anything obstructing the ‘view’ of the beams. If possible, move anything to the sides and below the transducer that might obstruct the sight line of the beams.
   • The transducer should be submerged below the keel and/or skeg.

Install the Dual Purpose Base

Proceed to the instructions for your installation method:

• A. Direct Installation
  OR

• B. Cannon Mounting Tack Installation (separate purchase required)

Direct Installation
Use the following instructions to install the GeigerTec dual-purpose base (included with select models) directly to the boat:

1. Determine where to mount the dual-purpose base. Use a level to locate a suitable, flat area on the decking or gunwale. Confirm that the boat is level on the trailer, both from port to starboard and from bow to stern, by placing your level on the deck of the boat, first in one direction, then in the other.

2. Clean and dry the mounting surface.

3. Position the base in your selected location. Mark the four mounting bolt locations with a pencil (see the illustration Installing the Bolts).

4. Set the base aside, and use a 1/4″ (6.35 mm) drill bit to drill the four marked holes.
   NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.
   NOTE: If the mounting surface is thin or made of lightweight material, you may need to add reinforcing material below the mounting surface to support the universal bracket.

5. Place the base on the mounting surface and align the bolt holes with the drilled mounting holes. Apply anti-seize to the four 1/4″-20 bolts (not included) and insert them through the bolt holes and into the drilled mounting holes.
   NOTE: Apply marine-grade silicone caulk or sealant (separate purchase required) to both bolts and drilled holes as needed to protect your boat from water damage.

6. From under the deck or gunwale, install the 1/4″ fender washer and the 1/4″ – 20 nylon insert hex nut (not included) onto each screw. Hand-tighten only! Use an adjustable socket or wrench to hand-tighten the nuts until they contact the washers. Then tighten the nuts an additional 2 full revolutions. Hand-tighten only!

Confirm the Baud Rate (for devices connected to the Sensor pigtail only)

If there is an accessory, such as an autopilot, connected to the Sensor pigtail cable wires, you will need to confirm that the devices are communicating at the same baud rate. The baud rate details are as follows:

• If the GPS Receiver/Heading Sensor is connected to the control head, and NMEA Output is turned on, the control head will operate exclusively at a baud rate of 38400. If there is an accessory attached to the Sensor’s pigtail, it also needs to operate at 38400. See your accessory installation guide to set the baud rate to 38400.
• If NMEA Output is turned off, then baud rates 4800, 9600, and 38400 are available on the control head and no further action is required.

Set up the Network
After you have confirmed all connections, the MEGA Live Imaging transducer is ready to use on the water. Proceed to your MEGA Live Operations Manual to set up the temperature source and additional sonar sources.

Power Off
WARNING! When the boat is stored or at dock, the MEGA Live Imaging transducer must be turned off to prevent draining the battery.

Power Off the Control Head

1. APEX/SOLIX Series: During operation, tap the top, right corner of the status bar or press the POWER key, and select Power Off. HELIX Series: Press and hold the POWER key.
   CAUTION! Turning off the control head will NOT power off the MEGA Live Imaging transducer.

2. Turn off power on the main switch, breaker, or battery switch. Powering off the MEGA Live Imaging transducer will be determined by the installation and power connection on your boat.

Travel with the MEGA Live Transducer Installed
The transducer must not hit the deck, base, or any objects. This is critical during transport.

For models with the GeigerTec mount: Loosen the bracket arms and rotate the bracket so that the MEGA Live Transducer is safely stowed along the deck or gunwale. Check the stability of the universal bracket after initial use and periodically thereafter to ensure that the knobs are tight.

WARNING! During transport, on water or on land, it is important to stow the MEGA Live universal mount inside the rub rail of the boat.

Maintenance

Your Humminbird fishfinder is designed to provide years of trouble-free operation with very little maintenance. Use the following procedures to ensure your Humminbird continues to deliver top performance.

Control Head Maintenance
It is important to consider the following precautions when using your Humminbird control head:

• Chemicals, such as those found in bug spray and sunscreen, may cause permanent damage to the control head screen. Such damage is not covered by the warranty.
• NEVER leave the control head in a closed car or trunk. The high temperatures generated in hot weather can damage the electronics. Use the following information to keep the control head and screen clean.
• Screen: To clean the control head screen, use a mild soap (such as a nonabrasive liquid hand soap) and warm water. Wipe the screen dry with a soft cloth. Be careful to avoid scratching the screen. If water spots remain, use a solution of water and vinegar.

WARNING! Do not use a chemical glass cleaner on the screen. Chemicals in the solution may cause cracking in the lens of the unit.

NOTE: Do not wipe the screen while dirt or grease is on the screen.

• Control Head: If the control head comes into contact with salt spray, wipe the affected surfaces with a cloth dampened with fresh water.

Transducer Maintenance
Use the following information to maintain the transducer operation.

• If your boat remains in the water for long periods, algae and other marine growth can reduce the effectiveness of the transducer. Periodically clean the face of the transducer with a cloth dampened with fresh water.
• If your boat remains out of the water for a long period, it may take some time to wet the transducer when it is returned to the water. Small air bubbles can climb to the surface of the transducer and interfere with proper operation. These bubbles dissipate with time, or you can wipe the face of the transducer with your fingers after the transducer is in the water.

MEGA Live Imaging Maintenance
Use the following information to maintain the installation of the MEGA Live Imaging Transducer.

• Check the stability of the universal mount after initial use and periodically thereafter to ensure that the installation remains stable.
• If your boat will be in long-term storage, remove the MEGA Live Imaging transducer and store it in –40°F to 158°F (–40°C to 70°C), dry conditions.

Troubleshooting

Before contacting Humminbird Technical Support, please read the following section. Taking the time to review these troubleshooting guidelines may allow you to solve a performance problem yourself, and therefore avoid sending your unit back for repair.

“Out of the Water” Error Displays when MEGA Live Is in the Water

Use the following instructions if your fishing system is displaying an “Out of the Water” error message for your MEGA Live Imaging TargetLock when it is in the water. Remove your MEGA Live Imaging transducer from the water. Place a wet piece of cloth over the two metal contacts on the surface of your transducer. If your transducer still does not work, contact Technical Support. If your transducer works with the rag, perform the following troubleshooting tasks:

1. Confirm that the drain/shield wire is connected to the boat’s chassis ground terminal (see note).
2. Confirm that your MEGA Live is not connected to a trolling motor battery as this can create a problem with grounds. Ensure that your MEGA Live is connected to the starting battery or to the house batteries you use for your other electronics. Ensure that the trolling motor batteries are properly isolated from the rest of the boat’s wiring.
3. If your MEGA Live is now working, there is likely a wiring issue. Check the wiring on the starting and house batteries, if present. If using a house battery system, ensure that it is grounded to the boat’s chassis ground terminal (see note).
4. If you have an aluminium boat, ensure that no exposed wires are touching the hull of the boat and that the boat’s hull is properly grounded to the boat’s chassis ground terminal (see note).
5. If all these steps have failed, contact Humminbird Technical Support.

NOTE: The boat’s chassis ground terminal is where the boat’s engine is grounded.

Fishing System Doesn’t Power Up

If your Fishing System doesn’t power up, use the installation guide that is included with your Fishing System to confirm specific details, making sure that:

• the power cable is properly connected to the Fishing System control head,
• the power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground, and the drain/shield wire to the boat’s chassis ground terminal,
• the fuse is operational, and
• the battery voltage of the power connector is at least 12 Volts.

Correct any known problems, including removing corrosion from the battery terminals or wiring, or replacing the battery if necessary.

Fishing System Defaults to Simulator with a Transducer Attached

In addition to the MEGA Live Imaging accessory transducer, you will have a standard Humminbird transducer connected to the control head. A connected and functioning transducer with built-in temperature will cause the newly started Fishing System to go into Normal operating mode automatically. If, when you power up the Fishing System, it goes into Simulator mode automatically, even though a transducer is already connected, this means that the control head is not detecting the transducer. Perform the following troubleshooting tasks:

• Check the connections of all transducers that are connected to the control head or Ethernet network. See the transducer installation guide that was included with your Fishing System for connection information.
• Review this MEGA Live Imaging installation guide to confirm that the transducer cable is connected correctly to the Fishing System. Reconnect if necessary, and power on the Fishing System again to see if this fixes the problem.
• Replace the non-functioning transducer with a known good transducer if available and power up the control head again.
• Check the transducer cable. Replace the transducer if the cable is damaged or corroded.

Finding the Cause of Noise
Electrical noise usually affects the display with streaks or repetitive patterns on the view. One or more of the following sources can cause noise or interference:

Possible Source of Noise/Isolation

• Other electronic devices Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time to see if the noise re-appears.
• Other sonar devices Turn off any nearby sonar devices to see if the problem goes away, then turn them on one at a time to see if the noise re-appears.
• The boat’s engine To determine whether the boat’s engine is the source of the noise, increase the RPMs while the boat is in neutral and stationary to see if the noise increases proportionately; if noise appears when you rev the engine, the problem could be the spark plugs, alternator, or tachometer wiring. Replace the spark plugs with resistor plugs, install an alternator filter, or route the control head power and transducer cables away from the engine wiring.
