General Operation

Buttons to navigate through Menus
In the menu system, certain controls have some common functions to help you move through the menus:

  1. Volume control centre switch = select
  2. Volume control rotary = “choose”
  3. Hang Up (Return on non-BT models) = return or move back up a menu level

Powering On/Off
To switch the unit on press the power button. To turn the unit off, press and hold the power button for 2 seconds.
In a similar manner, many of the buttons on the front panel have two modes of activation: “Short press” and “Long press” to directly select different functions.

The ‘Volume’ Knob
Audio volume is adjusted when the rotary knob is turned, and MUTE is toggled on/off when the knob is pressed briefly – short press.
In the SYSTEM or AUDIO menus, volume adjustment is temporarily disabled, and the rotation of the knob adjusts the value of the menu item. In this mode pressing the volume knob will select the item, you have chosen. The menu list may also be cycled through with the >>| and |<< buttons.

TURN for Volume adjustment/PRESS to MUTE TURN to choose/PRESS to select

Example: short press (push and let go) the MENU button to access the AUDIO menu – EQ, loudness, bass, treble, balance, and fader.
Radio Operating Region
When the radio is first powered up or after a reset, it will ask you to select the geographical radio operating region, use the rotary control to choose your region, and press the knob to select.
This can also be set using the Radio Mode menu – all menus are context sensitive i.e. radio-only functions can only be accessed in radio mode.
REGIONS AVAILABLE

Bluetooth Operation

(not available on RM1800 and RM1900 non-BT models)
General Operation

When paired to a mobile phone Bluetooth-enabled radio models, allow the user to perform hands-free calling via the radio. The radio has “Answer” and “Hang- Up” buttons to accept or reject an incoming call.
When no call is active the “Answer” button can be used to re-dial the last number – pressing once asks if you want to re-dial, pressing again dials the number, and pressing the “Hang-Up” button cancels the request.
The external microphone should be fitted in a position close to the operator. Bluetooth Profiles
Bluetooth-enabled units can wirelessly link to Bluetooth devices such as mobile phones. The modes of Bluetooth connection are referred to as “profiles”. This radio supports the following profiles:

  1. A2DP: Advanced Audio Distribution Profile – Playing (Streaming) music using Bluetooth. Devices that have A2DP functionality can stream music into the radio to be played through the vehicle’s loudspeaker system.
  2. AVRCP: In addition, if supported by the device, the AVRCP profile (Remote Control Profile), allows functions like ‘next track’ and ‘previous track’ to be controlled from the radio.
  3. HFP: Hands-free Profile – Making or receiving telephone calls using Bluetooth.
  4. SSP: Secure Simple Pairing – this method is based on a random number generator and the user does not need to enter a PIN number on the phone.

Pairing
To use the Bluetooth hands-free function a mobile phone needs to be “paired” to the radio. To “pair” the mobile phone with the radio ensures that the radio is turned on. On the mobile phone search for Bluetooth devices and select the radio model number. Check for a successful pairing notification on the mobile phone.
Once paired it is the mobile phone that determines automatic reconnection to the radio. (e.g. on re-entry to the vehicle with the ignition on).
To disconnect a Bluetooth device temporarily use the “DISCONN” (disconnect) menu function. To permanently remove a pairing, use the “UNPAIR” menu function.

Radio FM/MW/LW

Searching for Radio Stations
Use the >>| and |<< buttons to search for radio stations: short press to automatically seek the next available frequency (jump to the next seek to stop).
Manual Tuning
Long press either the >>| or |<< button to change to manual-seek mode. In this mode, a short press of one of these seek buttons changes frequency one step at a time whereas a long press will scroll until the button is released. The radio will revert to auto-seek mode if either button is not operated for 3 seconds.
AutoStore Radio Stations
Long pressing the BAND button will start an “auto store” sequence to scan the whole band and store the strongest stations found.
Storing and Recalling Radio Stations
When listening to a radio station a long press on one of the radio preset buttons will store it permanently. The current station will be saved. A stored radio station can be recalled by a short press of one of these buttons. The stored radio station can be updated by tuning to a different station and performing a long press.

Short press: Recall the stored station.

RDS (see also “Radio RDS Notes” )
AF: Alternative Frequency
TA: Traffic Announcement
TP: Traffic Program
PTY: Program type

Radio RDS Notes
When RDS (Radio Data System) is operating the radio will show the station name e.g. “BBC R1” rather than the frequency. RDS is only available on the FM band. If RDS service is not available, the radio operates in conventional FM radio mode.
AF: Alternative Frequencies. When this feature is enabled, the radio can stay tuned to BBC R1 by automatically returning the reception frequency when the first signal becomes weak such as when the vehicle has moved out of range, providing that a stronger signal on the alternative frequency is available. Channel switching to the same radio station is performed automatically. In fringe reception areas the user may switch off AF if silent frequency seek is experienced frequently. Choose the AF menu item and select OFF.
TA: Traffic Announcement. When switched on, if a traffic announcement is available the radio will automatically switch to the station broadcasting the announcement until it is complete. The TA menu item toggles between TA ON and TA OFF.
TP: Traffic Program – An indicator is displayed if the currently tuned station is a traffic announcement-capable station.
PTY: Program type. RDS broadcasting services categorize the type of programs for the listener. Examples are NEWS, AFFAIRS, INFO, SPORT, EDUCATION, DRAMA, CULTURE, SCIENCE, POP M, and ROCK.

Radio Preset Notes
FM has 3 bands, FM1, FM2, and FM3 bands each band has 6 radio presets. In total there are 18 FM radio presets for the user to store pre-tuned radio stations.
MW has one band with 6 radio presets, as does LW. There are 12 AM (MW & LW) radio presets.
DAB mode also has 3 “bands”, DAB1, DAB2, and DAB3 each with 6 presets to store your favorite stations.
In total there are 5 x 6 = 30 radio presets and 18 DAB presets available to the user. The radio stores these permanently on an EEPROM memory device, that does not require external power to retain the radio station preset memory.

Radio DAB/DAB+

Digital Audio Broadcasting – DAB/DAB+ Mode
DAB is a terrestrial digital transmission system. DAB stations bundle radio programs (“Services”) into an ensemble. Each ensemble contains one or more radio services. The same service can sometimes be received on different frequencies.
DAB/DAB+
To listen to DAB radio press SRC to select “DAB/DAB+”. When the DAB band is selected for the first time an initial scan is needed. The radio will ask for confirmation to do this – press the volume control knob to start scanning. Allow the initial scan to finish. (If interrupted, the initial scan will be requested again the next time you select the DAB mode)
Tuning DAB Stations
Enter the DAB system menu with a long press on the MENU button and select SCAN to perform a full scan of the DAB band.
To update the station list (usually because you have moved to a different geographical region) enter the DAB system menu and select PRUNE to clean up the stored list of DAB stations.
Selecting a DAB Station
Method 1: Use the >>| and |<< buttons to select the next (or previous) DAB station in the alphabetically sorted list of stations.
Method 2: PREFERRED – Long press the BAND/BROWSE button to select the BROWSE feature. This will allow you to use the rotary volume control knob to scroll through the DAB station list. Press the volume knob to select the station name you want.
Storing and Recalling DAB Stations
To store a favorite station press and hold down one of the user preset buttons 1 – 6 until a beep is heard or “SAVED” is displayed. To recall any one of your preferred stations, briefly press the desired preset button.

Radio DAB/DAB+
Notes When there is no reception, “NO STATION FOUND” scrolling text is shown on the display. Use the “seek up” () or “seek down” () button to search for the next available DAB radio broadcast.
When the reception is lost for approximately 15 seconds “NO SIGNAL” is displayed.
DAB is a digital system and as such, it either works and clear audio is heard or it does not work and the audio is muted. This is unlike a traditional FM broadcast that becomes increasingly noisy but may still be intelligible.

Media USB

One single media device can easily fit thousands of songs (audio tracks). These tracks are often referred to as MP3 and WMA. Without any specific metadata, the radio uses the track filename as the title. Tracks can be put into folders and sub-folders.
For media carriers such as USB sticks, the unit can play files inside sub- folders.
Avoid having too many levels of depth in the sub-folders.
Do not carry too many audio files on a media to avoid difficulty in finding the desired song/track.
Media software and hardware are updated at a fast pace, so although the radio is shipped with the latest media compatibility; newer USB sticks and/or new file formats may not be compatible.
Listed below are the alternative functions of various keys on the front panel for media playback.

Reset – Software / Hardware

Soft Reset – MENU – RESET: If the user is not sure if settings on the radio have been altered inadvertently, restoring the factory default settings may help. On reset factory settings will be reloaded, overwriting the current data selections with their default values. This includes such items as BT pairing, station presets tone settings, etc.
Hard Reset – A hardware reset button is located on the front panel (see “Front Panel Layout”) and can be activated by a paper clip or pen. This is only necessary if the radio refuses to react to any button input.

Power Off Timer

This radio has a power-off-timer enhancement feature. The setting for this is accessed by a long press on the MENU button (system menu), in any mode, and using the >>| or |<< buttons to select the timer menu. Settings are OFF AUTO, 30 min, 60 min, and 90 min. OFF is the factory default value where the radio powers off immediately when the ignition key is switched off. This is the same as conventional radios.
AUTO mode will switch off the radio with the ignition, but you can turn the radio back on (or off) for a 30-minute period.
30, 60, or 90 minutes will keep the radio playing for this time after the ignition is switched off. Turning the radio off manually will cancel the timer and the radio will not switch on until the ignition is also turned on.
This countdown timer is shown on the display using the small secondary line of characters. In the last 5 minutes of the count-down time, the main display will warn the user that the radio is about to shut down.
This feature extends listening time and allows the ignition key to be removed for safety reasons. It also prevents the battery from being drained if the radio is left turned on for an extended period. The exact availability of this feature depends on the type of the vehicle since both a switched ignition “ACC” wire and a permanent battery “B+” wire are used to control this function and must be connected to the radio.

Wiring Notes

Connections are to be made at the rear of the unit during installation.
Connector A pins:
A4. B+ or BATT +12V
When the radio is turned on electrical power is supplied to the internal electronics of the unit through this pin. Main consuming blocks such as audio power amplifier and backlights draw power from this pin. Ensure the connecting wire has a minimum AWG14 wire gauge to carry the current.
A5. AUTO ANTENNA OUTPUT +12V
The voltage state on this output pin is a direct indicator of whether this unit is powered on or off. It can be used to control ancillary equipment such as an automatic electric antenna or an audio power amplifier. When connected properly such ancillary equipment will power on and off automatically in sync with the radio.
A7. ACCESSORY (ACC) or IGNITION +12V (key position)
Normally connects to the ignition or accessory circuit. By sensing the voltage on this pin, the unit is able to automatically power on and off when the ignition key switch is turned on or off.
A8. CHASSIS GROUND (EARTH)
All electrical current from this pin is combined to complete the power supply circuit. Ensure the connecting wire has a minimum AWG14 wire gauge to carry the current. The metal enclosure of this unit is grounded to this pin. The unit is only suitable for “negative earth” vehicles.
PINS A4 and A7 B+ (BATT) and ACC (IGNITION) CAN BE SWAPPED BY CHANGING THE POSITION OF THE FUSE – SEE DIAGRAM BELOW
Connector B pins (loudspeakers pins):
B1. REAR RIGHT (+)
B2. REAR RIGHT (-)
B3. FRONT RIGHT (+)
B4. FRONT RIGHT (-)
B5. FRONT LEFT (+)
B6. FRONT LEFT (-)
B7. REAR LEFT (+)
B8. REAR LEFT (-)
IMPORTANT NOTE: Always replace the fuse with the same type and rating. A blown fuse usually indicates a problem in the circuit. Do not rely completely on replacing the fuse to fix a problem. An over-rated fuse will compromise protection against over-current. Under-rated fuses can blow even if a fault condition does not exist.
