5.2.3 GPS

Sympton: Position requested.

If your radio is connected to a GPS and you receive a request in the display to enter position

and time, then it is possibly that the GPS unit is either turned off, broken or disconnected.

The GPS is connected on the rear side of the radio, either directly to the option connector or

via connection box (see section Interface connections). Please refer to installation section of

this manual for connection details.

Until GPS signal has been restored you must update the position manually as requested by

VHF.

5.2.4 Accessory connection

Symptom: Some or all of the remote units do not work

First turn your VHF off and on. Turn all remote units on, if possible. Check status of the units

by going into the Accessories menu 4.6.2. In this menu you can read the status of any

connected device. If the status is “not found” for a particular device, it cannot be recognized

by your VHF.

The communication to the remote units is taking place via a serial multi-drop bus connection

on the rear side of the radio either directly to the SPARC II connector or via connection box

and/or extension box (see section Interface connections).

If an alarm panel (AP4365) is connected please check there is a light in the red “VHF

DISTRESS” button. If not, fuses in the alarm panel might need replacement before the serial

bus is operational.

Communication problems will not affect the VHF unit functionality.

5.2.5 Device failure

If any of the checks descibed above does not explain or help to solve the problems you have

discovered, the problem might be related to the unit itself. Now you must call the authorized

workshop that will make the necessary repair. When you report that you need service for

your device, you can inform your dealer about the problem you see and give the following

information:

• VHF

• Serial Number - e.g. found via the menu item 4.6.1.2

• Firmware version - reported via menu item 4.6.1.1
