Detail
If an alarm panel (APYYYY) is connected please check there is a light in the red “VHF
DISTRESS” button. If not lit, fuses might need replacement in the alarm panel before the
serial bus is operational.
Communication problems will not affect 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 with the following:
• VHF
• Serial Number - found on the rear side of the radio - see Figure xx - or via the menu
item 4.6.1.2
• Firmware version - reported via menu item 4.6.1.1
5.2.6 Missing MMSI
Symptom: DSC function is not working
If you have powered your VHF for the first time it might not have the MMSI number pro-
grammed. You must program the MMSI number before the radio is operational for DSC.
Programming is done via menu item 4.5.1
5.2.7 Radio Time
Symptom: DSC logs are sorted with a wrong time stamp, or radio time is not correct.
The problem with a wrong radio time should only occur if the GPS is not connected in the
system. A valid GPS time signal will update the UTC time that is used for time stamping logs
only.
If you have a system without GPS, where you manually update position and time, it is also
required that you enter the radio time - at least right after power-up, if you want to get correct
time stamps on DSC logs. The UTC time is also used as the proposed time each time you
are requested to enter position and time manually (each 4 hours).
