3-6 GPS data and time (GPS/DATA)
If the boat has an operational GPS navigation receiver and is connected by NMEA port, the
VHF radio automatically detects and updates the vessel position and the local time.
However, if the GPS navigation receiver is disconnected or absent, you can specify the vessel
position and the local time manually, using the GPS/DATA option.
This information is important because it will be used if a DSC distress call is transmitted.
• If GPS data is NOT available for some reason, the NO GPS alert will sound for 5 seconds (or
until you press any key) and the radio requests you to enter the position data manually
• This request is repeated every 4 hours if you do not enter the position data manually.
After you have entered the position data manually, you must update it within 23.5 hours
otherwise the NO GPS alert sequence repeats
• The NO GPS warning will be shown whenever GPS data is not available from an operational
GPS navigation receiver.
