3.6 GPS Data and Time (GPS/DATA)
If the boat has an operational GPS navigation receiver, 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 symbol will be shown whenever GPS data is not available from an operational GPS
navigation receiver.
