2-6 GPS Data and Time (GPS/DATA)
If your vessel has an operational GPS navigation receiver, the 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 you transmit a DSC distress call.
2-6-1 Manually Enter Position and UTC Time (MANUAL)
NOTE: This function is available only when an operational GPS receiver is NOT connected.
1. Select GPS/DATA, then MANUAL.
2. Enter the latitude, then the longitude, then the UTC.
3. Press ENT or push the rotary knob when all the information is correct.
The vessel’s latitude and longitude are shown on the screen, with the UTC time. After entering your
manual LL position, the prefix “M” in the normal GPS screen indicates a manual entry. The manual entries
are cancelled if a real GPS position is received.
