Connecting to a GPS Receiver
If you connect the radio to a GPS receiver, the radio can automatically transmit your current position during an automated distress
call or during a normal DSC call.
Your radio supports a standard NMEA0183 input from a GPS receiver. Follow the steps below to connect your radio to your GPS
receiver:
1. Connect the GREEN wire of the included accessory cable to the GPS DATA OUTPUT (-) WIRE or the GROUND WIRE on your
GPS receiver.
2. Connect the YELLOW wire of the included accessory cable to the GPS DATA OUTPUT (+) WIRE on your GPS receiver.
3. Be certain all wire connections are secure and that all open wires are adequately covered.
NOTE: to extend the life of the radio, use waterproof tape to seal electrical connections.
4. Plug the accessory cable into the accessory cable pigtail on the back of your radio.
GPS Verification
If the GPS receiver is correctly connected and it transmits valid data, the display shows
GPS Data OK
. Press
ENT-1W25W
to
open the GPS status screen and see detailed GPS data:
If the GPS does not send coordinates within 30 minutes, an audible alert sounds once and the display shows
Input GPS
. This message
remains until the coordinates are updated.
After 4 hours, the audible alert sounds again if no coordinates are received and the GPS is connected. After 23.5 hours, the radio
deleted the current coordinates and displays
Input GPS
.
See page 12 to manually set the GPS coordinates.
Configuring the GPS
If the radio is receiving valid GPS data, it will automatically set the clock to your local time based on the GPS location. You can
adjust your local time forward or back one hour if necessary (for example, if you are close to the border of a time zone); you can
also adjust for Daylight Savings Time.
