GPS OPERATION

GPS operation
NOTE: The built-in GPS receiver cannot calculate
its position data if it cannot receive signals from the
GPS satellites.
The transceiver has a built-in internal GPS receiver.
The GPS receiver's position data can be received in
any mode. Also, a NMEA format compatible external
GPS receiver can be connected to the transceiver
through the [DATA] jack.
To receive signals from an external GPS source,
connect an external NMEA format compatible receiver
to the transceiver according to the instructions, shown
to the right.
Position data can be transmitted in only the DV mode.
