First-Time Operation
The internal GPS receiver is always powered when the transceiver is turned on. Therefore, if the GPS
antenna is connected and you are in a good place with a clear view of the sky, the GPS receiver can
start the satellite acquisition process as soon as the transceiver is turned on, and can then track the
satellites continuously.
Thus, the
GPS
item on the FREQ or CH menu only enables/disables the display of GPS data: the
result is that after selecting
GPS
, the GPS data can be immediately displayed, and is updated once per
second (time is updated once every 5 seconds).
Before using the GPS receiver, turn the MICOM-3 transceiver on and let it operate for at least 15
minutes.
