GPS Screen Information and Operation
Tips
The GPS data units for position, speed and altitude may be changed by pressing and holding the
key for over one second to enter Set mode, then select [APRS][22 GPS UNIT].
When the GPS function is used, the accurate time and date are obtained from GPS and shown on
the LCD in 24-hour format. This time data is displayed on the GPS and APRS screens.
The geodetic system datum (WGS-84 / Tokyo) of the built-in GPS unit may be changed by selecting
[APRS][19 GPS DATUM] in Set mode. However, since APRS uses the geodetic system of
WGS-84, it is recommended not to change it.
The time zone may be set at 30-minute increments by pressing and holding the
key for over
1 second to enter Set mode, then selecting [APRS][28 TIME ZONE] (the default setting: UTC
0:00).
When the GPS function is active, the power consumption increases by about 30 mA. As a result,
the battery life is reduced by about 20% compared to when the GPS function is deactivated.
The position information obtained from an external GPS device may be used by pressing and
holding the
key for over one second to enter Set mode, then selecting [APRS][17 COM
PORT SETTING] and then setting [INPUT] to [GPS]. In this case, the data from the internal GPS
will be ignored.
When using an external GPS device, move it away from the transceiver to reduce interference.
