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.
