GPS O
PERATION
The VX-8DR/DE allows the display of your position (Longitude/Latitude) when using
the optional FGPS-2 GPS Antenna Unit.
1. Make sure that the transceiver is off.
2. Connect the optional FGPS-2 GPS Antenna Unit to the MIC/SP jack of the trans-
ceiver via the optional MH-74
Antenna Adapter (see next page).
3. Press and hold in the
4. Press the
key until the GPS screen appears.
5. When the transceiver succeeds in receiving a valid GPS
signal, your current position (Longitude/Latitude), current
time (UTC), and altitude will appear on the display. Rotate
the DIAL knob (or press the
additional lines of station text on the display.
The received satellite number appears at the lower right of
compasses (In the example at the right, it is 4 satellites).
When receiving a signal from more than 3 satellites, the "
display.
Advice: 1) When the FGPS-2 GPS Antenna Unit is first turned on, it may take sev-
eral minutes to compute a fix of your position. This is normal, as the GPS unit is
downloading "almanac" information from the GPS satellites.
2) While the VX-8DR/DE searches for a GPS signal, the compass icon does not appear
on the display and the position information (Longitude/Latitude) blinks on the display.
3) If the transceiver does not receive a valid GPS signal after three minutes have
passed, you may be in a poor location for satellite reception, such as inside of a house
or building; try moving to a less obstructed position.
6. If you walk a few meters from your current location, your
course direction is displayed on the compass of the display
and walking speed is displayed in the "SPD" column of the
display.
7. Press the
The course direction displays a black arrow in the "North Up" screen, and displays a
white arrow in the "Course Up" screen.
8. To return to normal operation, press the
appears.
1) When the VX-8DR/DE GPS signal is interrupted; such as when you enter into
a tunnel, the compass icon disappears from the display but maintains the position
information (Longitude/Latitude) at the point where the GPS signal was lost.
2) When the FGPS-2 GPS Antenna Unit is activated, the current consumption increases
approximately 40 mA. Therefore, battery life is reduced by approximately 20 % when
the FGPS-2 GPS Antenna Unit is activated.
