2-9.3.2 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-Z transceiver on and let it operate for at least 15
minutes.
2-9.3.3 Operating Instructions
2-9.3.3.1 Switching to the GPS Display
NOTE
You cannot switch to the GPS display if you are using the ALE mode.
1. Select the GPS item by scrolling with the MORE key on the FREQ or CH menu, and then
pressing F2. You will see a message that indicates the current display format, GPS LLA or GPS
ECEF.
2. If necessary, switch to the alternate display format by pressing the UP or DOWN key.
Alternatively, you can use the GPS menu: press MORE as required to see FMT, and then press
the key next to FMT (F4).
3. If the GPS receiver operates normally and is ready, you will see the information selected the last
time the receiver has been used.
2-9.3.3.2 Selecting what to Display
1. Press the key next to the type of information you want to see: use Figure 2-4 to find the key to
be pressed.
2. The displayed information appears on the display and is automatically updated every second.
The time is updated every 5 seconds.
3. To change the display of GPS information, scroll to the desired item.
4. To cancel the display of GPS information, select any other menu except GPS.
2-9.3.4 What to do if …
1. If the GPS display mode, GPS LLA or GPS ECEF, does not appear when switching to the GPS
display, scroll to the DEV item. You should see the GPS receiver type.
• If you see UNKNOWN, turn the Micom-Z transceiver off and after a few minutes turn it back
on. If the problem persists, the GPS receiver must be serviced.
• If you see NONE, your Micom-Z transceiver does not include the optional GPS receiver.
2. If the requested information does not appear within 15 minutes, but the check in Step 1 above is
successful, check for proper connection of the GPS antenna cable to the rear GPS antenna
connector of the transceiver.
3. After checking that the antenna is properly connected, check that the GPS antenna did not shift
from its intended position, and has a clear view of the sky. Try to improve your location: avoid
locations near trees, high buildings or steep hills.
