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-3 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-3 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.
