If the blinking doesn't stop after approximately five minutes, reset the handset power and reattempt network registration three times.
If this fails, try using the Manual Search mode in a good coverage area for up to 30 minutes.
If you still face the same problems after these steps, perform a GPS Current Position test for 15 minutes by selecting the Navigation menu and the ‘Current Position’.
Note: Mobile Satellite handsets require a clear view of the sky. If you are inside a building, tunnel or other structure that limits your view of the sky, the satellite signals may be weak or unavailable.
