The Antenna
Your phone is equipped with two antennas, a satellite communication antenna folded on the left side and an internal GSM antenna.
Deploying the Antenna
When the phone is used for Satellite communication the antenna must be rotated to the appropriate position for either right or left hand operation, as shown below. A third position is provided for operation on a flat surface with a ‘hands free kit’. Ensure the antenna clicks into position, is vertical at all times and has a clear view of the sky when in use.
You do not need to deploy the antenna to make a GSM call. The GSM antenna is internally mounted. Do not hold either antenna when the phone is IN USE. Holding the antenna affects call quality, may cause the phone to operate at a higher power level than needed and shorten talk and stand- by times.
