When the battery is fully charged, the battery meter in the display shows
full and the indicator on top of the phone show a steady green light.
It is possible to use the phone while the battery is being charged; however,
the charging time is increased.
Disconnecting the Charger
1. Disconnect the charger from the electrical socket.
2. Press the button under the charger plug connected to the phone and
pull the plug out.
When to Charge the Battery
The Lithium Ion (Li-ion) battery that comes with your phone can be
charged as often or as long as you wish without losing performance. This
is not the case with the nickel cadmium type batteries, often sold as
accessories from other suppliers.
Important! For optimal talk and stand-by time, we recommend that you
use only Lithium Ion (Li-ion) batteries with your phone.
When the battery needs charging the following happens:
• an alarm signal (a long beep) sounds and the message ‘Battery low’
appears for ten seconds in the display.
• the indicator light on top of the phone starts blinking red.
Low Battery Alarm
When the battery has discharged, the low battery alarm sounds several
times, before the phone automatically shuts off. You might be able to turn
the phone on again, but you will not be able to make or receive any calls
until the battery is being charged or replaced with a charged one.
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.
