About Handset

ISAT Phone-2 will be supplied by BSNL to customers on first come first serve basis
The more sky you can see the stronger the signal should be from the satellite. If open sky makes up about 70% of your view when you look up, then the signal should be strong. Searching satellite will appear on the screen. When your phone is connected to the satellite, the screen will display Ready for service. The top left of the screen will display Inmarsat.

The signal bars indicate the signal strength. At least two signal bars are required to make and receive calls.
If the received signal strength falls during a call, as shown by the signal strength indicator, ensure that the antenna is pointed towards the satellite and there are no obstacles between you and the sky. The e-Compass is displayed to indicate the direction in which the antenna should be maintained. When you return the handset to your ear, ensure that you keep it pointed in the direction of the satellite.
Before you can make a call, your phone needs a GPS fix so it can be located by the satellite. This happens automatically but if a new GPS fix is needed, the GPS fix icon will be displayed. Keep the phone in the open with a clear view of the sky until the icon disappears. Your phone is now ready to make and receive calls.
