Troubleshooting
This chapter tells you what to do if you experience one of the following
problems:
Problem Solution
You can’t turn the
phone’s power
on.
• Did you press and hold the S key for three seconds
to turn the phone’s power on?
• Check the battery. Is it charged, properly fitted, and
are the contacts clean and dry?
You can’t make
calls.
• Check the antenna. Is it fully extended and rotated?
Do you have a clear unobstructed view of the sky?
• Did you enter the number in international format? All
calls made from the Iridium satellite system must be
in international format (in satellite mode only).
• Check the signal strength indicator. If the signal is
weak, move to an open space or, if you are in a
building, move closer to a window.
• Check the Network Selection settings. Try to register
manually in satellite mode. In GSM cellular mode, try
a manual search and select another network.
• Check your operator coverage map.
• Is Restricted displayed? Check the call barring
setting.
• Has a new SIM card been inserted? Check that no
new restrictions have been imposed.
• Check to see if your fixed dialing list is enabled. If so,
you can only make calls to numbers or prefixes that
are on the list. To make calls in cellular mode, you
must disable this feature from satellite mode.
