Network search

Most SIM cards are protected with a PIN (Personal Identity
Number), which you get from your network operator and
which you need in order to access the network.
If the SIM card is not protected by the PIN code then you do
not need to enter the PIN and the FCT starts automatically the
Network Search.
If the SIM card is protected by the PIN code, then the Green
and Red light indicators flash simultaneously.
Note: if you have the DA20 display adapter accessory (See
"FCT accessories" on page 41), an "Enter PIN" message will
show on your display.
Follow the following procedure to enter the PIN:
Pick up the telephone and dial the PIN code. Press the #
key on your telephone or wait until you hear a beep tone.
If you make a mistake while entering your PIN, hang up
immediately the telephone down and try again.
If the PIN is correct, you will hear a beep over the telephone
(affirmative indication tone). If it is incorrect, a loud and low
tone will sound (error indication tone).
If your PIN is entered incorrectly three times, the SIM card
will be blocked. If this happens, you can unblock it by using
your PUK (Personal Unblocking Key), which you also get
from your network operator. See "SIM Card Security" on page
32
Note: once you have entered the PIN code for the first time
you will not have to enter it again unless you change your SIM
card. The FCT performs this operation automatically in case
of power failure.
After you have switched on your FCT and entered your PIN,
the FCT automatically searches for a network.
Note: if the Red Light is off, there is a problem with the power
supply. See "Troubleshooting and FCT indicators" on page 34
