Entering Your PIN Code

The SIM card is protected by a PIN (Personal
Identification Number) that you must enter the first
time you use your phone or each time it is switched
on, if this option is set (see page 50).
• For more details about the PIN and PUK codes, refer to the
glossary on page 77.
• If you wish to change your PIN, see page 51.
• If you enter the wrong PIN three times in a row, the
card is blocked. To unblock your phone, you must enter the
eight-digit PUK (PIN Unblocking Key) that comes with your
SIM card.
• If you enter the wrong PUK ten times in a row, your
SIM card will be permanently blocked. You must then
contact your network operator.

Extending the Antenna

If the signal received is weak (crackling and back-
ground noise during a telephone conversation), you
can pull out the telescopic antenna.
1. Grasp the knob on the end of the
antenna and carefully pull the
antenna out to its full extension.
Result: Reception quality is improved.
2. When you have finished the
conversation, push the antenna gently
back in.
If the signal received is sufficiently
strong, you do not need to pull out
the antenna.
The signal strength is indicated on
the display:
Strong signal
