2.4 Getting started
2.4.1 PIN (Personal Identification Number)
If the software access to the SIM card is protected, the device prompts you to enter the PIN.
Enter the code between 4 and 8 digits given to you when the SIM card was issued.
These digits do not appear on the screen for security reasons.
If there are contacts saved in your SIM card, you are invited, if you wish, to copy them in the phone contacts
memory.
Warning: if a wrong PIN is entered three times in a row, your SIM card is blocked.
You must then:
1. Enter the PUK [Personal Unblocking Key] provided by your operator, and validate.
2. Enter your PIN and validate.
3. Enter your PIN again and validate.
After 5 or 10 failed attempts [depending on the type of SIM card], the SIM card is definitely locked. You
must then contact your operator to obtain a new card.
2.4.2 Switching on/off (Red key)
When your phone is off, a short press on the red key will turn it on.
When you are in the idle screen, a long press on the red key will switch off the phone.
