Warning: With the flight profile you cannot make or receive any calls,
including emergency calls, or use other features that require network
coverage. To make calls, you must first activate the phone function by
changing profiles. If the device has been locked, enter the lock code. If you
need to make an emergency call while the device is locked and in the flight
profile, you may be also able to enter an official emergency number
programmed in your device in the lock code field and select ‘Call’. The device
will confirm that you are about to exit flight profile to start an emergency call.
To deactivate the flight mode, select any other profile.
Note: In the flight profile, you may need to unlock the device and change to the
calling profile before making a call.
Keypad lock (keyguard)
Select Menu or Unlock (1), and press * (2) within 1.5
seconds to lock or unlock the keypad.
If the security keyguard is activated, enter the security
code if requested.
To answer a call when the keyguard is on, press the
call key or open the phone. When you end or reject the
call, the keypad automatically locks.
For Security keyguard, see "Phone," p. 45.
When the keyguard is on, calls may be possible to the official
emergency number programmed into your phone.
Functions without a SIM card
Several functions of your phone may be used without installing a SIM card (for
example, the data transfer with a compatible PC or another compatible device).
Without a SIM card, some functions appear dimmed in the menus and cannot be used.
For an emergency call, some networks may require that a valid SIM card is properly inserted
in the phone.
Access codes
Security code
The security code helps to protect your phone against unauthorized use. You can
create and change a code, and set the phone to request the code. See "Security," p. 46.
