Your device

To deactivate the flight mode, select any other profile.

In the flight mode you can make an emergency call. Enter the emergency number,

press the call key, and select Yes when asked Exit flight profile? The device

attempts to make an emergency call.

When the emergency call ends, the device automatically changes to the general

profile mode.

■ 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 device. When you end or reject

the call, the keypad automatically locks.

When the keyguard is on, calls still may be possible

to the official emergency number programmed into

your device.

■ Functions without a SIM card

Several functions of your device 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 device.

■ Access codes

The security code (5 to 10 digits) helps to protect your device against

unauthorized use. The preset code is 12345. To change the code, and to set the

device to request the code, see Security p. 50.
