Locking the Phone

You can lock most Nokia phones (this is much more restrictive than locking the keys) by tapping the Power button, choosing "Lock phone" from the menu, and entering the lock code. Once the phone is locked, you can perform only two actions:

• You can tap the left soft key, which is labeled Unlock on the screen, and enter the lock code again to unlock it. If you are in the dark, tap the Power button to turn on the LCD backlight.
• If there is an incoming call, the locked phone will ring and you can take the call by pressing the green Call button.

If you just want to lock your keypad to prevent accidental dialing (or launching applications) when the phone is in your pocket, you can press the left soft-key and the * key at the same time. To unlock it, just press the left soft-key (or middle soft-key on devices with three soft-keys) and the * key again. No password is needed. Accidental dialing is especially a problem for phones that have the navigation pad sticking out like a joystick (e.g., the Nokia 6600).

You cannot dial any phone number or execute any application when the phone is locked. The default lock code in a factory-fresh phone is 12345. You can change the lock code in the Settings Security Phone and SIM Lock code menu on a Series 60 device or the Settings Security settings Access codes Change security code menu on a Series 40 device. On earlier Nokia Series 60 devices, you might find those settings in the Tools program rather than the Settings program.

Using the security settings, you can also configure the phone to automatically lock itself after a period of time .
