Lock code
The lock code (5 to 10 digits) helps to protect your phone against unauthorized use. The preset code is 12345. Change the code, and keep the new code secret and in a safe place separate from your phone. To change the code and to set the phone to request the code, see “Security,” p. 73.

When the device is locked, calls may be possible to the official emergency number programmed into your device.
