4.2 Unlocking a Locked Phone
If the locking feature is enabled, the phone automatically locks after a configured period of time,
securing it against unwanted (mis)use. If left untouched for 10 minutes (default), it automatically
locks and is inaccessible to anyone who doesn't know its lock code. After a phone locks:

Outgoing calls cannot be made

Call Log, Calendar and Corporate Directory cannot be accessed
Your network administrator if necessary can allow making emergency calls and other capabilities
even though the phone is locked. See the next section for more information.

To unlock a locked phone:

When prompted for a lock code, enter a code, e.g., 123456 , and then press OK ; the phone
enters idle state.


To manually change the code:
1. Press the MENU key on the phone, select Settings and then scroll down to select Device
Security .
