With Lock now selected, you must enter your lock code before the device can
function normally.
Call not allowed is displayed if you attempt to place a call with your device locked.
To answer a call with the phone lock on, select Answer, or press the call key.
Allow numbers
With the phone lock on, the only outgoing calls you can make are to the
emergency number programmed into your device or the number stored in the
Allowed no. when phone locked location:
1. Select Menu > Settings > Security.
2. Enter the lock code, and select OK. See "Change lock code," p. 37.
3. Select Allowed no. when phone locked. With an empty folder selected, select
Assign, and enter the phone number; or select Assign > Find to recall the
number from your contacts list. Select OK.
To call the allowed phone number, scroll down to highlight the number you want
to call, or enter it on the keypad; press the call key to place the call.
Change lock code
To ensure the security of your device, you may want to change the preset lock code
to your own selected four digit number. Avoid using codes similar to emergency
numbers to prevent accidental dialing of the emergency number.
With the wrong lock code entered five times in succession, your phone will not
accept your correct lock code for 5 minutes, even if you power off the device
between incorrect entries.
1. Select Menu > Settings > Security.
2. Enter the lock code, and select OK.
3. Select Change lock code.
4. Enter the new lock code (must be 4 characters in length).
5. Reenter the new lock code for verification, and select OK.
When changing your lock code, make sure you store it in a safe place, away
from your device.
Call restrictions
Select call restrictions to block or allow numbers for incoming and outgoing calls.
With any numbers entered as allowed numbers, all those entered as blocked
numbers are ignored. With a number blocked, the phone blocks any call from it,
and sends the caller to the voice mail.
