About locking the radio
You can lock your radio to prevent unauthorized use, if 
this feature is programmed for your radio. When your 
radio is locked, you can only make emergency calls. 
Your radio can still receive calls and status requests, but 
you must unlock the radio to respond to them.
Your radio will remain locked even if it is turned off and 
then on again.
Locking the radio
You may be able to lock your radio by either turning it 
off and then on again, using the menu or by pressing a 
function key.
Security lock on power-up feature
Your radio may be automatically locked each time it is 
powered-up. The message 
Enter PIN appears in the 
display.
Using the menu to lock the radio
1 Press Menu and select Radio settings > Functions 
> 
Lock radio. (Depending on how your radio is 
programmed, you may be able to press a function 
key to turn radio lock on and off.)
2 Scroll to either On or Off and press Select. (The 
current setting is highlighted.)
The radio is now locked and the message Enter PIN 
appears in the display.
Unlocking the radio
■ To unlock your radio, use the unlock sequence you 
have been given. (This is a pre-programmed 
sequence of four keys.)
The radio remains locked until the correct sequence of 
keys is pressed. If you forget the unlock sequence or you 
do not know it, contact your radio provider for assistance.
