unlock your telephone, you must remember the 3 digit long “password” that you enter when you lock it. You will
need this to unlock your telephone. You can create any 3 digit code to lock your station, but the code to unlock it
MUST be the one that you used to lock it!
To lock or unlock your station:
Press PGM.
Dial 9.
Enter your 3 digit “password.”
Press SAVE.
Your telephone is now locked.
To temporarily unlock your station (This will allow you to make one telephone call. Then it reverts back to a locked
state):

Your telephone will revert to the locked state when you hang up.
