Change Combination in ComboGard Pro 39E Electronic Combination Lock

NOTE: Each combination must be changed independently at the Lock. New combination will not be accepted if it varies from the current combination by only one digit (+/-). When selecting a combination, do not use a birthday or other predictable information that could give correlation between the user and the combination.

CAUTION: Always perform this operation with the door open and test the opening of the Lock with the new combination several times before closing the door.

Steps to change combination

1. Enter existing combination and hold down last digit of combination until Lock double signals release and the LED stays on.
2. Press 0.
3. Enter the NEW combination.
4. Re-enter the NEW combination to confirm. The NEW combination is now active.
