After you've changed the combination:
Dial the new combination (see chart for dialing numbers) to be certain that combination has been properly changed.
If a mistake was made in following the above instructions, dial the first combination (see chart). If it does not work, dial the next combination, etc. until correct combination to open the lock is reached.
IMPORTANT: Make sure the combination change is reported to the lock supervisor so the records can be brought up to date.
