2. With the safe or container open, extend the lock bolt fully.
3. Wait ten seconds, then insert the change key into the receptacle in the lock cover.

right about ten numbers. The lock will emit three quick beeps.
8. Turn the dial left (counterclockwise) at least two revolutions, then stop when the first number of the 2
nd
existing dual user
combination comes to the opening index.
9. Turn the dial right (clockwise), stopping when the second number of the 2

index.
10. Turn the dial left, stopping when the third number of the 2

11. Turn the dial right (clockwise). As you begin to turn the dial, the lock will sound three quick beeps.
12. Turn the dial left at least two complete revolutions, then stop when the first number of the NEW single user combination comes to
the index.
13. Turn the dial right (clockwise) until the second number of the NEW single user combination comes to the index.
14. Turn the dial left until the third number of the NEW single user combination comes to the index, then turn the dial right until the
lock sounds three quick beeps.
15. Turn the dial left (counterclockwise) at least two full revolutions, then stop when the first number of the NEW single user
combination comes to the index.
16. Turn the dial right (clockwise) until the second number of the NEW single user combination comes to the index.
17. Turn the dial left until the third number of the NEW single user combination comes to the index. Then turn the dial right, and the

Do not close the safe door or container drawer until you have checked the new combination for proper operation at least
three times with the door or drawer OPEN. If necessary, refer to page 3 for single user operating instructions.
