Step 1 - Open the Drawer: Turn the Outside Thumbturn Knob to the left (counter-clockwise) to clear it of entries. Enter your combination - the default combination set upon installation is buttons 2 and 4 pressed simultaneously, then 3. You should feel a slight click as each button is depressed. Turn the Outside Thumbturn Knob to the right (clockwise) to recess the Cam, then pull the drawer open using the spring-loaded handles.

Step 2 - Enter the Existing Combination: Follow the steps in 1, first clearing the entries by turning the Outside Thumbturn Knob to the left, which should cause the Cam to ascend. Enter your existing combination by pressing the appropriate buttons. Do not turn the Outside Thumbturn Knob. Combination cannot be changed if lock is in OPEN position.

Figure B: Remove Alan Screw from side of lock inside drawer.

Figure C: Gently insert allen wrench into hole to depress internal lockout slide.

Step 5 - Enter New Combination: Turn the Outside Thumbturn Knob to the left (counterclockwise) to the stop position, then release. Select your new combination and write it down in a safe location. Enter your new combination - press the buttons carefully. You should feel a slight click as each button is repressed.

Note: You can use one button or all five for a combination, but each button can only be used once. You can depress two or more buttons simultaneously as a step in the combination.

Step 6 - Set and test your new combination: Turn the outside thumbturn knob to the right (clockwise) to the stop position. Release. Your new combination is now active.

Test your new combination a few times before you shut the drawer.

Replace the allen screw before closing and locking your drawer.

Troubleshooting: If the outside thumbturn retracts the cam and you have not entered your combination, steps were done out of order and the lock is in zero code. Repeat steps 1 through 5 until the cam retracts only after you enter your new combination.

Note: The outside thumbturn knob cannot be forced to retract the cam because it is connected to the lock housing by a friction clutch. If the thumbturn has been forced, it can be turned back to the original position by hand without damaging the lock.
