3. Setting your combination
WARNING: Improperly setting the combination is not covered under the warranty. Do not disassemble the
lock. Doing so voids the warranty.
3.1. Press on the CLEAR to reset the combination lock. (See Figure 3)
3.2. It is not necessary to remove the latch cover on the back of the latch mechanism. A window has been provided in
the face of the latch cover to allow for easy changing of the combination code. Simply open the lid and locate the
latch cover combination window.
3.3. Looking at the rear of the pushbutton combination lock from the inside of the box you will see ten numbered
buttons with arrows. (These are actually upside down the way the latch is installed) These numbers correspond
to the numbered button on the front of the lock. (See Figure 4)
3.4. The arrows on the screws are pointing in the direction which the previous codes were set to. (See Figure 4)
IMPORTANT: Open knob must be in LOCKED position before the code can be changed.
3.5. Use a small screwdriver to rotate the arrows. For each number in your combination, apply light pressure and
rotate a half turn so that the arrow points correctly (SET ON) and snaps up. Be sure to reset all the arrows to
SET OFF before entering the new combination. (See Figure 4)
3.6. Check to make sure that the arrow of any number that is not in the combination is pointing the correct direction
(SET OFF). (See Figure 4)
CAUTION: Arrows must point either direction (SET ON or SET OFF). An arrow pointing differently indicates
that it has not snapped up, the combination will not work. Test the combination before locking the lid.

4. Testing your combination before closing the lid.
Please note: This product is equipped with a clutch mechanism to protect it from forced entry. Do not be
alarmed if the OPEN lever turns even if the correct combination has not been entered.

4.3. Turn the OPEN lever clockwise to disengage the latch mechanism. When the latch mechanism disengages it will
spring back open again. If you have entered an incorrect combination, you can return the buttons to their original
setting by shifting the CLEAR lever. (See Figure 3)
4.4. When you turn the lever, the combination will clear. (See Figure 3)
4.5. To relock the combination lock turn the OPEN lever counter-clockwise. (See Figure 3)
