2.2. Door Preparation and Dimensions

2.3. Adjusting Handle Direction
The handle direction can be adjusted for left or right-handed doors. The lock is initially set with handles facing upwards. To change the direction:
- Locate the cross hole on the back of the lock panel.
- Use a small screwdriver to loosen the internal screw.
- Adjust the handle to the desired left or right direction.
- Tighten the screw to secure the handle direction.
For the back panel, if the front door handle is set to a right-hand orientation, the back panel handle should be adjusted to a left-hand orientation, and vice-versa, to ensure proper operation.

2.4. Setting a Passcode
The lock's passcode is set mechanically. The original mode has no password, allowing the handle to be pressed freely. To set a password:
- On the back of the keypad panel, observe the 'fish eyes' indicators. If all 'fish eyes' face inwards, there is no code set.
- To set a password, press down on the desired number's 'fish eye' with a screwdriver and rotate it 180 degrees so it faces outwards (towards the number).
- Repeat for all numbers you wish to include in your passcode. A 4-7 digit combination is recommended for security. The 'C' button cannot be part of the combination.
- The same process applies to both the front and back keypad panels if you desire different codes for each side.
Important: Passcodes can be entered in any order. Always press the 'C' button before entering the code to clear any previous entries.
