• Door Type: Suitable for standard wood doors.

4.2 Deadbolt Compatibility

If your existing deadbolt is positioned above the door handle, the Colosus NDL302 must be installed on the bottom. This is because the NDL302 unit is too long to be installed below a deadbolt in that configuration.

4.3 Handle Reversibility

The handle is reversible, making it suitable for both left-handed and right-handed door configurations. Refer to the detailed installation guide for instructions on how to adjust the handle direction if needed.

5. Operating Instructions

The Colosus NDL302 offers four convenient ways to unlock your door.

5.1 Unlocking with PIN Code

1. Activate the keypad by touching it. The numbers will illuminate.
2. Enter your programmed PIN code.
3. Press the '#' key to confirm.
4. If the code is correct, the lock will disengage. If incorrect, the keypad will flash red.

6.2 Cleaning

Clean the lock's exterior with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish or electronic components.

7. Troubleshooting

• Incorrect Code Entry: After 3 consecutive incorrect entries, the door lock will temporarily disable itself and trigger a beep alarm for 5 minutes. Wait for the lockout period to end before attempting to enter the code again.
