Operating Instructions
Initial Code Setting:
Upon first use or after a factory reset, the lock will have a default master code. Refer to the specific programming guide included with your lock for detailed steps on changing the master code and setting user codes. This typically involves entering a sequence of numbers followed by a confirmation button.
Private User Mode:
In Private User Mode, a single, fixed user code is used to operate the lock. This mode is ideal for personal use where the same user accesses the cabinet repeatedly.
- To lock: Close the cabinet door/drawer and enter your pre-set user code. The lock will engage.
- To unlock: Enter your pre-set user code. The lock will disengage.
Public User Mode:
In Public User Mode, users can set their own temporary code for a single use. Once unlocked, the code is cleared, and the next user can set a new code. This mode is suitable for shared environments like gyms or public lockers.
- To lock: Close the cabinet door/drawer, enter a new personal code (e.g., 4-6 digits), and press the lock button. The lock will engage.
- To unlock: Enter the code you set to lock the cabinet. The lock will disengage, and the code will be cleared.

Maintenance
Battery Replacement:
The lock is equipped with a low battery indicator. When the battery level is low, the indicator will activate (e.g., a specific light flash or sound). Replace batteries promptly to ensure continuous operation. Follow the battery installation steps outlined in the Setup section.
Cleaning:
Clean the exterior of the lock with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or internal components. Ensure no liquid enters the keypad or key cylinder.
