Operating Instructions
Unlocking with RFID Card
To unlock the furniture lock:
- Present a registered RFID card to the designated card reading area on the lock unit.
- The lock will emit an audible signal (e.g., a beep) and/or a visual indicator (e.g., a green light) to confirm successful card reading.
- The lock will disengage, allowing you to open the cabinet or drawer.
Automatic Locking Function
The OZFL-33 RF features an automatic locking function. After the cabinet or drawer is closed, the lock will automatically engage after a short delay (typically a few seconds) without requiring card presentation.
RFID Card Programming
This section details how to register and manage RFID cards for your lock. The lock can register up to 30 RFID cards.
Registering New RFID Cards
- Enter Programming Mode: Locate the programming button (often inside the lock unit or battery compartment). Press and hold this button until the lock indicates programming mode (e.g., a specific light pattern or sound).
- Present Master Card (if applicable): If your lock uses a master card, present it first to authorize programming.
- Present New Card: Present the new RFID card you wish to register to the card reading area. The lock will confirm successful registration (e.g., a beep).
- Register Additional Cards: Repeat step 3 for any other cards you wish to register.
- Exit Programming Mode: Press the programming button again or wait for the lock to automatically exit programming mode.
Deleting RFID Cards
Consult the specific instructions provided with your lock for deleting individual cards or resetting the lock to factory defaults, which typically clears all registered cards. This process often involves entering programming mode and following specific sequences.
Maintenance
Battery Replacement
The lock features a low battery indicator. When the battery is low, replace it promptly to ensure continuous operation.

USB for Battery Backup
In case of complete battery depletion, the lock may feature a USB port for temporary power supply, allowing you to unlock it and replace the batteries. Connect a standard USB power source to this port to activate the lock.
