4. Operating Instructions
4.1. Initial Setup and Master PIN Code Registration
Upon first power-up, you will need to register a Master PIN Code. Refer to the included English manual for specific steps, as this is crucial for all subsequent programming.
4.2. Registering User PIN Codes
Follow the instructions in the manual to add up to 4 user PIN codes. Each user code should be unique and easy to remember for authorized users.
4.3. Registering Tag-Keys
The lock supports up to 30 Tag-Keys. To register a Tag-Key, enter programming mode (using the Master PIN Code) and follow the prompts to scan the Tag-Key.
4.4. Unlocking the Door
- Using PIN Code: Touch the keypad to activate, enter your PIN code, and press the '*' button (or equivalent confirmation button). Turn the lever to open.
- Using Tag-Key: Place the registered Tag-Key on the designated reader area. Turn the lever to open.
4.5. Locking the Door
- Automatic Locking: If Flex Lock is set to Automatic mode, the door will lock automatically a few seconds after closing.
- Manual Locking: If Flex Lock is set to Manual mode, press the '*' button (or equivalent lock button) on the keypad from the outside, or turn the thumb-turn from the inside.
4.6. Dual Lock Function
To activate Dual Lock, engage the specific mechanism on the interior unit (refer to the manual for exact location and operation). This prevents the lock from being opened from the outside, even with a valid PIN or Tag-Key.
5. Maintenance
- Battery Replacement: Replace all batteries when the low battery alert is activated. Use high-quality alkaline batteries. Do not mix old and new batteries.
- Cleaning: Clean the lock's exterior with a soft, dry cloth. Avoid abrasive cleaners or solvents that could damage the finish or electronic components.
- Regular Checks: Periodically check that all screws are tight and that the lock operates smoothly. Do not lubricate the internal electronic components.
