Operating Instructions
1. Registering Fingerprints
The Gateman WF-200 can store up to 20 fingerprints. To register a fingerprint:
- Access the registration mode (refer to the specific sequence in your quick start guide, usually involving a master PIN).
- Place your finger on the Easy Scan sensor.
- Follow the voice prompts to lift and place your finger multiple times until registration is complete.

Your fingerprint is the key. The image shows a finger being placed on the fingerprint scanner for access.
2. Setting a PIN Code
To set or change your PIN code:
- Enter the master registration mode.
- Input your desired PIN code (4-12 digits recommended).
- Confirm the PIN code as prompted.
3. Using the Decoy PIN Feature
To prevent your PIN from being exposed, you can enter random numbers before or after your actual PIN. For example, if your PIN is 1234, you can enter 987612345432. The lock will recognize the correct sequence within the longer string.

The decoy PIN feature allows adding meaningless numbers before or after your PIN to enhance security.
4. Opening the Door
- By Fingerprint: Place a registered finger on the sensor. The lock will unlock upon successful recognition.
- By PIN Code: Touch the keypad to activate, enter your PIN code (with or without decoy numbers), and press the '*' or '#' button (refer to specific model instructions).
- By Mechanical Key: In case of emergency or battery depletion, use the provided mechanical key.

The lock supports both fingerprint and PIN code entry for convenient access.
5. Locking the Door
- Automatic Locking: The lock will automatically engage after a few seconds once the door is closed.
- Manual Locking: Press the lock button on the exterior unit or use the manual lock switch on the interior unit.
6. Child Safety Button
The child safety button, located on the interior unit, prevents accidental opening from the inside. When enabled, the button must be depressed before the handle can be operated.

The child safety button on the interior unit requires activation to operate the handle, preventing unintended exits.
7. Double Lock Feature
To activate the double lock feature for enhanced security and privacy, engage the specific switch on the interior unit. When double lock is active, all external access methods (fingerprint, PIN) are disabled.

The double lock feature blocks all external access for increased security and privacy.
Maintenance
1. Battery Replacement
When the low battery indicator appears or voice prompts indicate low power, replace all batteries with new AA alkaline batteries. Do not mix old and new batteries or different battery types.
2. Cleaning
Clean the lock's exterior with a soft, dry cloth. Avoid abrasive cleaners, solvents, or excessive moisture, which can damage the finish or electronic components. Regularly wipe the fingerprint sensor to ensure optimal performance.
3. Clearing Fingerprints from Pad
To clear residual fingerprints from the keypad surface, simply touch the entire pad with your palm for a few seconds. This helps maintain privacy.
