1. Turn the interior knob to the OFF position (Privacy Mode).
2. Press the settings button once with the provided pin.
3. The administrator must first verify their fingerprint once.

5.4 Privacy Mode (Back Locking Function)

When Privacy Mode is activated, only administrators can unlock the door from the outside. Ordinary users cannot unlock it, increasing security performance.

• To activate: Rotate the thumb turn on the interior knob to the OFF position.
• To deactivate: An administrator's fingerprint can unlock it, or rotate the thumb turn to the ON position.

5.5 Passage Mode

In Passage Mode, the door remains unlocked, allowing free entry and exit without fingerprint verification. Use with caution.

• To activate: The administrator's fingerprint does not move on the collector. The indicator light of the fingerprint collector lights up pink and emits 10 beeps, indicating the passage mode is turned on.
• To deactivate: Administrators and users can close the passage mode by pressing the collector with their fingerprints and hearing 10 beeps. The door lock will then return to its normal state.
