4.1 Routine Operation Indications
User operation success indication: The buzzer sounds once and the green LED
indicator is solid on for 3 seconds.
User operation failure indication: The buzzer sounds short tone twice and the red
LED indicator is solid on for 3 seconds.
Warning indication: The buzzer sounds short tone five times intermittently.
4.2 Administrator Loss Prevention
To avoid the menu operation failure as a result of loss of administrator, you may take
the following measures: Press and hold the Menu key for 3 seconds to display the
administrator verification interface. Then move the band switch on the rear of the
fingerprint lock to the left or right. Now you can access the menus as super
administrator for management and operation.
4.3 Battery Low Voltage Protection
Low Voltage Protection: When the battery meter stays at one bar, the system
prompts you to replace the battery and the battery icon starts flashing. If you press
and hold the Menu key, the system prompts you that you cannot access menus. In
addition, the menus are also inaccessible during use of external power so as to
prevent data loss caused by power instability. When the battery meter stays less than
one bar, the battery shuts itself off automatically.
