How to apply an emergency power supply
How to replace batteries
When the battery voltage is insufficient, and
the door cannot be opened from the outside,
you can power up the lock through the Micro
USB interface by using a 5V power bank as
an emergency power supply. After opening
the door lock, please replace the batteries
immediately.
The lock is powered by four 1.5V alkaline
batteries. The battery cabinet is located
at the upper part of the inside escutcheon.
Push the battery cover upwards to remove
the batteries.
