When the battery voltage is insufficient, and the
door cannot be opened from the outside, you can
power 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. There are two sets of working power
inside the battery case. Eight batteries can be put
in to extend the battery life and reduce battery
replacement frequency.
The battery case is located at the upper end
of the inner unit. By pushing the battery cover
upwards, you can remove the battery cover and
then the batteries.
