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, please
replace the batteries immediately.
In case of a system crash and it's
impossible to open the door from outside,
please press the [RES] button and then
release it to reboot automatically.
The lock is powered by four 1.5V alkaline
batteries. There are two sets of working
power stations in the battery cabinet. Eight
batteries can put in to extend battery life
and reduce battery replacement frequency.
The battery cabinet locates at the
bottom end of the inside escutcheon.
By pushing the cover upwards, you can
remove it and replace the batteries.
