FAQ - Frequently Asked Questions
What happens if the battery starts to run out of power
When the internal battery starts to run out of power, the Biometric fingerprint door lock will provide you with a warning every time you use it
What happens when the battery dies and I get locked outside
There is a 9V battery connector located below the door knob at the bottom frame of the unit, a simple connection using a 9V battery will bring it back to life. This unit can also be connected to a permanent power supply, so you never have to worry about recharging the internal battery. Please consult the User manual and the installation video provided in the CD ROM
Is the CVKY-BG06 Waterproof?
No, the unit is weatherproof but not waterproof. Meaning any outside door that is in a well covered area where there will be no direct rain or snow contact is acceptable, but the unit can never be directly exposed to constant water contact.
