Testing the Battery Power
To check the battery level, press and hold the '5' button on the keypad (3 seconds). The button from '1' to '4' will
glow GREEN or RED to indicate the battery level:
Remaining Battery Capacity Level
If 4 digits glow green: 80%-100%
If 3 digits glow green: 60%-80%
If 2 digits glow green: 40%-60%
If 1 digit glows green: 20%-40%
If 1 digit glows red: 2%-20%
If 1 blinks red: less than 2%
Low Battery
If '1' button on the keypad blinks 5 times and you hear a beep when opening the safe, your battery level is
critically low and your safe needs to be charged immediately.

A) all four of the white lights above the micro-USB jack are blinking or B) it takes more than 4 hours to recharge
the battery. (Refer to the "Battery Installation" section for instructions).
The adapter used to charge the battery should output 5V/1000mA or above the using micro-USB.
