Troubleshooting
When you turn on the keypad, if the keypad’s LCD shows
abnormal or nothing, check your battery first. If the battery is
working fine, try to find an acicular metal and plug into the reset
hole (at the back of the keypad). Then the keypad will work
normally. If the problem was still unsolved, please contact the
technical support.
