Precautions of System Operation
If the fingerprint verification fails, the red LED is on and there are four
buzzing sounds. Please check whether the fingerprint has been registered or
whether the finger has pressed correctly on the prism, then try again.
After the system is started, if there are eight consecutive buzzing sounds,
the batteries are low and should be changed as soon as possible.
If the door is not closed within 30 seconds after it is opened, there will be
an alarming buzzing sound at every 5 seconds interval.
