1.5 Precautions
1.
We strongly recommend you to enroll at least one administrator after installing the
fingerprint lock. You must enroll at least one administrator before enrolling ordinary
users.
2.
Do not remove batteries when matching, enrolling or deleting fingerprints because
the sudden power-down may result in data loss of fingerprint locks. Prior to
removing batteries, make sure the fingerprint lock is not in working state.
3.
It is recommended to replace the fingerprint lock batteries at least once every six
months to avoid damaging the circuit due to the battery leakage. Do not use batteries
with poor quality.
4.
When installing a fingerprint lock, connect the plug to the socket properly.
Improper connection may lead to fingerprint lock failure.
