1. In factory default, all the fingerprints can be used.
2. Register fingerprint: shortly press SET button, then hear sound “DA, DA”. Place fingerprint on the fingerprint recognition window, hear “Di—”long beep, and this means adding fingerprint successfully.

Warmly note: to get the best effect, kindly suggest registering fingerprint 3 times at different area by using the same fingerprint.
