After the fingerprint is passed, the OUT1 pin outputs a signal with
a voltage of 3.3V and a current of 500ma for 1 second. In the
initialization state, any fingerprint can pass through.
1. Register Fingerprint: Long press the registered fingerprint(In initial state press any
fingerprint), until the blue indicator light turn on and hearing
music, means the system in register state, press the finger with
multiple times in fingerprint collection area,each press have "di"
sound, until hearing music means fingerprint register successful.
Fingerprint can be registered continuously when system in register
state; if no need adding fingerprint more, waiting a few seconds.
Note: In the initialization state,must have to register more than 2
correct fingerprints for the first time,then the system can be
removed from the initialization state.
2. Delete Fingerprint(Back to initialization state):
2.1 Long press the registered fingerprint, until the red indicator
light turn on,means all fingerprints are deleted and back to
initialization state.
2.2 Use INIT_KEY pin. In the standby state, make the INIT_KEY pin
ground connection, until the red indicator to turn on, hear the
"Di-" sound, disconnect the grounding, the indicator turns green,
means all fingerprints are deleted and back to initialization
state.
