Operation Instruction

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.
