·LED can off in sleep mode: long press (about 10s) the SET button, LED will be off in sleep mode.
K215-V1.3 Circuit board diagram
K215-V1.3 Reference Connection Diagram:
1. Press SET button shortly,system in register state and blue indicator light flash fast, place your finger in the collection area, fingerprint register successful when hearing music;Fingerprint can be registered continuously when system in register state; if no need adding fingerprint more, waiting a few seconds.
2. When back to factory default, press SET button until hear “Di” and music,means initialization operation successful.
3. Mode Selection Usage: when chose 2, operating time of the relay is 1s-20s after pass fingerprint,can adjust by knob. When chose 1, relay operated when fingerprint passed, and then relay released when fingerprint passed again, relay operated and released circularly. Relay released when power off.
●In factory status, any fingerprint can pass, after register fingerprints, this function is invalid;
●Set sleep mode, long press (about 10s) the SET button and do not release your finger until hearing the "DiDiDi" sound and the music,means initialization operation successful.
