Fingerprint entry process: A. Press and hold your fingerprint for 5 seconds until the blue light turns on B. After verifying with the administrator's fingerprint, the blue light is on and the user's fingerprint can be entered. The fingerprints need to be entered 5 times. The blue light flashes when the fingerprint is entered, indicating that the entry is successful each time, and the red light flashes that the entry failed. After entering 5 passes, the blue light flashes 2 times in succession, indicating that the entry is successful, and the indicator light goes out immediately. In this cycle, 40 fingerprints can be entered. After the setting is completed, please test the authorized fingerprint for unlocking operation.
