Troubleshooting
1.
Fingerprint can not be read or it takes too long.
›
Check whether a finger or fingerprint sensor is stained with sweat, water, or dust
›
Retry after wiping off finger and fingerprint sensor with dry paper tissue or a mildly
wet cloth.
›
If a fingerprint is way too dry, blow on the finger and retry.
2.
Fingerprint is verified but authorization keeps failing.
›
Check whether the user is restricted by group or time zone.
›
Check with administrator whether the enrolled fingerprint has been deleted from the
device for some reason.
3.
Authorized but door does not open.
›
Check whether the lock open duration is set to appropriate time, which opens the lock.
›
Check whether anti-passback mode is in use. In anti-passback mode, only the person
who has entered through that door can exit.
4.
Why device display “system broken“ and the alarm is ringing.
›
Check whether the device and back plate are securely connected to each other. If not,
a tamper switch is activated which triggers the alarm and keeps it ringing.
