Troubleshooting
1. Fingerprint can not be read or it takes too long.
› Check whether a nger or ngerprint sensor is stained with sweat, water, or dust
› Retry after wiping o nger and ngerprint sensor with dry paper tissue or a mildly
wet cloth.
› If a ngerprint is way too dry, blow on the nger and retry.
2. Fingerprint is veried but authorization keeps failing.
› Check whether the user is restricted by group or time zone.
› Check with administrator whether the enrolled ngerprint 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.
