Operation
To operate the fingerprint reader, only
the one-time laying on of the previously
taught-in finger is necessary.
The LED lights up red when the finger is laid on. During
this time the fingerprint is read. After the short acknowl-
edgement tone, the finger can be removed. While the fin-
gerprint is being compared to saved fingerprints, the LED
lights up orange. If the finger is recognised the LED lights
up green and a long acknowledgement tone is heard
(positive acknowledgement signal). At the same time the
previously specified switching action is executed.
An unauthorised or unassigned finger is indicated with a
red LED and 3 short acknowledgement tones (negative
acknowledgement signal).
i
360° contact surface for finger
Taught-in fingers are detected in any

optimum positioning of the finger (see
graphic) is preferable.

Acknowledgement tones can be switched off
