Operating the fingerprint scanner
The fingerprint scanner records the fingerprint via a line sensor and
evaluates it. It compares the image obtained with the biometric information
stored in the reference fingerprint. If these correspond, the door opens.
The fingerprint scanner only works correctly and reliably with the papillary
lines of the distal phalanx (1). Drag the finger smoothly and evenly over the
sensor as described below.
The finger guide on the fingerprint scanner serves to position the finger
correctly. It is the underlying operating element and consists of the sensor
(2) and the right (1) and left (3) guide edges.
Drag finger
Holding the finger straight, position it centrally between the guide edges.
Do not turn it.
Place the joint of the distal phalanx directly on the sensor. Place the finger
flat on the finger guidance.
Stretch out the fingers next to it.
