Calibration
When it is delivered, the knob is calibrated so that the user scenarios listed above can be carried out. If these do not work
(for example if the cylinder is installed upside-down), you can recalibrate the knob after mounting it.
This requires the following actions:
1. Mount the cylinder on the door.
2. Press the button on the cap of the knob for 20 seconds until you hear three beeps.
3. Then lock the cylinder again and pull out the key.
4. After a two-second continuous tone, the cylinder is recalibrated.
Note: Calibration has no effect on the cylinder's direction of rotation. This is defined using DIP switch 3.
