Frequently Asked Questions

Q: How do I turn on the illumination for the control elements?

Touch from above on the middle of the cover to activate the proximity switch, which turns on the lighting for approximately 20 seconds.

Q: What should I avoid doing right after turning on the 12 V power supply?

Do not touch the cover during calibration, as the sensor electronics calibrate themselves for several seconds after the 12 V power supply is established.
