Frequently Asked Questions
Q: How do I turn on the illumination for the control elements?
Touch the top-middle of the cover to trigger the proximity switch, which turns the lighting on for about 20 seconds.
Q: What should I avoid doing right after turning on the 12 V power supply?
Don't touch the cover while it's calibrating - the sensor electronics take a few seconds to calibrate themselves once the 12V supply is connected.
