Hello all- newbie here: in my employer's home one of the multi-button keypads that controls 5 or so lights has a problem. No matter which button you push, all of the green leds flicker rapidly and nothing will come on. Is there some simple way of rebooting this particular keypad? The home is completely outfitted with this system and everything else seems to be working properly. This was installed approximately 4-5 years ago, and the installer has sudenly gone MIA. Any pointers? FWIW- Lutron "tech support" is of no use. Thanks.
