Re Model 06037MA1, I want display to go dark except when I want to see it. But I don't see any way to accomplish that other than to unplug it. And instructions say don't unplug it. Tell me how to make it go dark, please. Leaving it on all the time will ruin the display.
There is no way to turn off the display. You can run it on battery power only if you would like. You would press the backlight button each time you want the backlight to come on. It would come on momentarily for about 7 seconds and then go off. For optimal use we do recommend that you keep the display plugged in.
