Turning the Backlight On/Off

The display backlight can be set one of three levels (low, high or off).
The backlight causes severe drain on the batteries in the Meridian. To
prevent accidentally turning the backlight on and leaving it on, the Meridian
will turn the backlight off when there have been no buttons pressed for 4
minutes. Pressing any button will turn the backlight back on in this instance.
You can change the time delay for the backlight in Setup.
