The backlight requires extra power to operate.
To extend battery life, keep the display
backlight off or use the “lo” setting.
The contrast setting changes the contrast of
the display. Use the left and right arrow keys
to adjust the contrast. The best setting is
determined by available light conditions and
the visual angle at which you view the display
when you use the receiver. (You may also
change
the contrast by pressing the
MENU/PWR key and the right or left arrow.
See the inside front cover.)
