m70L Installation & Configuration Guide
Manual Backlight Control
This mode is useful when the m70L is in a room with no outside windows and
unchanging ambient light levels.
1
Set
the
BACKLIGHT
CONTROL
MODE
to
MANUAL
.
2
Adjust the
BACKLIGHT
INTENSITY
to a comfortable brightness. A lower brightness
will increase backlight life.
Caution:
Changing a failed backlight is a job for a qualified service technician. It is done at
the factory, not in the field. Contact your Planar dealer for more information.
Auto Backlight Control
1
Set the
BACKLIGHT
CONTROL
MODE
to
AUTO
.
2
Set the
AMBIENT
THRESHOLD
to an ambient light level at which the backlight
changes intensity. If the current
AMBIENT
LIGHT
(shown on the bottom line) drops
below the threshold, the backlight dims; if it rises above the threshold, the
backlight brightens.
Note:
Ambient light is a relative value, and is pertinent only to the m70L. It is not an absolute
value. You may get different ambient light values with a handheld light meter.
Note:
The m70L has a nominal time delay of three minutes before it changes light levels. This
time delay prevents flickering if the ambient light level is near the ambient threshold.
