2Adjust 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.

2Set 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.
