Backlight Control
m40L/m46L Installation & Configuration Guide 73
Manual Backlight Control
This mode is useful when the m40L/m46L 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 lamp 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 On
If AUTO BACKLIGHT ON is checked, the display turns on the backlights soon after AC
power is applied. It won’t wait for a remote control or RS232 command.
This is the normal mode for applications where the displays will be on 24 hours a day.
This way, no one has to manually turn on the backlights after a power failure.
Caution: To prevent temporary image retention (TIR), is recommended that you do not
leave the m40L/m46L on for 24 hours a day. To get the most out of your display, see
"Recommended Usage" on page 6.
If the displays normally have the backlights off for part of the day or night, do not
check this box. Otherwise a power failure at night would turn on the lamps.
Turn Backlight Off With No Source and DPMS Delay
When checked, TURN BACKLIGHT OFF WITH NO SOURCE (DPMS) causes the backlights
to turn off if the source is absent for the length of time specified in the
DPMS DELAY
line. If this line is not checked, the backlights remain on indefinitely. To specify an
amount of time after which the source is absent that the backlights will shut off,
enter that number in the DPMS DELAY line.
