Operating Notes
Internal Fans
Internal cooling fans maintain proper operating tempera-
tures inside the TV. It is normal to hear the fans when you
first turn on the TV, during quiet scenes while viewing the
TV, and for a short time after turning off the TV.
TV Software
Do not attempt to update the software of this TV with
software or USB drives not provided by or authorized
by Mitsubishi Digital Electronics America, Inc. Non-
authorized software may damage the TV and will not be
covered by the warranty.
Cleaning Recommendations
Normally, light dusting with a dry, non-scratching
duster will keep your TV clean. If cleaning beyond this
is needed, please use the following guidelines:
First, turn off the TV and unplug the power cord from
the power outlet.
Top and Sides of the TV
• Occasionally clean dust build-up from the air-intake
grilles on the back and sides of the TV. Clean using
a vacuum cleaner with a brush attachment.
• Gently wipe down your TV with a soft, non-abrasive
cloth such as cotton flannel or a clean cloth diaper,
lightly moistened with water. Dry with a second dry,
soft, non-abrasive cloth.
• For oily dirt, add a few drops of mild liquid deter-
gent, such as dishwashing detergent, to the water
used to moisten the cloth. Rinse with a second
cloth moistened only with water. Dry with a third
dry, soft, non-abrasive cloth.
Screen
• Follow the instructions for the top and sides, wiping
gently in an up and down motion.
• Clean the entire screen evenly, not just sections of
the screen.
• Do not allow liquid to drip down the screen, as
some liquid may enter the TV through the gap
between the screen and screen frame.
• You may purchase Mitsubishi Screen Cleaner, part
number CLEANER-VSS, by calling (800) 553-7278.
General Cleaning Precautions
• DO NOT allow liquid to enter the TV through the
ventilation slots or any crevice.
• DO NOT use any strong or abrasive cleaners, as
these can scratch the surfaces.
• DO NOT use any cleaners containing ammonia,
bleach, alcohol, benzene, or thinners, as these can
dull the surfaces.
• DO NOT spray liquids or cleaners directly on the
TV’s surfaces.
• DO NOT scrub or rub the TV harshly. Wipe it gently.
IMPORTANT
DO NOT use any kind of abrasive cleaner on the
surface of the TV screen.
