3. CAUTIONS ON HANDLING
• Cleaning the cabinet
Use a soft, dry cloth to gently wipe off dirt.
For tough dirt, apply some neutral detergent
diluted in water to a soft cloth, wipe off the dirt
gently, then wipe again with a dry cloth.
Do not use benzine, paint thinner, car cleaner,
etc., as these substances may damage the
cabinet or cause the paint to peel. Also,
leaving rubber of plastic products in contact
with the cabinet for long periods of time may
cause stains.
• Cleaning the LCD panel
The LCD panel tends to collect dust, so wipe
it off occasionally with a soft, dry cloth.
The surface is easily scratched, so do not rub
it with hard objects.
CAUTION
For a longer service life, be sure to read the following cautions
• Do not disconnect the control box and display unit during use. Also, be sure to turn the
power OFF before disconnecting the display unit.
• Don’t allow any liquids on the set from drinks, umbrellas, etc. Doing so may damage the internal
circuitry.
• Do not disassemble or modify the set in any way. Doing so may result in damage.
• Do not let cigarettes burn the display. Doing so may damage or deform the cabinet.
• If a problem should occur, have the set inspected at your store of purchase.
• Do not hold on the LCD panel when adjusting the angle of the LCD panel. Doing so may damage it.
Precautions on handling of the LCD panel
• Do not leave the monitor on the dashboard with the LCD panel facing upwards. (Range of storage
temperature: –20°C to +80°C)
When the temperature is high or low, chemical changes occur in the LCD panel, resulting in damage
to the monitor.
• Since the LCD panel has been specially processed, fingerprints will remain on the panel and stand
out if you touch the panel. Avoid touching the panel as much as possible. Also avoid pushing the
panel.
• When the temperature becomes low, the picture does not appear or sometimes it takes time to
appear. On occasion, picture motion seems to be different from that at normal temperature and the
picture quality deteriorates. These phenomena are not a malfunction. (Range of operating
temperature: 0°C to +40°C)
• On the panel red dots, blue dots and green dots are found. This is peculiar to the LCD panel and it is
not a malfunction.
[The LCD panel has been designed and manufactured using highly developed precision technology
and has 99.99 % or more effective pixels. However, note that 0.01 % of pixels are defective and
always light.]
