MSD600M - Technical Reference Manual
8. Precautions
Please observe the following guidelines for a
longer, trouble-free life for your MSD600M:
• Never operate the unit while opened, as the
high voltage (600V AC) applied to the LCD
background illumination is dangerous
• Avoid getting the unit wet or humid, since water
will create leakage currents on the PCB board
and may damage the circuitry
• As the LCD display and backlight elements are
made from fragile glass material, impulse and
pressure to the screen should be avoided
• Do not touch the display surface or stain it. As
the surface of the polarizer is very soft and
easily scratched, only use a soft dry cloth
without chemicals for cleaning
• Do not allow water or liquids to remain on the
surface for long. This may cause local
deformation or discoloration
• If the LCD breaks, and the liquid crystal runs
out, keep it well clear of your mouth and eyes.
If it sticks to your skin or clothes, wash it off
immediately with soap and water
• Do not touch or handle the PCB without first
touching the chassis (ground) due to ESD
(electro-static discharge)
• Remove all cable connections before inserting
new modules
• Do not operate in temperatures over 40°
Celsius, 120° Fahrenheit
