About the Liquid Crystal Display (LCD) Screen
• If the display is near the vent of an air conditioner when it is deployed, make sure
that air from the air conditioner is not blowing on it. Heat from the heater may
break the LCD screen, and cool air from the cooler may cause moisture to form
inside the display resulting in possible damage. Also, if the display is cooled down
by the cooler, the screen may become dark, or the life span of the small fluorescent
tube used inside the display may be shortened.
• Small black dots or white dots (bright dots) may appear on the LCD screen. These
are due to the characteristics of the LCD screen and do not indicate a problem with
the display.
• At low temperatures, the LCD screen may be dark for a while after the power is
turned ON.
• The LCD screen will be difficult to see if it is exposed to direct sunlight.
Keeping the Display in Good Condition
• When removing dust from the screen or cleaning the display, first turn the system
power OFF, then wipe with a soft dry cloth.
• When wiping the screen, take care not to scratch the surface. Do not use harsh or
abrasive chemical cleaners.
About the Small Fluorescent Tube
• A small fluorescent tube is used inside the display to illuminate the LCD screen.
* The fluorescent tube should last for approximately 10,000 hours, depending on
operating conditions. (Using the display at low temperatures reduces the service
life of the fluorescent tube.)
* When the fluorescent tube reaches the end of its useful life, the screen will be
dark and the image will no longer be projected. If this happens, consult your
dealer or the nearest authorized PIONEER Service Station.
