Using the LCD screen correctly
Handling the LCD screen
When the LCD screen is subjected to direct sunlight for a
long period of time, it will become very hot, resulting in pos-
sible damage to the LCD screen. When not using this prod-
uct, avoid exposing it to direct sunlight as much as possible.
The LCD screen should be used within the temperature
ranges shown in
Specifications
on page 65.
Do not use the LCD screen at temperatures higher or lower
than the operating temperature range, because the LCD
screen may not operate normally and could be damaged.
The LCD screen is exposed in order to increase its visibility
within the vehicle. Please do not press strongly on it as this
may damage it.
Do not push the LCD screen with excessive force as this may
scratch it.
Never touch the LCD screen with anything besides your
finger when operating the touch panel functions. The LCD
screen can scratch easily.
Liquid crystal display (LCD) screen
If the LCD screen is near the vent of an air conditioner, 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 this
product, resulting in possible damage.
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 malfunction.
The LCD screen will be difficult to see if it is exposed to direct
sunlight.
When using a cellular phone, keep the antenna of the cel-
lular phone away from the LCD screen to prevent disruption
of the video in the form of disturbances such as spots or
colored stripes.
Maintaining the LCD screen
When removing dust from or cleaning the LCD screen, first
turn this product off and then wipe the screen with a soft dry
cloth.
When wiping the LCD screen, take care not to scratch the
surface. Do not use harsh or abrasive chemical cleaners.
LED (light-emitting diode) backlight
A light emitting diode is used inside the display to illuminate the
LCD screen.
At low temperatures, using the LED backlight may increase
image lag and degrade the image quality because of the
characteristics of the LCD screen. Image quality will improve
with an increase in temperature.
The product lifetime of the LED backlight is more than
10 000 h
ours. However, it may decrease if used in high
temperatures.
If the LED backlight reaches the end of its product lifetime,
the screen will become dimmer and the image will no longer
be visible. In that case, please consult your dealer or the
nearest authorized Pioneer Service Station.
