● 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 dr y
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 hours. 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.
