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 moist-
ure to form inside the navigation unit, re-
sulting 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 mobile phone, keep the aer-
ial of the mobile phone away from the LCD
screen to prevent disruption of the video in
the form of disturbances such as spots or
coloured stripes.

Maintaining the LCD screen

! When removing dust from the LCD screen
or cleaning it, first turn the system power
off, then wipe 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 dis-
play to illuminate the LCD screen.
! At low temperatures, using the LED back-
light may increase image lag and degrade
the image quality because of the character-
istics 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 authorised Pioneer
Service Station.
