Additional Information
Liquid crystal display (LCD) screen
! If the display is near the vent of an air con-
ditioner when it is opened, make sure that
air from the air conditioner is not blowing
on it. Heat from the heater may damage
the LCD screen, and cool air from the cool-
er 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 in-
side 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.
! When using a portable phone, keep the an-
tenna of the portable phone away from the
display to prevent disruption of the video by
the appearance of spots, colored stripes,
etc.

For viewing the LCD comfortably

Due to its construction, the viewing angle of
the screen size is limited. You can adjust it by
changing either screen size or picture adjust-
ment.
LED (light-emitting diode)
backlight
! 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.
! To protect the LED backlight, display will
darken in the following environment:
— In the direct sunlight
— Near the heater vent
! 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
dark and the image will no longer be pro-
jected. In this case, please consult your
dealer or the nearest authorized PIONEER
Service Station.
