Cautions on Handing
Liquid crystal screen
• There may be small black dots or brightly shining
spots (bright points) on the liquid crystal screen. This
is a particularity of liquid crystal screens, and is not a
malfunction.
• When using in cold places, the screen may be dark
for a while after the power is turned on. The
brightness will return to normal after a while.
• If the liquid crystal display is exposed to direct
sunlight, the sunlight will reflect off of it, making the
display hard to see. Block the direct sunlight.
Liquid crystal backlight
• The backlight will reach the end of its service life after
approximately 10 000 hours. (The service life may be
shortened if used continuously at high temperatures
on a rack or when used continuously in low
temperatures. When using on a rack, be sure to allow
for heat dissipation.)
Cleaning the shiny surfaces of the panel and

this receiver's surface.

water, wash the cloth by rubbing it against itself in
this solution, rinse it carefully to remove any traces of

• If the wiping cloth has been lost or is extremely dirty,
order a new one either from your nearest sales outlet
or directly from the Pioneer Parts Order Center. You
can also use a commercially available lens cleaning
cloth instead.
