Pioneer VSX-D909S 用户手册

Selecting fine audio equipment such as the unit you’ve

just purchased is only the start of your musical enjoyment.
Now it’s time to consider how you can maximize the fun
and excitement your equipment  offers. This manufacturer
and the Electronic Industries Association’s Consumer
Electronics Group want you to get the most out of your
equipment by playing it at a safe level. One that lets the
sound come through loud and clear without annoying
blaring or distortion-and, most importantly, without
affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing

“comfort level” adapts to higher volumes of sound. So
what sounds  “normal” can actually be loud and harmful
to your hearing. Guard against this by setting your
equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it

comfortably and clearly, and without distortion.

Once you have established a comfortable sound level:
• Set the dial and leave it there.

Taking a minute to do this now will help to prevent

hearing damage or loss in the future. After all, we want
you listening for a lifetime.

Used wisely, your new sound equipment will provide a

lifetime of    fun and enjoyment. Since hearing damage from
loud noise is often undetectable until it is too late, this
manufacturer and the Electronic Industries Association’s
Consumer Electronics Group recommend you avoid
prolonged exposure to excessive noise. This list of sound
levels is included for your protection.

• Use a polishing cloth or dry cloth to wipe off dust

and dirt.

• When the surfaces are dirty, wipe with a soft

cloth dipped in some neutral cleanser diluted five
or six times with water, and wrung out well, and
then wipe again with a dry cloth. Do not use
furniture wax or cleaners.

• Never use thinners, benzine, insecticide  sprays

or other chemicals on or near this unit, since
these will corrode the surfaces.

Handle the power cord by the plug. Do not pull out
the plug by tugging the cord and never touch the
power cord when your hands are wet as this could
cause a short circuit or electric shock. Do not place
the unit, a piece of furniture, etc., on the power cord,
or pinch the cord. Never make a knot in the cord or tie
it with other cords. The power cords should be routed
such that they are not likely to be stepped on. A
damaged power cord can cause a fire or give you an
electrical shock. Check the power cord once in a
while. When you find it damaged, ask your nearest
PIONEER authorized service center or your dealer for
a replacement.
