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.

En
VENTILATION
÷ When installing this unit, make sure to leave space around
the unit for ventilation to improve heat radiation (at least 60
cm at top, 10 cm at rear, and 30 cm at each side). If not
enough space is provided between the unit and walls or
other equipment, heat will build up inside, interfering with
performance or causing malfunctions.
÷ Do not place on a thick carpet, bed, sofa or fabric having a
thick pile. Do not cover with fabric or other covering.
Anything that blocks ventilation will cause internal temperature to rise, which may lead to breakdown or fire
hazard.
POWER-CORD CAUTION
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 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.

By interconnecting the CONTROL jacks of Pioneer units with
the Î mark, the entire system can be operated with this
remote control unit, although some of the units (AM/FM
tuner, CD player, cassette deck, etc.) may not be equipped
with remote sensors. The entire system can be operated by
a remote control unit by connecting PIONEER stereo components to each other using the control input (CONTROL IN) jack
on each component. Use the remote control cord supplied
with the respective unit for the connection. An example is
shown in the figure. As long as you connect “OUT” to “IN”,
the connecting sequence is arbitrary. When a unit has only an
“IN” connector, however, connect it last.
NOTE:
When the POWER switch is set to OFF, the components
connected to the CONTROL OUT jack can not be operated
with the remote control unit.
