Precautions
Before using this unit please read these operating instructions care¬
fully. Take special care to follow the warnings indicated on the unit
itself as well as the safety suggestions listed below.
Afterwards keep them handy for future reference.
Safety _
1. Power Source —The unit should be connected to power supply
only of the type described in the operating instructions or as
marked on the unit.
2. Polarization —If the unit is equipped with a polarized AC power
plug {a plug having one blade wider than the other), that plug will
fit into the AC outlet only one way. This is a safety feature. If you
are unable to insert the plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit, contact your electrician to
replace your obsolete outlet. Do not defeat the safety purpose of
the polarized plug.
3. Power Cord Protection —AC power supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against them. Never take hold of the plug or
cord if your hand is wet, and always grasp the plug body when
connecting or disconnecting it.
4. Nonuse Periods —When the unit is not used, turn the power off.
When left unused for a long period of time, the unit should be
unplugged from the household AC outlet.

Listening caution
Selecting fine audio equipment such as the unit you’ve just pur¬
chased 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 In¬
dustries 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 an¬
noying blaring or distortion—and, most importantly, without affec¬
ting your sensitive hearing.
We recommend you to avoid prolonged exposure to excessive
noise.
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.
