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.
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.
Maintenance
Cleaning inside the deck
Clean the heads regularly to assure good quality playback and record-
ing. Use a cleaning tape (not included).
Care of the CD lens
Clean the lens regularly to prevent malfunctions.
Use a blower to remove dust and a cotton swab
if it is extremely dirty.
Recommended product:
Lens cleaner kit (part no. SZZP1038C).

described in these instructions or as marked on the unit.
2. Polarization—The unit is equipped with a polarized power plug where
one blade is wider than the other. This safety feature ensures that
the plug fits into your household AC outlet only one way. If the plug
doesn’t fit one way, try reversing it. If the plug still doesn’t fit, contact
an electrician to replace the obsolete outlet. Do not attempt to defeat
the safety purpose of the plug.
3. Power cord protection—Route the AC power supply cord so that it
will not be walked on or pinched by items placed on or against it.
Never take hold of the plug or cord with wet hands. Always grasp the
plug body firmly when connecting and disconnecting it.
4. Overloading—When connecting the AC power supply cord, be careful
not to overload the household AC outlet, extension cord, or outlet
from any other device as this can result in fire or electric shock.
