Techno Tidbits & Problem-solving
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.

Maintenance of External Surfaces
• 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.
