Safety
Precautions
The

of
this
product
contains

for
safety
purposes.
For
continued
protection,
no
changes
should
be
made
to
the

unless
authorized
in
writing
by
the

identical
to
those
used
in
the
original
circuits.
Services
should
be
performed
by

for
personal
injury
or
property
damage
resulting
therefrom.
.Many
electrical
and
mechanical
parts
in

nor
can
the
protection
afforded
by
them
necessarily
be
obtained
by
using
replacement
components
rated
for

failed or defeated. Avoid direct exposure to beam.
3. CAUTION: Do not open the rear cover. There are no user
serviceable parts inside the unit; leave all servicing to
qualified service personnel.
4. CAUTION: The compact disc player uses invisible laser
radiation and is equipped with safety switches which
prevent emission of radiation when the disc holder is open
and the safety interlocks have failed or are defeated. It is
dangerous to defeat the safety switches.
5. CAUTION: Use of controls of adjustments or performance
of procedures other than those specified herein may result
in hazardous radiation exposure.
