Safety PfeGaUtiOnS (rhis"sarety

1. Eefore
servicing,
unplug
the
power
cord to
prevent
an
electric shock.
2. When
replacing
parts,
use only manufacturer's recommended
components for safety.
3.
Check the
condit¡on
of
the
power
cord. Replace
if wear
or damage is evident.
4. After
servicing,
be sure
to
restore
the lead
dress, insulation
barriers, insulation
papers,
shields, etc.
5. Before returning
the
servrced equipment
to the customer,
be sure to make the following
insulation
resistance
test
to
prevent
the
customer from
being exposed to
a shock hazard
.
Insulation
Resistance
Test
1. Unplug
the
power
cord and short
the two
prongs
of the
plug
with
a
jumper
wire.
2. f
urn on the
power
switch.
3. Measure
the resistance
value with
ohmmeter between
the
jumper
AC
plug
and each exposed metal
cabinet
part,
such
as screwheads,
antenna, control
shafts, handle
brackets, etc. Equipment with
antenna
term¡nals
should read
between
3MQ and 5.2MO to
all exposed
parts-.
(
Fig.
1
)
Equipment without
antenna
term¡nals
should read
approximately infinity
to all exposed
parts.
(
Fig. 2
)
.Note
:
Some
exposed
parts
may
be isolated from
the chassis
by design. These will read infinity.
4. lf the measurement
is outside the
specified limits,
there is
a
possibility
of a shock hazard. The
equipment
should
be repaired
and rechecked
before it is returned
to the
customer.

lf this occurs, follow the
procedure
outlines below:
1. Turn off the
power.
2. Determine the
cause of the oroblem and correct it.
3. Turn on the
power
once again after one
m¡nute.
Note:
When the
protection
circuitry
functions,
the unit will not operate unless
the
power
is first turned off
and
then
on again.
I
Protection
Circuitry
The
protection
circuitry may have
operated ¡f
either of the follow¡ng
conditions
are noticed:
.
No
sound is heard
when the
power
is turned
on.
.
Sound
stops during
a
performance.
The f
unction
of this circuitry
is to
prevent
c¡rcuttry
damage if
,
for
example,
the
positive
and negative
speaker
connection wires
are
"shorted',,
or
if
speaker
systems with
an impedance
less than
the indicated rated
impedance
of the
amplifier
are used.
I Precaution
of
Laser
Diode
CAUTION:
This
unit utrlizes
a class 1 laser. Invisrble
laser radiation
is emitted from
the optical
pick
up lens.
When
the unit is
turned on :
1. Do
not look
directly into the
pick
up lens.
2. Do not
use
optical insturments
to look
at the
pick
up lens.
3.
Do
not adjust
the
preset
variable
resistor
on the
pick
up
lens.
4. Do not
disassemble
the
optical
pick
up
unit.
5. lf the
optical
pick
up is replaced,
use the manufacturer's
specified replacement
pick
up only.
6. Use of
control or
adjustments or
performance
of
procedures
other than those
specified
herein
may
result
in hazardous radiation
exoosure.
CAUTION!

PRODUCT
UTILIZES
A LASER.
USE
OF CONTROLS
OR ADJUSTMENTS
OR PERFORMANCE
OF PROCEDURES
OTHER THAN THOSE
SPECIFIED
HEREIN
MAY
RESULT
IN HAZARDOUS
