SAFETY
INSTRUCTIONS
PRECAUTIONS DURING SERVICING
1.
Parts identified
by
the & ( * ) symbol parts are
critical for safety. Replace them only with parts
whose
numbers are specified.
2.
In addition to safety, other parts and assemblies are
specified for conformance with such regulations as
those applying to spurious radiation.
These must also
be
replaced only with specified
replacements.
.
Examples:
RF
converters, tuner units,
antenna
selection
switches,
RF
cables, noise-blocking capacitors,
noise-blocking filters. etc.
3.
Use specified internal Wiring. Note especially:
1)
Wires covered with
PVC
tubing
2) Double insulated wires
3) High voltage leads
4. Use specified insulating materials for hazardous live
parts. Note especially:
1)
Insulating Tape
2) PVC tubing
3) Spacers (insulating barriers)
4) Insulating sheets for transistors
5) Plastic screws for fixing micro switches
5.
When
replacing
AC
primary side components
(transformers, power cords, noise blocking capacitor,
etc.), wrap ends
of
wires securely about the terminals
before soldering.
c::)
C)
6.
Make sure that wires do not contact heat generating
parts (heat sinks, oxide metal film resistors, fusible
resistors, etc.)
7.
Check
if
replaced wires
do
not contact sharply edged
or
pointed parts.
8.
Also check areas surrounding repaired parts.
9.
Make
sure
that foreign objects (screws, solder droplets,
etc.)
do
not remain inside the set.
MAKE YOUR CONTRIBUTION TO PROTECT THE
ENVIRONMENT
Used batteries with the
ISO
symbol for
recycling
as
well as small accumulators
(rechargeable batteries), mini-batteries
(cells) and starter batteries should not
be thrown into the garbage can.
Please leave them at
an
appropriate depot.
SAFETY CHECK AFTER SERVICING
After servicing, make measurements of leakage-current
or resistance
in
order to check
if
exposed parts
are
acceptably insulated from the supply circuit.
The leakage-current measurement should be done
between accessible metal parts, (such as chassis,
ground terminal, microphone jacks, signal input/output
connectors, etc.) and the earth ground through a resister
of
1500 ohm paralleled with a 0.15 µ F capacitor, under
the unit's normal working condition.
The leakage-current should
be
less the
0.SmA
rms
AC.
The resistance measurement should be done between
accessible exposed metal parts and power cord plug
prongs with the power switch
"ON" (if included). The
2
resistance should be more than 2.2Mohms.
PRECAUTIONS IN REPAIRING
When repairing or adjusting the unit, please note the
following points
1 . Do not put excessive pressure on the mechanical"
part (operation part). including the pick-up block, as
extremely high mechanical precision is required
in
these parts.
2.
When the base is removed for repair
or
adjustment.
Make sure that there are no metal objects between
the
P.C
board or the mecha parts and the base.
3.
The Micro-Computer and the CD signal processing
ICs may
be
damaged by static electricity or leakage
from a soldering iron during repairing. While soldering,
please take the precautions against leakage as in
the illustration.
GND
4. Do not loosen any screws
in
the pick-up block.
Please refer to NOTE when replacing the pick
up
block.
5.
To avoid hazardous invisible Laser Radiation, do not
look at the Laser Beam (Objective lens) directly.
6.
On model for some countries. laser warning labels
are affixed
on
and inside of the unit as shown below.
For your safety, read these labels carefully before
repairing or adjusting the unit.
CAUTION
The use of controls or adjustments or the performance
of
procedures other than those specified herein may
result
in
hazardous radiation.
