SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.
LASER RADIATION
Do not stare into beam or view directly with optical instruments, class 3A laser product.
CAUTION
Please heed the points listed below during servicing and inspection.
◎ Heed the cautions!
Spots requiring particular attention when servicing, such
as the cabinet, parts, chassis, etc., have cautions indicated
on labels or seals. Be sure to heed these cautions and the
cautions indicated in the handling instructions.
◎ Caution concerning electric shock!
(1) An AC voltage is impressed on this set, so touching in-
ternal metal parts when the set is energized could
cause electric shock. Take care to avoid electric shock,
by for example using an isolating transformer and
gloves when servicing while the set is energized, unplugging the power cord when replacing parts, etc.
(2)There are high voltage parts inside. Handle with extra
care when the set is energized.
◎ Caution concerning disassembly and
assembly!
Though great care is taken when manufacturing parts from
sheet metal, there may in some rare cases be burrs on the
edges of parts which could cause injury if fingers are
moved across them. Use gloves to protect your hands.
◎ Inspect for safety after servicing!
Check that all screws, parts and wires removed or disconnected for servicing have been put back in their original positions, inspect that no parts around the area that has been
serviced have been negatively affected, conduct an insulation check on the external metal connectors and between
the blades of the power plug, and otherwise check that
safety is ensured.
(Insulation check procedure)
Unplug the power cord from the power outlet, disconnect
the antenna, plugs, etc., and turn the power switch on. Using a 500V insulation resistance tester, check that the insulation resistance between the terminals of the power
plug and the externally exposed metal parts (antenna terminal, headphones terminal, microphone terminal, input
terminal, etc.) is 1MΩ or greater. If it is less, the set must
be inspected and repaired.
CAUTION
Concerning important safety
parts
◎ Only use designated parts!
The set's parts have specific safety properties (fire resistance, voltage resistance, etc.). For replacement parts, be
sure to use parts which have the same properties. In particular, for the important safety parts that are marked z on
wiring diagrams and parts lists, be sure to use the designated parts.
◎ Be sure to mount parts and arrange
the wires as they were originally!
For safety reasons, some parts use tape, tubes or other insulating materials, and some parts are mounted away from
the surface of printed circuit boards. Care is also taken with
the positions of the wires inside and clamps are used to
keep wires away from heating and high voltage parts, so
be sure to set everything back as it was originally.
Many of the electric and structural parts used in the set
have special safety properties. In most cases these properties are difficult to distinguish by sight, and using replacement parts with higher ratings (rated power and
withstand voltage) does not necessarily guarantee that
safety performance will be preserved. Parts with safety
properties are indicated as shown below on the wiring diagrams and parts lists is this service manual. Be sure to replace them with parts with the designated part number.
(1) Schematic diagrams ... Indicated by the z mark.
(2) Parts lists ... Indicated by the z mark.
Using parts other than the designated
parts could result in electric shock, fires or
other dangerous situations.

WIRE ARRANGEMENT
If wire bundles are untied or moved to perform adjustment or parts replacement etc.,be sure to rearrange them neatly as
they were originally bundled or placed afterward.
Otherwise, incorrect arrangement can be a cause of noise generation.

Note Handling and Replacement of the Laser pick-up
1. Protection of the LD
Short a part of the LD circuit by soldering. After connection to a circuit, remove the short solder.
2. Precautions when handling the laser CD mechanism
• Handle the laser pick-up so that it is not exposed to dust.
• Do not leave the laser pick-up bare. Be sure to cover it.
• If dust adheres on lens of the pick-up, blow it off with a blower brush.
• Do not shock the laser pick-up.
• Do not watch the light of the laser pick-up.
3. Cautions on assembling and adjustment
• Be sure that to the bench, jig, head of soldering iron (with ceramic) and measuring instruments are well grounded.
• Workers who handle the laser pick-up must be grounded.
• The finished mechanism (prior to anchoring in the set) should be protected against static electricity and dust. The mechanism must be stored that damaging outside forces are not received.
• When carrying the finished mechanism, hold it by the
chassis body
• For proper operation, storage and operating environment should not contain corrosive gases. For example H
CI
2 etc. In addition storage environment should not have materials that emit corrosive gases especially from silicic, cyanic,
formalin and phenol group. I the mechanism or the set, existence of corrosive gases may cause no rotation in motor.
2S, SO2, NO2,
4. Determining whether the laser pick-up is defective
•
Measure the waveform at RFO-VC on "MCU P.W.B. Unit ".
( For measuring points and waveforms, see pages 21.)
• The laser pick-up is OK if the amplitude level of the measured RFO waveform is between 0.4 and 1.1 Vp-p, defective otherwise.
Protective soldering place for laser diode.
