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.
S-102
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 inter-
nal 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.
◎ 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 ! 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.
◎ Inspect for safety after servicing!
Check that all screws, parts and wires removed or di sconnected 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, h eadphones
terminal, microphone terminal, input terminal, etc.) is 1MΩ or
greater. If it is less, the set must be inspected and repaired.
CAUTION
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 sigh t, 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 ! mark.
(2) Parts lists ... Indicated by the ! mark.
Concerning important safety parts
Using parts other than the designated parts
could result in electric shock, fires or other
dangerous situations.
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.

DIAGNOSTICS OF OPTICAL PICKUP
AND REPLACING TRAVERSE UNIT
Make failure diagnostics of the Optical Pickup as follows.
If the laser drive current (Iop) becomes more than 1.5 times of
the initial value, the Optical Pickup should be replaced.
The laser drive current initial value is checked by "Iop checked
Method" of next page.
In case of replacing the Pickup, change the whole part of the
Traverse Unit.
No mechanical adjustment is necessary after the replacement.
