Precautions for handling the pickup and
semiconductors (particularly the ICS)
The pickup and semiconductors (particularly the ICS) may
be damaged if they come into contact with a source of
high voltage static electricity. Do not bring them,
therefore, into contact with or into the vicinity of anything
which has been charged with high voltage static.
The pickup consists of a large number of optical and
precision parts. Do not store or repair it, therefore, in any
location with a high temperature, high humidity, high
magnetic fields or high dust concentration. (Since the
pickup contains a powerful magnet, it must not be brought
near any magnetized objects.)
Do not apply strong external pressure to the pickup or
subject it to impact. Actions like these can cause the
printed circuit board to crack or malfunctioning to occur.
The pickup is a single integrated part which has been
very precisely adjusted. Therefore, its adjustment points
and set screws must not be touched.
How to prevent static during handling
When replacing any of the parts, disconnect the power
plug from the unit being repaired.
All measuring instruments, tools and repair equipment
must be grounded. Cover the work bench where the
repair work will be done with a grounded electrically
conductive sheet.
Ground the metal part of the soldering iron in order to
safeguard against leakage of electricity from the heater.
,,,r
d
[F,]
Repair personnel must wear grounding bands around their
wrists to discharge static picked up by their bodies. These
bands are grounded through a resistor (with a 1Mf2
resistance).
Note: Under no circumstances must be the grounding bands
e.
3.
a.
b.
be grounded without a resistor (with a 1ML? resistance)
since doing so involves the risk of electric shocks.
Since static in the clothes of the repair personnel will not
be discharged by wearing grounding bands, every care
must be taken not to allow the clothes to touch the pickup
and semiconductors (particularly the ICS). >’” “The pickup, which is a single integrated part, is kept in a
conductive bag. Use this bag to convey the pickup from
one place to another. In order to avoid damage resulting
from static which may occur when the pickup is removed
from the bag, make sure that it is not placed on top of the
bag.
Cleaning the lens surface
Blow off dust on the lens using the kind of air brush which
is used for cameras.
Remove stubborn dirt with a cotton swab dipped in
isopropyl alcohol. Do not use any other type of cleaning
fluid since it may mark the plastic lens.
Notes: ●Do not use too much isopropyl alcohol: the excess
may seep inside the pickup.●The lens is held in place by a very feeble support
spring. Therefore, when cleaning the lens, avoid
applying any more force by the cotton swab than is
necessary since this may bend the support spring --._-

PARTS LIST
PRODUCT SAFETY NOTICEEach precaution in this manual should be followed during servicing. Components identified with the IEC symbol ~ in the parts listand the schematic diagram designate components in which safety can be of special significance. When replacing a component identi-fied ~, use only the replacement parts designated, or parts with the same ratings of resistance, wattage or voltage that are desig-nated in the parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed partsare acceptably insulated from the supply circuit before returning the product to the customer.
CAUTION: Regular type resistors and capacitors are not list. To know those values, refer to the schematic diagram.
