WARNING:
Parts indicated by the
z
mark have critical characteristics. Use ONLY replacement parts recommended
by the manufacturer.
CAUTION:
Before returning the set to the customer, be sure to carry out 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 set is defective.
WARNING:
DO NOT return the set to the customer unless the problem is identified and remedied.
NOTICE:
ALL RESISTANCE VALUES IN OHM. k=1,000 OHM / M=1,000,000 OHM
ALL CAPACITANCE VALUES ARE EXPRESSED IN MICRO FARAD, UNLESS OTHERWISE INDICATED. P
INDICATES MICRO-MICRO FARAD. N INDICATES NANO FARAD. EACH VOLTAGE AND CURRENT ARE
MEASURED AT NO SIGNAL INPUT CONDITION. CIRCUIT AND PARTS ARE SUBJECT TO CHANGE WITHOUT
PRIOR NOTICE.
1. Parts indicated by "
nsp
" on this table cannot be supplied.
2. When ordering a part, make a clear distinction between "1" and "I" (i) to avoid mis-supplying.
3. A part ordered without specifying its part number can not be supplied.
4. Part indicated by "
@
" mark is not illustrated in the exploded view.
WARNING: Parts indicated by the
z
mark have critical characteristics. Use ONLY replacement parts
recommended by the manufacturer.
Electrostatic breakdown of the semi-conductors or optical pickup may occur due to a potential differ-
ence caused by electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1 M ohm) that is properly grounded to remove any static electricity
that may be charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with proper grounding (1 M ohm) on the work-
bench or other surface, where the semi-conductors are to be placed. Because the static electricity
charge on clothing will not escape through the body grounding band, be careful to avoid contacting
semi-conductors with your clothing
