3.9 Attention when pick-up is exchanged
(1) Flexible wire, pick-up spring, switch actuator, and lead
spring are removed from an old pick-up (broken the one).
< Guide >
Flexible wire, pick-up spring and switch actuator,lead
spring are removed without each decomposing while
assembled.
(2) The above-mentioned parts are installed in a new pick-up
(non-defective article).
(3) A flexible wire is inserted in the connector which has taken
side with the pick-up, and solder is put up to short land part
"a" two places on a flexible wire.
(4) The electrostatic breakdown protection circuit attached to
the pick-up is cut.
< ATTENTION >
Please cut the electrostatic breakdown protection cir-
cuit attached to the pick-up after solder is put up to
two places on a flexible wire short land part "a" of the
insertion of a flexible wire this time in the connector
without fail.
The procedure might be mistaken and if solder has
not surely adhered to two places on a flexible wire
short land part "a", the laser diode in the pick-up be
destroyed again.
(5) The pick-up is installed in the traverse mechanism.
(6) A flexible wire is connected with connector CN101 on the
servo control board by installing the traverse mechanism
in the loading mechanism.
(7) Solder in two places on a flexible wire in part "a" is re-
moved.
< ATTENTION >
Please remove solder in two places in part "a" after
connecting a flexible wire with connector CN101 on
the servo control board without fail this time.
When the procedure is mistaken, the laser diode in the
pick-up might be destroyed.
Please remove solder in two places in part "a" surely.
