SAFETY INFORMATION
This product has been designed and manufactured according to FDA
regulations "title 21, CFR, chapter 1, subchapter J, based on the Radiation
Control for Health and Safety Act of 1968", and is classified as a class 1
laser product. There is no hazardous invisible laser radiation during
operation because invisible laser radiation emitted inside of this product
is completely confined in the protective housings.
The label required in this regulation is shown 1.
OCAUTION
USE OF CONTROLS OR ADJUSTMENT OR PERFORMANCE OF
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.
Optical pickup:
Type : KSS-151A
Manufacturer : SONY Corporation
Laser output : Less than 0.2 mW on the objective lens
Wavelength : 760 - 800 nm
1For U.S.A.
2-1-2 Objective
●Never look directly into the LD or observe the laser beam
through another lens or mirror.
●Don't touch the objective with fingers.
●If objective becomes dirty, playback will deteriorate.
To clean the objective, moisten a good cleaning tissue, such as
made by KODAK, in isopropyl alcohol and wipe the objective
gently. Wipe off and excess fluid with a dry cleaning tissue.
2-2 Sled balance adjustment
1. Adjust V403 for 0V potential between P415 pin 1 (SO) and pin
2 (GND).
2-1 Replacement of the Pickup Assembly
2-1-1 Cautions in handling
●Before removing the pickup assembly be sure to solder-bridge
where indicated in the inset to prevent the laser diode from
being electrostatically damaged. After replacing the pickup
assembly, be sure to unsolder the antistatic bridge. Or else the
laser diode does not function.
●Before servicing the pickup assembly be sure to prevent
electrostatic-inducer destruction by grounding not only test
equipment in use but also yourself.
●In case of mounting and dismounting the assembly, do not
touch the actuator, photosensor and LD plate.
●Don't touch the plated portion of the flat cable end directly with
fingers.
●Use care not to break the flat cable.
●Soldering must be done quickly at less than 30W, 320℃.
●Don't disassemble the pickup ass'y.
●Don't apply shock to the pickup ass'y.
●Don't place the assembly in a place subject to excessive dust,
heat or moisture.
2 ADJUSTMENTS AND CHECKS
−3−
The pickup is secured with an anti-vibration clamp in order to
reduce vibration during transport. This must be released
before use.
Releasing the anti-vibration clamp
1. Place the unit on its side, left side down, as shown here.
2. Use the supplied tool and insert it into the hole on the bottom.
3. Turn the tool about 30 degrees counter-clockwise in the
FREE direction.
Securing the anti-vibration clamp
1. Remove any disc from the unit, disconnect the power, and
place the unit on its side, left side down, as shown here.
2. Use the supplied tool and insert it into the hole on the bottom.
3. Turn the tool about 30 degrees clockwise in the LOCK
direction.
NOTE:
You do not need to use force
to clamp and unclamp the
unit. This may damage the
unit. Use only the supplied
tool and turn gently.
