NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential dif ference g enerated b y the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
The flexible board is easily damag ed and should be handled with
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, w hen c hecking the laser diode emission,
observe from more than 30 cm away from the objective lens.
Use of controls or adjustments or performance of procedures
other than those specif ied herein ma y result in hazardous
If the optical pic k-up block is defecti ve, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical pick-
