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 difference generated by 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
parts.
The flexible board is easily damaged and should be handled with
care.
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, when checking the laser diode emission, ob-
serve more than 30 cm away from the  objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Close the tray for CD.
2. Press CD u button.
3. Confirm the laser diode emission while observing the objecting
lens. When there is no emission, Auto Power Control circuit or
Optical Pick-up is broken.
Objective lens moves up and down once for the focus search.
CAUTION DURING WHEN MOUNTING THE PULLEY
FOR THE LOADING MOTOR
Make the following adjustment when mounting the loading motor
(part number : 1-698-999-11) and motor pulley (part number : 2-
627-174-01) of the CD section.
Specification :   A = 0.9 to 1.1mm
