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,
observe from more than 30 cm away from the objective lens.
Notes on Chip Component Replacement
Never reuse a disconnected chip component.
Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
This label is located on the bottom of the chassis.
This label is located on the drive unit’s internal chassis.
optical pick-up block
semi-fixed resistor
SERVICE NOTES
If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical
pick-up block.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
TEST DISCS
This set can playback CD-R and CD-ROM discs. The following
test discs should be used to check the capability:
CD-R test disc TCD-R082LMT (Part No. J-2501-063-1)
CD-RW test disc TCD-W082L (Part No. J-2501-063-2)
NOTES ON CD-R/CD-RW DISCS
You can play CD-Rs (recordable CDs)/CD-RWs (rewritable CDs)
designed for audio use on this unit.
Look for these marks to distinguish CD-Rs/CD-RWs for audio
use.
These marks denote that a disc is not for audio use.
Some CD-Rs/CD-RWs (depending on the equipment used for its
recording or the condition of the disc) may not play on this unit.
You cannot play a CD-R/CD-RW that is not finalized
.
A process necessary for a recorded CD-R/CD-RW disc to be
played on the audio CD player.
