SERVICE NOTES

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.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

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.

optical pick-up bloc

semi-fixed resistor

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 pickup 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.

• CDX-CA700/CA700X: AEP, UK model

This label is located on the bottom of the chassis.

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 (re writable 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.

This label is located on the drive unit’s internal chassis.
