The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. CAUTION Use of controls or adjustments or performance of proce- dures other

6、 than those specified herein may result in haz- ardous radiation exposure. 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. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser di

7、ode 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

8、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

9、checking the laser diode emission, observe from more than 30 cm away from the objective lens.

How to operate with a single unit Normally this set does not operate with a single unit. When you must be mending, connect to other unit. If the SYSTEM POWER switch of

13、the amplifire is set to ON, the power supply of the set is turned on. In case of other unit is nothing, the service box (PFJ-1) and exclusive jig (J-2501-078-A) are necessary to operate the set with a single unit. In case of above mentioned, press the p button and TIME button at the same time, to en
