Pull out disc table NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical

10、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 rep

11、air 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

12、diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output two times. CD-TEXT TEST DISC This unit is able to display the text data (char

13、acter information) written in the CD on its fluorescent indicator tube. The CD-TEXT TEST DISC (TGCS-313: J-2501-126-A) is used for checking the display. To check, perform the following procedure. Procedure: 1. Turn ON the power and set the test disc. 2. Press the ” button and play back the disc. 3.

14、The following will be displayed on the fluorescent indicator tube. Display : 1kHz/0 dB/ L&R 4. Rotate the AMS knob to switch the track. The text data of each track will be displayed. Restrictions in CD-TEXT Contents and Display The micro processors RAM has limit of capacity in this unit, The display

15、 may not show all the track titles in a disc when you play the CD TEXT TEST DISC, but it is not unusual. In that case, “NOT DISPLAY” appears in the display.
