FM/AM COMPACT DISC PLAYER 9-889-023-01 2008C04-1 © 2008.03 Sony Corporation Audio Business Group Published by Sony Techno Create Corporation CDX-GT373A NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down 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 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 damaged by heat. TEST DISCS Please use the following test discs for the check on the CD section. YDES-18 (Part No. 3-702-101-01) PATD-012 (Part No. 4-225-203-0.
