The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. The following caution label is located inside the unit. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. HCD-EP305 SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. 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. Flexible Circuit Board Repairing • Keep the temperature of soldering iron around 270˚C during repairing. • Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). • Be careful not to apply force on the conductor when soldering or unsoldering.

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 pick- up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK 1. Press the ?/1 button to the power ON with no disc inserted and press the CD button. 2. Open the lid for CD. 3. Turn on SW600 as following figure. 4. Confirm the laser diode emission while observing the objecting lens. When there is no emission, Auto Power Control circuit or Optical Pick-up is broken. Objective lens moves up and down five times for the focus search. SW600 CASSETTE board MAIN board HEADPHONE board at least 30 mm heatsink TO PREVENT ‘TAPE OSCILLATION SOUND AT VOLUME’ MAXIMUM SETTING (W/O TAPE) Headphone wire dressing: a.) Draw the wire from Main board to Headphone board along the bottom side of heatsink. b.)
