DVD-C900 DVD-C900 1. Critical Components Information. Components having special characteristics are marked and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only). When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. Meter impedance should be equivalent to 1500 ohm shunted by 0.15µF. Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities. EQUIPMENT UNDER TEST WALL OUTLET INSULATING TABLE AC LEAKAGE TESTER OR EQUIVALENT < CAUTION:USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. THE COMPACT DISC PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIED SERVICE PERSONNEL. PROTECTION OF EYES FROM LASER BEAM DURING SERVICING TO SERVICE PERSONNEL 1 This set employs a laser. Therefore, be sure to carefully follow the instructions below when servicing . 1. Pickup Wave length : 655 nm Laser power : CLASS II2. When checking the laser diode emission, keep your eyes more than 30 cm away from the objective lens.
