9、 selfpollution curve Laser Beam Safety Precautions This Blu-Ray player uses a pickup that emits a laser beam. The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 30 cm away from the pickup lens when the diode is turned on

10、. Do not look directly at the laser beam. CAUTION: Use of controls and adjustments, or doing procedures other than those specified herein, may result in hazardous radiation exposure. Location: Inside Top of Blu-Ray mechanism. Do not look directly at the laser beam coming from the pickup or allow it

11、to strike against your skin.

Important Safety Precautions 3-2 4-1 Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterio

25、ration. Observe that screws, parts, and wires have been returned to their original positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards. 1. Clearance Distance When replacing primary circuit components, confirm specified clearance d

26、istance (d) and (d) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1) Table 1: Ratings for selected area Note:This table is unofficial and for reference only. Be sure to confirm the precise values. 2. Leakage Current Test Confirm the specified (or lower)

27、leakage current between B (earth ground, power cord plug prongs) and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) is lower than or equal to the specified value in the table below. Measuring M

28、ethod (Power ON): Insert load Z between B (earth ground, power cord plug prongs) and exposed accessible parts. Use an AC voltmeter to measure across the terminals of load Z. See Fig. 2 and the following table. Table 2: Leakage current ratings for selected areas Note:This table is unofficial and for
