7、 protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, meta
8、l over- lays, control shaft, etc.). Plug the AC line cord of the appli- ance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTEN- TIAL SHOCK HAZARD AND MUST BE
9、 CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUS- TOMER. Device under test Test all exposed metal surfaces Also test with plug reversed (Using AC adapter plug as required) AC Leakage Test Leakage current tester Reading should not be above 0.5mA Earth ground RadioFans.CN 收音机爱 好者资料库 - 4 - LASER BE
10、AM SAFETY PRECAUTIONS CLASS 1 LASER PRODUCT DANGER INVISIBLE LASER RADIATION AVOID DIRECT EXPOSURE TO BEAM This Receiver 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 1 foot aw
11、ay from the pickup lens when the diode is turned on. 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. Do not look directly at the laser beam coming from the pickup or a
12、llow it to strike against your skin. Laser Beam Radiation - 5 - HANDLING LASER PICKUP The laser diode in the optical system of this receiver can be damaged by electrostatic discharge from clothes, body, etc. Proper electrostatic grounding for service personnel is required during servicing. BEFORE RE
13、PAIRING THE DVD MECHANISM a. Human Body Grounding: Many of the components used in this compact disc player, including the laser pickup, are sensitive to electrostatic dis- charge. Service personnel should be grounded with an electrostatic armband (1M ohm). Caution: Static charge on clothing does not
14、 escape through a body grounding wristband. Be careful not to contact the pickup or electrical components with your clothing. b. Workbench and Tool Grounding: A properly-grounded electroconductive plate (1 M ohm) or metal sheet should be fitted to the workbench surface. Tools and instruments (solder
15、ing irons, scopes, etc.) should be grounded to prevent AC leakage. c. Make two standard ESD solder bridges on the Laser optic PC Board Before disassembly of mechanism or disconnect any cables in it, make two standard ESD solder bridges on the laser optic PC Board.
