4、CN 收音机爱 好者资料库 The following items should be checked for continued protection of the customer and the service technician. Leakage current check Before returning the set to the customer, be sure to carry out either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage c

5、urrent exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the set is defective. Be sure to test for leakage current with the AC plug in both polarities, in addition, when the sets power is in each state (on, off and standby mode), if app

6、licable. CAUTION Please heed the following cautions and instructions during servic- ing and inspection. Heed the cautions! Cautions which are delicate in particular for servicing are labeled on the cabinets, the parts and the chassis, etc. Be sure to heed these cautions and the cautions described in

7、 the handling instructions. Cautions concerning electric shock! (1) An AC voltage is impressed on this set, so if you touch internal metal parts when the set is energized, you may get an electric shock. Avoid getting an electric shock, by using an isolating transformer and wearing gloves when servic

8、ing while the set is energized, or by unplugging the power cord when replacing parts, for example. (2) There are high voltage parts inside. Handle with extra care when the set is energized. Caution concerning disassembly and assembly! Through great care is taken when parts were manufactured from she

9、et metal, there may be burrs on the edges of parts. The burrs could cause injury if fingers are moved across them in some rare cases. Wear gloves to protect your hands. Use only designated parts! The sets parts have specific safety properties (fire resistance, voltage resistance, etc.). Be sure to u

10、se parts which have the same properties for replacement. The burrs have the same properties. In particular, for the important safety parts that are indicated by the z mark on schematic diagrams and parts lists, be sure to use the designated parts. Be sure to mount parts and arrange the wires as they

11、 were originally placed! For safety seasons, some parts use tapes, tubes or other insulating materials, and some parts are mount- ed away from the surface of printed circuit boards. Care is also taken with the positions of the wires by arranging them and using clamps to keep them away from heating a

12、nd high voltage parts, so be sure to set everything back as it was originally placed. Make a safety check after servicing! Check that all screws, parts and wires removed or disconnected when servicing have been put back in their original positions, check that no serviced parts have deteriorate the a

13、rea around. Then make an insulation check on the external metal connectors and between the blades of the power plug, and otherwise check that safety is ensured. (Insulation check procedure) Unplug the power cord from the power outlet, disconnect the antenna, plugs, etc., and on the power. Using a 50

14、0V insulation resistance tester, check that the insulation resistance value between the inplug and the externally exposed metal parts (antenna terminal, headphones terminal, input terminal, etc.) is 1M or greater. If it is less, the set must be inspected and repaired. Many of the electric and the st

15、ructural parts used in the set have special safety properties. In most cases these properties are difficult to distinguish by sight, and the use of replacement parts with higher rat- ings (rated power and withstand voltage) does not necessarily guarantee that safety performance will be preserved. Pa

16、rts with safety properties are indicated as shown below on the wiring diagrams and the parts list in this service manual. Be sure to replace them with the parts which have the designated part number. (1) Schematic diagrams Indicated by the z mark. (2) Parts lists Indicated by the z mark. The use of

17、parts other than the designated parts could cause electric shocks, fires or other dangerous situations.

If the leakage current exceeds 0.5 milliamps, or if the resis

22、replacement parts recommended by the manufacturer. Electrostatic breakdown of the semi-conductors or optical pickup may occur due to a potential differ- ence caused by electrostatic charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a grounding band (1 M ohm) that is pr

Ground for Workbench Be sure to place a conductive sheet or copper plate with proper grounding (1 M ohm) on the work- bench or other surface, where the semi-conductors are to be placed.
