3、 below during servicing and inspection.Heed the cautions!Spots requiring particular attention when servicing, suchas the cabinet, parts, chassis, etc., have cautions indicatedon labels or seals. Be sure to heed these cautions and thecautions indicated in the handling instructions.Caution concerning

4、electric shock!(1) An AC voltage is impressed on this set, so touching in-ternal metal parts when the set is energized couldcause electric shock. Take care to avoid electric shock,by for example using an isolating transformer andgloves when servicing while the set is energized, un-plugging the power

5、 cord when replacing parts, etc.(2)There are high voltage parts inside. Handle with extracare when the set is energized.Caution concerning disassembly andassembly!Though great care is taken when manufacturing parts fromsheet metal, there may in some rare cases be burrs on theedges of parts which cou

6、ld cause injury if fingers aremoved across them. Use gloves to protect your hands.Only use designated parts!The sets parts have specific safety properties (fire resis-tance, voltage resistance, etc.). For replacement parts, besure to use parts which have the same properties. In par-ticular, for the

7、important safety parts that are marked z onwiring diagrams and parts lists, be sure to use the desig-nated parts.Be sure to mount parts and arrangethe wires as they were originally!For safety reasons, some parts use tape, tubes or other in-sulating materials, and some parts are mounted away fromthe

8、surface of printed circuit boards. Care is also taken withthe positions of the wires inside and clamps are used tokeep wires away from heating and high voltage parts, sobe sure to set everything back as it was originally.Inspect for safety after servicing!Check that all screws, parts and wires remov

9、ed or discon-nected for servicing have been put back in their original po-sitions, inspect that no parts around the area that has beenserviced have been negatively affected, conduct an insu-lation check on the external metal connectors and betweenthe blades of the power plug, and otherwise check tha

10、tsafety is ensured.(Insulation check procedure)Unplug the power cord from the power outlet, disconnectthe antenna, plugs, etc., and turn the power switch on. Us-ing a 500V insulation resistance tester, check that the in-sulation resistance between the terminals of the powerplug and the externally ex

11、posed metal parts (antenna ter-minal, headphones terminal, microphone terminal, inputterminal, etc.) is 1M or greater. If it is less, the set mustbe inspected and repaired.Concerning important safetypartsMany of the electric and structural parts used in the sethave special safety properties. In most

12、 cases these prop-erties are difficult to distinguish by sight, and using re-placement parts with higher ratings (rated power andwithstand voltage) does not necessarily guarantee thatsafety performance will be preserved. Parts with safetyproperties are indicated as shown below on the wiring dia-gram

13、s and parts lists is this service manual. Be sure to re-place them with parts with the designated part number.(1) Schematic diagrams . Indicated by the z mark.(2) Parts lists . Indicated by the z mark.Using parts other than the designatedparts could result in electric shock, fires orother dangerous

14、situations.SAFETY PRECAUTIONSThe following check should be performed for the continued protection of the customer and service technician.LEAKAGE CURRENT CHECKBefore returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassisresistance check. If

15、the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of thepower cord is less than 460 kohms, the unit is defective.CAUTIONCAUTIONRadioFans.CN 收音机爱 好者资料库3DN-A300M、点検時注意願。注意事項守！特注意必要個所、 部品、 捺印注意事項表示。 注意書取扱説明書注意事項必守。感電注意！(1) 、交流電圧印加通電時内部金属部触感電。従通電時、絶縁使用手袋着用、部品交換、
