3、 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 electric shock!(1) An AC vo

4、ltage 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 cord when replacing parts,

5、 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 could cause injury if fingers

6、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 important safety parts that

7、 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 surface of printed circuit

8、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 removed or discon-nected for ser

9、vicing 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 thatsafety is ensured.(Insulat

10、ion 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 exposed metal parts (antenna

11、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 cases these prop-erties ar

12、e 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-grams and parts lists is this s

Indicated by the z mark.Using parts other than the designatedparts could result in electric shock, fires orother dangerous situations.SAFETY PRECAUTIO

14、NSThe 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 the leakage current exceeds

15、 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3AVR-4310CI/AVR-4310/AVC-4310DIMENSIONAVR-4310CI/AVR-4310/AVC-431034443415515.5170.520.7244.5372.820.541454.74AVR-4310CI/AVR-4310/AVC-4
