Be sure to heed these cautions and thecautions indicated in the handling instructions.Caution concerning 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 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 could 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 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 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 removed 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 thatsafety 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 exposed 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 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-grams 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 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 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3AVR-3310CI/AVR-3310/AVR990/AVC-3310DIMENSIONAVR-3310CI/AVR-3310/AVR-990/AVC-331034443415515.5170.520.7244.5372.820.541454.74AVR-3310CI/AVR-3310/AVR990/AVC-3310WIRE ARRANGEMENTIf wire bundles are untied or moved to perform adjustment or parts replacement etc., be sure to rearrange them neatly asthey were originally bundled or placed afterward.Otherwise, incorrect arrangement can be a cause of noisegeneration.Wire arrangement viewed from the topExcept AVR-3310CI, AVR-990 modelsdFront Panel sideBack Panel side5AVR-3310CI/AVR-3310/AVR990/AVC-3310CAUTION IN SERVICINGBefore the Digital P.W.B. are replacedIf you cannot specify the cause of the digital PWB defect, carry out Initializing Update to latest firmware. The defect may be cleared. See the following for the method of initializing the com.Initializing AV SURROUND RECEIVERAV SURROUND RECEIVER initialization should be performed when the com, peripheral parts of com, and Digital P.W.B. are replaced.1. Switch off the unit.2. Hold the following STANDARD button and DSP SIMULATION button, and switch on the unit.3. Check that the entire display is flashing with an interval of about 1 second, and release your fingers from the 2 buttons and the microprocessor will be initialized.Note:If step 3 does not work, start over from step 1. All user settings will be lost and this factory setting will be recovered when this initialization mode.So make sure to memorize your setting for restoring after the initialization.JIG to use for servicingWhen you repair the printing board, you can use the following JIG.
