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.(1)(2)500V1M(1)(2)RadioFans.CN 收音机爱 好者资料库3AVR-3806 / AVC-3920DIMENSION028.5182.5150172172217217066.188.2244.5318.1338.84AVR-3806 / AVC-3920WIRE ARRANGEMENTIf wire bundles are untied or moved to perform adjustment or parts replacement etc.,be sure to rearrange them neatly as they were originally bundled or placed afterward.Otherwise, incorrect arrangement can be a cause of noisegeneration.Wire arrangement viewed from the top整形図調整部品交換等、類結束移動場合、作業完了時点整形。正整形発生原因。上面整形Front Panel sideBack Panel side5AVR-3806 / AVC-3920CAUTION IN SERVICING 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 NIGHT button and PURE DIRECT 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.時注意事項AV 初期化周辺部品、Digital 基板等交換場合、AV 初期化行下。1.
