4、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.(1) (2) 500V1M(1) (2) RadioFans.CN 收音机爱 好者资料库33AVR-1604/684 / AVC-1580CAUTION

5、IN SERVICING Initializing AV SURROUND RECEIVERInitializing AV SURROUND RECEIVERAV SURROUND RECEIVER initialization should be performed when the mcom, peripheral parts of mcom, and DSP P.W.B. are replaced.1.Switch off the unit and remove the AC cord from thewall outlet.2.Hold the following SPEAKER A

6、button and SPEAK-ER B button, and plug the AC cord into the outlet.3.Check that the entire display is flashing with aninterval of about 1 second, and release your fingersfrom the 2 buttons and the microprocessor will be initializedNote: Note: If step 3 does not work, start over from step 1. Alluser

7、settings will be lost and this factorysetting 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 AV 初期化周辺部品、DSP 基板等交換場合、AV 初期化行下。1.電源押状態、壁電源電源抜。2.SPEAKER A SPEAKER B 同時押、電源差込。3. 表示約 1 秒間隔点滅確認後、2 指離。初期化。注意 :注意 :上記
