LEAKAGE CURRENT CHECK Before returning the unit to the customer,

4、 make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

6、wall outlet. 2.Hold the following SPEAKER A 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 initialized Note: Note: If step 3

7、does not work, start over from step 1. Alluser 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 SPE
