After the pause, reconnect the AC powercord and check the units operation. If the systemstill malfunctions, a system reset may clear theproblem.To clear the AVR 7500s entire system memoryincluding tuner presets, output level settings,delay times and speaker configuration data, firstput the unit in Standby by pressing the SystemPower Control button 2. Next, press theTone Mode8and the RDSbuttons simul-taneously.The unit will turn on automatically and displaythe RESET message in the MainInformation Display Y.Note that once youhave cleared the memory in this manner,it is nec-essary to re-establish all system configurationsettings and tuner presets.NOTE: Resetting the processor will erase anyconfiguration settings you have made for speak-ers, output levels, surround modes, digital inputassignments as well as the tuner presets.After areset the unit will be returned to the factory pre-sets, and all settings for these items must bereentered.If the system is still operating incorrectly, theremay have been an electronic discharge or severeAC line interference that has corrupted the mem-ory or microprocessor.If these steps do not solve the problem, consultan authorized Harman Kardon service depot.SYMPTOMCAUSESOLUTIONUnit does not function when Main No AC Power Make certain AC power cord is plugged Power Switch 1is pushedinto a live outlet Check to see if outlet is switch controlledDisplay lights, but no sound Intermittent input connections Make certain that all input and speaker or pictureconnections are secure Mute is on Press Mute button ?
