If this happens, execute the following pro-cedure to reset the microcomputer and return the unit to itsnormal operating condition.For U.S.A. and CanadaUnplug the power cord from the wall outlet, thenplug it back in while holding down the POWER key.Except for U.S.A. and CanadaWith the power cord plugged in, turn the POWER keyOFF. Then, while holding down the ON/STANDBYkey, press the POWER key. Please note that resetting the microcomputer will clearthe contents of the memory and returns the unit to thestate it was in when it left the factory.CautionsRadioFans.CN 收音机爱 好者资料库AR-404/KRF-A4030/A4030E/A4030-S3CIRCUIT DESCRIPTION1.

All functions are initialized and activated in the all light-ing mode. All lighting mode is canceled when any main unitskeys are pressed. The normal display obtained whenthe selector is set to TUNER then appears. E2PROM check(Etype only).Check the reading data and the writing data of theE2PROM after setting the test mode.Display shows blank if the reading data and writingdata are the same. Display shows LW if the differentdata will be written to E2PROM.3-4 ACTIVE CONTENTS The mute control is not activated when the mode isswitched. The test mode will be terminated by plugging it off thepower source or by initializing it when all the settingswill be initialized. During the test mode, it can be operated in a specialmanner that is deferent from an ordinary operation byusing the keys on the remote control or the main body,specifically as shown in the following table (3-5 CON-TENTS). Channel space will be no changed in the test mode.3-5 CONTENTS 3-5-1 TUNER FUNCTIONWITH THE SELECTOR ON TUNER (E TYPE ONLY)DESTINA-TIONTUNERTYPEBANDRECEIVINGCHANNELSPACEIFPLLREFERENCEFREQUENCYRANGEFREQUENCYDSW3(D507)DSW2(D505)DSW1(D504)DSW0(D510)K,PK1(1700)FMAM87.5MHz108.0MHz530kHz1700kHz100kHz10kHz+10.7MHz+450kHz25kHz10kHz0000M,XE1FMAM87.5MHz108.0MHz531kHz1602kHz 50kHz9kHz+10.7MHz+450kHz25kHz9kHz0011MK2(1600)FMAM87.5MHz108.0MHz530kHz1610kHz100kHz10kHz+10.7MHz+450kHz25kHz10kHz0001EE3RDSFMAM87.5MHz108.0MHz531kHz1602kHz 50kHz9kHz+10.7MHz+450kHz25kHz9kHz0101DSW0DSW3(DIODE SW)* 0: NONE DIODE,1:ADD DIODE2.
