How to enter test modeWhile holding the FM key and preset 6 key, reset the unit.All display segments light up when the test mode is entered.2. How to exit from test modeReset the unit.The test mode is not terminated by turning ACC off, poweroff, momentary power down or panel detaching.3. Test mode specifications of CD receiver Pressing the Track Up key jumps to tracks in the followingsequence:No.9No.15No.10No.11No.12No.13No.14No.9(Repeats the cycle) Pressing the Track Down key jumps to the trackimmediately before the track being played. Pressing Preset 1 key jumps to track No. 28. Forced ejection is not provided.4. Test mode specifications of cassette receiver Blank skip (B.S) is off. Pressing the ATT key ejects the cassette.5. Audio functions Pressing the AUDIO key or the OPEN/CLOSE key on theremote controller initiates the Audio mode. In the Audio adjustment mode, the Seek Up/Down keyson the remote controller can only be pressed shortly. (Theycannot be held depressed.) The volume is 10 dB (which is displayed as “30”). LOUDNESS is OFF. The Bass/Treble Up/Down and Balance/Fader Up/Downbuttons function as full-boost/full-cut and full-front/full-rearrespectively.6. Menu mode Pressing the CLK or the DNPP key on the remote controllerinitiates the Menu mode. In the Menu mode, the Seek Up/Down keys on the remotecontroller can only be pressed shortly . (They cannot beheld depressed.) With the models incorporating RDS, the first operation inthe menu becomes local seek.7. Version and operating hours display The following table shows the key operations and resultingdisplay information.Key Operation DisplayPressing Preset 1 Version (Date and time display)Pressing Preset 3 CD (or TAPE with C/R models)operating hoursPressing Preset 5 CD (or TAPE with C/R models)ejection count Holding Preset 3 while the operating hour information isdisplayed clears it. Holding Preset 5 while the ejection count information isdisplayed clears it.Adjustment ModeAdjustable items1: Stereo Decoder Subaddress: 92: Configuration Subaddress: DDefault valuesIf they are not written in the EEPROM, the default valuesspecified by the IC developer are set in IC2-3.Adjustment procedure1: Enter the IC2-3 Adjustment mode by resetting the unit whileholding d + h.2: Select the TUNER source by pressing SRC.3: When the adjustment mode is entered, the display shows a2-digit hex number.4: When preset a or s is recalled, the setting valuescorresponding to the pressed number are displayed. (Thedisplayed values are those in the RAM.)5: Vary each setting value using 4 or ¢6: Store the values in the corresponding preset number.7: The settings can be performed individually for each item. (Itis not required to store all the values together.)8: After storing the values, reset the unit to exit from theadjustment mode. The values set in the EEPROM will beread during the resetting.9: When the band is switched, there may be cases in whichthe preset number being displayed does not coincide withthe stored setting value. To check this , be sure to recall thepreset number after you switch the band.Notes1: The items which are not stored will be set to the defaultvalues.2: Once a value is stored in memory, the value will always beused later.(It is not allowed to modify the setting values by switchingthe destination type.)A B C D E F G IH12345677 8Refer to the schematic diagram for the values of resistors and
