How to enter test mode While holding the FM key and preset 6 key, reset the unit. All display segments light up when the test mode is

23、 entered. 2. How to exit from test mode Reset the unit. The test mode is not terminated by turning ACC off, power off, momentary power down or panel detaching. 3. Test mode specifications of CD receiver Pressing the Track Up key jumps to tracks in the following sequence: No.9No.15No.10No.11No.12No.1

24、3No.14No.9 (Repeats the cycle) Pressing the Track Down key jumps to the track immediately 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

25、 the cassette. 5. Audio functions Pressing the AUDIO key or the OPEN/CLOSE key on the remote controller initiates the Audio mode. In the Audio adjustment mode, the Seek Up/Down keys on the remote controller can only be pressed shortly. (They cannot be held depressed.) The volume is 10 dB (which is d

26、isplayed as “30”). LOUDNESS is OFF. The Bass/Treble Up/Down and Balance/Fader Up/Down buttons function as full-boost/full-cut and full-front/full-rear respectively. 6. Menu mode Pressing the CLK or the DNPP key on the remote controller initiates the Menu mode. In the Menu mode, the Seek Up/Down keys

27、 on the remote controller can only be pressed shortly . (They cannot be held depressed.) With the models incorporating RDS, the first operation in the menu becomes local seek. 7. Version and operating hours display The following table shows the key operations and resulting display information. Key O

28、perationDisplay Pressing Preset 1Version (Date and time display) Pressing Preset 3CD (or TAPE with C/R models) operating hours Pressing Preset 5CD (or TAPE with C/R models) ejection count Holding Preset 3 while the operating hour information is displayed clears it. Holding Preset 5 while the ejectio

29、n count information is displayed clears it. Adjustment Mode Adjustable items 1: Stereo Decoder Subaddress: 9 2: Configuration Subaddress: D Default values If they are not written in the EEPROM, the default values specified by the IC developer are set in IC2-3. Adjustment procedure 1: Enter the IC2-3

30、 Adjustment mode by resetting the unit while holding d + h. 2: Select the TUNER source by pressing SRC. 3: When the adjustment mode is entered, the display shows a 2-digit hex number. 4: When preset a or s is recalled, the setting values corresponding to the pressed number are displayed. (The displa

31、yed 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. (It is not required to store all the values together.) 8: After storing the values, reset the unit to exit from

32、 the adjustment mode. The values set in the EEPROM will be read during the resetting. 9: When the band is switched, there may be cases in which the preset number being displayed does not coincide with the stored setting value. To check this , be sure to recall the preset number after you switch the

33、band. Notes 1: The items which are not stored will be set to the default values. 2: Once a value is stored in memory, the value will always be used later. (It is not allowed to modify the setting values by switching the destination type.) ABCDEFGIH 1 2 3 4 5 6 7 78 Refer to the schematic diagram for

34、 the values of resistors and capacitors.
