Pressing the ATT key ejects the cassette. 5. Audio functions Pressing the AUDIO key or the OPEN/CLOSE key on the remote controller initia

24、tes 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 displayed as “30”). LOUDNESS is OFF. The Bass/Treble Up/Down and Balance/Fader Up/Down buttons function as full

25、-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 on the remote controller can only be pressed shortly . (They cannot be held depressed.) With the models incor

26、porating 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.

28、: 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 Adjustment mode by resetting the unit while holding d + h. 2: Select the TUNER source by pressing SRC. 3: Whe

29、n 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 displayed values are those in the RAM.) 5: Vary each setting value using 4 or 6: Store the values in the correspondi

30、ng 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 the adjustment mode. The values set in the EEPROM will be read during the resetting. 9: When the band is swit

31、ched, 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 band. Notes 1: The items which are not stored will be set to the default values. 2: Once a value is stored in

32、memory, the value will always be used later. (It is not allowed to modify the setting values by switching the destination type.)
