Test mode specifications of cassette receiver Blank skip (B.S) is off. Pressing the ATT key ejects the cassette. 5. Audio functions Pressing the AUDI

25、O 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 displayed as “30”). LOUDNESS is OFF. The Bass/Treble

26、 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 on the remote controller can only be pressed short

27、ly . (They cannot be held depressed.) With the models incorporating RDS, the first operation in the menu becomes local seek. 7.

29、ent 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 Adjustment mode by resetting the unit while holdin

30、g 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 displayed values are those in the RAM.) 5: Vary each sett

31、ing 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 the adjustment mode. The values set in the EEPROM

32、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 band. Notes 1: The items which are not stored will

33、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.)
