Test Mode
1. 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 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.9→No.15→No.10→No.11→No.12→No.13→No.14→No.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 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 displayed 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 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 Operation Display
Pressing Preset 1 Version (Date and time display)
Pressing Preset 3 CD (or TAPE with C/R models)
operating hours
Pressing Preset 5 CD (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 ejection 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 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 aor sis 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 4or ¢
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 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 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.)

CAUTION:For continued safety, replace safety critical components only with manufacturer’s recommended parts (refer
to, parts list). Indicates safety critical components.To reduce the risk of electric shock, leakage-current or resistance
measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance
is returned to the customer.
DC voltages are as measured with a high impedance voltmeter.Values may vary slightly due to variations between individual
instruments or/and units.

CAUTION:For continued safety, replace safety critical components only
withmanufacturer’srecommended parts(referto,partslist). Indicates
safety critical components.To reduce the risk of electric shock, leakage-

are acceptably insulated from the supply circuit) before the appliance is
returned to the customer.
DC voltages are as measured with a high impedance voltmeter.Values may
vary slightly due to variations between individual instruments or/and units.
