5. Step 5 Mode

The tracking servo is turned on, groove is traced, mute is set to off, and playback is started.  Even when the outermost
periphery of disc is reached in playback mode, it does not stop.  The LCD display indicates playback lapse time as in case
of regular CD playback.

When the following operation keys are pressed in this state, the following operations are performed.
"POWER" ................ The Test Mode is set to off, power is turned off, and the mode is changed to the regular standby mode.
"FF/FWD" ................ While this key is held down, the pickup slides to the external periphery.
"REW/REV" ............. While this key is held down, the pickup slides to the internal periphery.  However, if PU-IN is on, entry is

................................. invalid.

"PLAY" ..................... Invalid
"STOP" .................... Return to Step 1

Other cautions
• While the CD lid OPEN is detected, entry into any step later than Step 2 is disabled.  If CD lid OPEN is detected in any step

higher than Step 2, return to Step 1 is done.

• TOC IL is not performed in the Test Mode.
• The  key operation, excepting that specified above, is the same as that of regular operation (CD).  Only the FUNCTION key

is input-inhibited.

• Syncro REC with REC key input is also invalid in this mode.

1. Outline of tuner (radio) Test Mode

The tuner Test Mode is intended to store adjustment/measurement frequency in the preset memory CH without frequency
adjustment by the adjusting personnel when the tuner is adjusted in the production line.

2. Details of tuner Test Mode

When power is turned on with the POWER  key while the MEMORY/SET key and BAND key are held down together in
POWER OFF state, the frequency for adjustment/measurement of specific destination specified by the AREA terminal is
preset-stored in the preset memory CH (the frequency to be preset-stored for specific destination is explained in the Item
C).  When the tuner Test Mode is started up, it is started with FM.  FM is FM STEREO only.
When the REW key is pressed while the preset memory CH is 1CH, the highest CH is found as in case of regular mode.  When
the FF key is pressed while the preset memory CH is highest CH, 1CH is found.
The RADIO (TUNER) BAND key (or TUNER/BAND key on the remote controller) is valid.
As in case of regular mode, selection of band, FM MONO/STEREO mode is enabled by pressing the RADIO (TUNER) BAND
(or TUNER/BAND ) key.
Exiting the tuner Test Mode, When the destruction data is stored in the memory in the tuner Test Mode, AC supply is
interrupted in the Test Mode and the AC supply is recovered, all the memory is cleared with the destruction data  in case of
start-up.
(Countermeasures so that the Test Mode memory does not remain when AC supply is restored after power supply failure
occurred once in the Test Mode.)   The memory is not cleared when AC supply is turned off after POWER OFF and FUNCTION
selection.  In case of exit from the tuner Test Mode through the backup mode upon occurrence of

power failure

the frequency data stored in the preset memory for adjustment/measurement is erased.  (As a result the preset
memory CH becomes empty.)

The display indication is the same as that in case of regular operation.
The following display lights for one second when the tuner TEST mode is turned on

• The unit used in the table above is Hz.  K represents 1,000 times, and M represents 1,000,000 times.
• The hatched data shown in the table are not stored in the memory.
• FM is stereo mode.
Note: Keys which are effective in Test Mode

• Main unit keys:

VOLUME UP/DOWN, BAND, TUNING UP, POWER, MEMORY, CLEAR,
PRESET UP/DOWN

• Remote controller keys: VOL UP/DOWN, BAND, TUNING UP/DOWN, POWER, MEMORY, CLEAR, PRESET UP/DOWN

After the Test Mode is set, the following display lights for one second.

When this mode has been set, -14dB (STEP17) is set, the preset equalizer is set to FLAT (EQ-3), the SRS mode is set to OFF,
and the start-up function is set to Tape.
1. The display is the same as that indicated in case of regular operation excepting when Test Mode is set.
2. The volume control with the Volume UP/DOWN key is only the following 3 steps, differing from the volume control in the regular

operation mode.
Volume — 

∞

 (STEP 0)

Volume — 14dB (STEP 17)

Volume — 0 (STEP 24)

3. The preset equalizer and SRS are switched if key operation is performed.

When the Test Mode is set, the following display lights for one second.

The current time and timer time are set in the following procedure, and timer playback is performed.

1. The present time is set to 1:00, the timer is set to ON time 1:02, OFF time 1:12, Function is set to Tape, Volume is set to STEP8.
One minute is counted in increments of second, and timer playback is performed.  One step of Fade-in/out in this mode is
performed for 0.5 sec.
The display is the same as that appears in the regular timer operation.
2. After completion of timer playback test "TEST-5" indication (which appears when the mode is set) appears again and Standby
state is set.  PLAY key entry is waited.  If an entry is detected, the SLEEP timer is set to 2 minutes, and Function is set to Tape,
so that playback is started at once.  Volume is set to STEP8, and 10 seconds are counted down in decrements of second.  One
step of Fade-out is 0.5 sec.
The display is the same as that appears in the regular sleep playback mode.
3. After completion of SLEEP test, the Test Mode is turned off, and regular standby mode is set, so that the Test Mode ends.

When the LCD Test Mode is set, all the LCD segments light.

When the Test Mode is set, the following display appears.

In this Test Mode checking as to whether all the main unit keys can be detected is performed.  Accordingly, when this mode
is set, checking is performed so as to examine whether the POWER key was pressed last after  all the following keys were
pressed.  If the result is OK, the following OK is displayed.  If any one of keys was not pressed, an error is indicated.  When the
POWER  key is pressed, exit from the mode is made irrespective of whether the termination is normal or abnormal, and the
standby mode is set.
All the models using this microcomputer do not have the same keys.  The entry of the following keys is detected depending on
the combination of simultaneously pressed keys when this mode is set.  Key pressing order is not fixed.  Pressing of all keys
must be detected.

1. In case of "PLAY" + "REC PAUSE"

Since the model does not have RDS and SRS, all the keys to be detected are the following 11 keys.
PLAY, VOL   , VOL   , BAND, G-EQ, FUNCTION, MEMORY/SET, REC PAUSE, REW/REV, FF/FWD, STOP

OK/NG indication of test result must be as follows.
