in POWER OFF state and turn on the power by the use
of "ON/STAND BY" button to preset and store frequency
for adjustment and measurement of destination specified
by the AREA terminal in the preset memory CH. However,
Ordinary 1 and Ordinary 2 are stored in the destinations
when the test mode is obtained.
(As for frequencies to be preset and stored for each
destination, refer to item 3.)
The tuner test mode is started from preset No.1.
The operations of test mode are identical with the ordinary
operations of TUNER function. FUNCTION switching is
invalid.
It is necessary to discard the content of preset memory
when the tuner test mode is ended; be sure to write "0000"
or "1111" bits in the memory to be checked for judging
memory error at initial setting and to initialize memory.
When the tuner test mode is obtained, the following display
lights for one second.
• The TUNER TEST 2 mode is obtained with >> + MEMORY/
SET + ON/STAND-BY. ->Turn off AC in the TEST 2 mode
to restore the initial state.
Turn off POWER to protect the memory of TEST 2 mode.
Turn off POWER again to obtain the ordinary operation
while the data is stored in the memory (besides TUNER).
If AC OFF state is maintained in this state for about 1/2 day,
start is executed in the initial state.
• To clear the whole memory, insert the AC cord, pressing
MEMORY/SET + CD PLAY.

7. Button input diagnosis Test Mode (TEST 6)
When the test mode is obtained, the following is displayed.
(STAND-BY AND DEMO OFF STATUS)
This test mode is intended to check whether all the main
unit buttons can be detected. Accordingly, in this test
mode, it is checked whether the "ON/STAND BY" button
was pressed after all the buttons shown below were pressed.
If the result is OK, OK is displayed. If any one of keys was
not pressed, an error is displayed. In both cases of OK
termination or error termination, the mode is shifted to the
standby mode if the "ON/STAND BY" button is pressed
subsequently.
All models using this type of microcomputer are not always
provided with the same buttons. Since the buttons used are
different depending on models, types of buttons to be used
are determined by whether SURROUND, and an electric lid
are available at the initial setting by MODEL port.
The order of buttons to be pressed is not determined.
Accordingly, it is checked whether all buttons have been
pressed.
1. PU-IN buttons: REW/PRESET DOWN + CD STOP
Since this model is provided with SURROUND (HAVE
OR NOT), and electric CD lid, the following 10 buttons
are detected as all buttons.
PLAY, X-BASS/DEMO, FUNCTION, VOLUME UP/
DOWN, MEMORY/SET, REW, FF, STOP, CD-OPEN/
CLOSE
The OK/ERROR display of test result is as follows.

Yes
No
The HF waveform is normal and the time is displayed
normally, but no sound is produced. Or the sound
has dropouts.
(5) Others.
There are too many error flags on a damaged disc which
makes error correction impossible.
Check again using a known good disc.
