The example on the left indicates that the CPU version is
V1.00 and its programming date is January 19, 1998.
This mode test the signal flow from the DATA INPUT jack
to the D/A converter. A S/P DIF digital signal whose
sampling frequency is the same as the one when formatting
the diskette (MASTERING MODE 1, 2: 44.1kHz,
NORMAL MODE: 32kHz) must be input to the DATA
INPUT jack.
To execute this test, press the EXECUTE/YES key while
"?" is blinking.
If the FD-4 is in a normal condition, "32kHz or 44.1kHz"
and "DIGITAL" will be lit solid. The odd (1 and 3) and
even (2 and 4) channels indicate the L and R input level of
S/P DIF digital signal fed to the DATA INPUT jack
respectively.
If the FD-4 is not in a normal condition, "32kHz or 44.1kHz"
and "DIGITAL" will blink and the bargraph meter will not
indicate any input level.
This mode tests if all the segments on the LCD display and
the LEDs on the FD-4 top panel are correctly working or
not.
To execute this test, press the EXECUTE/YES key while
"?" is blinking.
If the FD-4 is in a normal condition, all the segments on the
LCD display will lit solid and the LEDs on the top panel
will start blinking.

If the FD-4 is not in a normal condition, the faulty segments
on the LCD display and/or LEDs on the top panel will remain
unlit.
