: blinking
The example on the left indicates that the Flash ROM version
is V1.00 and its programming date is September 5, 1998.
In this condition, by turning the jog dial C.W. or C.C. W.,
the CPU version can be checked.
The example on the left indicates that the CPU version is
V2.00 and its programming date is August 4, 1998.
This mode tests the signal flow from the DATA INPUT jack
to the D/A converter. A S/P DIF digital signal (Fs: 44.1kHz)
must be input to the DATA INPUT jack to execute this test.
Then, press the EXECUTE/YES key while “?” is blinking.
If the FD-8 is in a normal condition, “44.1kHz” and
“DIGITAL” will be lit solid. The odd (1, 3, 5, 7 and L) and
even (2, 4, 6, 8 and R) channels indicate the left and right
input level of S/P DIF digital signal fed to the DATA INPUT
jack respectively.
If the FD-8 is not in a normal condition, “DIGITAL” will
blink and the bargraph meter will not indicate any level.
13
FD-8
4-4. Display/Button Test
: blinking
This mode tests if all the segments on the LCD display, LEDs
and buttons (switches) on the FD-8 top panel are correctly
working or not.
To execute this test, press the EXECUTE/YES key while
“?” is blinking.
If the FD-8 is in a normal condition, all the segments on the
LCD display will be lit solid and all the LEDs on the top
panel will start blinking.
?
If the FD-8 is not in a normal condition, faulty segments on
the LCD display and/or LEDs on the top panel will remain
unlit.
In this condition, if the EXECUTE/YES key is pressed one
more time, the Button Test can be executed.
The Button Test checks if each key/button and jog dial are
working properly or not. The display on the left indicates
that the RECORD button is pressed and held down. (“K”
stands for the Key and “J” the Jog dial.)
The display on the left indicates the condition when the jog
dial is turned C.W.
The table below shows the relationship between the key/
button/jog dial and the corresponding numbers appear on
the LCD display.
In order to quit the Button Test, turn the jog dial C.W. or
C.C.W. further after “J_20” or “J-19” is displayed
respectively.

CAUTION:
1.
If both the external SCSI drive and the internal 2.5” EIDE hard disk drive are connected at the same time, the
: blinking
SCSI drive is given priority over the 2.5” E-IDE hard
disk drive and is recognized by the FD-8.
2.
Up to 2 x SCSI drives can be connected to the FD-8. One
is for recording / reproducing (SCSI ID: 0 ~ 5) and the
?
other for exclusive backing up (SCSI ID: 6). Initializing
is possible on the SCSI drive (ID: 0 ~ 5) used for recording
/ reproducing only.
After pressing the EXECUTE/YES key, “SURE?” will start
blinking in the LCD display. In this condition, pressing the
EXECUTE/YES key one more time would initialize the
recognized disk drive.
This mode puts the disk back to the condition originally
formatted.
4-8. Flash ROM
: blinking
In this case, the following procedures must be taken.
1.
Turn the switch S1 on the MAIN PCB assy to “EPROM” side.
2.
Mount and solder the EPROM sockets to “U31” and “U32” on the MAIN PCB assy.
3.
Plug the EPROMs into the sockets.
4.
Turn on the power of FD-8.
In this condition, the FD-8 is booted up using the system software inside the EPROMs. The next procedures to take are as
follows.
1.
Put the FD-8 into the Service Mode, select “FlashROM” and press EXECUTE/YES key. (“SURE?” is blinking.)
2.
Press the EXECUTE/YES key one more time to copy the system software from EPROMs to Flash ROM.
3.
Turn the switch S1 to “FLMEM” side.
4.
In order to confirm that the FD-8 is booted up using the system software inside the Flash ROM, turn off the power,
disconnect the EPROMs and turn the power back on again.
5.
After the confirmation, update the system software inside the Flash ROM through SCSI port again.
This mode is used when copying the system software from
EPROMs to Flash ROM.
As mentioned in the section “SOFTWARE UPDATE”, the
FD-8 software inside the Flash ROM can be updated through
the SCSI port. However, if something wrong happens when
updating the software (e.g. A blackout occurred while
updating the software.), the FD-8 might not be able to boot
up by the system software inside the Flash ROM.

FD-8
4-10. Free Block Check
: blinking
This mode is used to check the condition of the diskette
inserted into an external SCSI drive connected to the FD-8
or the internal E-IDE hard disk drive. (As mentioned before,
the SCSI drive has a priority unless the SCSI ID is set to
“6”.)
If the Free Block indicates a large number even after
formatting and no signal is recorded or recorded signals are
frequently skipped, the diskette / hard disk drive can be
judged to be in a bad condition.
4-11. Test 1
: blinking
This Service Mode is exclusively designed for software
programming purpose. There is nothing to do with servicing
/ repairing the FD-8.

5. ERROR CODE LIST
The chart below indicates the error code number and corresponding description. Since the error code list is basically
designed for our engineers to improve the software, the description is quite technical. If you find the FD-8 with one of the
error codes displayed, we encourage you to update the software first. In case updating the software does not solve the
problem, we would like you to inform us about details.
