The lightening flash with arrowhead symbol,
within an equilateral triangle, is intended to
alert the user to the presence of uninsulated
“dangerous voltage” within the product's enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the literature
accompanying the appliance.
“WARNING”
“TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK,
DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.”

An appliance and cart combination should be moved with
care. Quick stops, excessive force, and uneven surfaces
may cause the appliance and cart combination to overturn.
Wall or Ceiling Mounting - The appliance should be
mounted to a wall or ceiling only as recommended by the
manufacturer.
Ventilation - The appliance should be situated so that its
location or position does not interfere with its proper ventilation. For example, the appliance should not be situated on a bed, sofa, rug, or similar surface that may block
the ventilation openings; or, placed in a built-in installation, such as a bookcase or cabinet that may impede the
flow of air through the ventilation openings.
16.
17.
Heat - The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including amplifiers) that produce heat.
Power Sources - The appliance should be connected to a
power supply only of the type described in the operating
instructions or as marked on the appliance.
Grounding or Polarization - The precautions that should
be taken so that the grounding or polarization means of
an appliance is not defeated.
Power Cord Protection - Power supply cords should be
routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.
Cleaning - The appliance should be cleaned only as recommended by the manufacturer.
Nonuse Periods - The power cord of the appliance should
be unplugged from the outlet when left unused for a long
period of time.
Object and Liquid Entry - Care should be taken so that
objects do not fall and liquids are not spilled into the enclosure through openings.
Damage requiring Service - The appliance should be serviced by qualified service personnel when:
A. The power supply cord or the plug has been damaged;
or
B. Objects have fallen, or liquid has been spilled into the
appliance; or
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate normally or
exhibits a marked changed in performance; or
E. The appliance has been dropped, or the enclosure
damaged.
Servicing - The user should not attempt to service the appliance beyond that described in the operating instructions. All other servicing should be referred to qualified
service personnel.

3. SOFTWARE UPDATE
The FD-4 software can be updated through SCSI port. This means that unscrewing and opening up the FD-4 top panel is not
necessary to change the EPROMs on the MAIN PCB assy. Please refer to the following explanation for correct software
updating procedures.
3-1. Method of Sending Software from Fostex Japan
There are two ways of sending the FD-4 updated software.
1. Updated software in a removable media (e.g. floppy disk, zip disk, etc.) to be sent via airmail
2. Updated software as an attachment file to be sent via E-mail
3-2. Required Tools
The following tools/equipment are required to update the FD-4 software.
1.
2.
3.
4.
IBM PC compatible computer with SCSI board
Removable type SCSI drive
Cable between the removable type SCSI drive and the SCSI board
Cable between the removable type SCSI drive and the FD-4 (D-SUB 25-pin)
3-3. Software Updating Procedures
Presuming that the updated software is correctly sent and is copied into your computer.
1.
2.
3.
4.
5.
6.
7.
Connect the removable type SCSI drive to the SCSI board.
Insert the diskette to the removable type SCSI drive and format it by the computer (IBM PC format).
Copy the updated software file to the removable type SCSI drive (diskette).
Reconnect the removable type SCSI drive to the FD-4 SCSI port.
In order to boot up the FD-4 system software, insert the diskette formatted by the FD-4.
Eject the diskette by pressing the EXIT/NO key while holding down the SHIFT key.
Insert the diskette with updated software file. The FD-4 LCD display shows “No Disk”, “Initial..”, “name of drive (e.g.
ZIP 100)” and “FD4MOT” in order and comes to a standstill at the display below.

8. Pressing the EXECUTE/YES key would update the software. The display shows “Loading!”, “Writing!” and “Initial..”
in order and automatically returns to the above condition again. This indicates that updating the software is completed.
9. Eject the diskette with updated software file and insert the diskette formatted by the FD-4.
10. Check the software version by the Service Mode. (For details, please refer to the section “4-2. Software/CPU version”.)
CAUTION:
1. The diskette in which the updated software file is copied must be formatted by IBM PC computer, not by Macintosh.
2. If something wrong happens while updating the software (e.g. A blackout occurred while updating the software.), the
FD-4 might not be able to boot up the system software inside the Flash ROM. In this case, please refer to the section “48. Flash ROM” (page 17).

CAUTION:
1. There might be a case that the percentage display does
not indicate “0.0%” exactly when the FD-4 is working as
a slave machine and is synchronizing with a master
machine. This is caused by a difference of internal clock
between both machines but there is nothing wrong with it.
2. The two-digit numbers displayed in the right of percentage

programming purpose.

This mode is used when copying the system software from
EPROMs to Flash ROM.
As mentioned in the section “SOFTWARE UPDATE”, the
FD-4 software inside the Flash ROM can be updated through
SCSI port. However, if something wrong happens when
updating the software (e.g. A blackout occurred while
updating the software.), the FD-4 might not be able to boot
up the system software inside the Flash ROM.
In this case, the following procedures must be taken.
1.
2.
3.
4.
Turn the switch S1 on the MAIN PCB assy to “EPROM” side.
Mount and solder the EPROM sockets to “U31” and “U32” on the MAIN PCB assy.
Plug the EPROMs into the sockets.
Turn on the power of FD-4.
In this condition, the FD-4 is booted up using the system software inside the EPROMs. The next procedures to take are as
follows.
1. Put the FD-4 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-4 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.
4-9. Event Number
Individual Audio Files are continuously recorded in each track of program on the FD-4. However, the FD-4 disk
management system allows to create a “no signal recorded” section between Audio Files. This “no signal recorded”
section is handled as “Zero File”. As shown in the diagram below, Audio Files and Zero Files will be alternately recorded
on the FD-4 and each Audio File and Zero File are counted as individual “Event”. Thus, the number of events on a certain
track is calculated by summing up these Audio Files and Zero Files. Each track can accommodate up to 512 events but the
FD-4 will not newly record events when the number of events reach 508.
