11) Select the data file which is to be copied (written) to the Flash

ROM installed to the ICU MAIN PWB Write socket in procedure
1).

– 1 – Double-click the Simulation Command List holder.

– 2 – Double-click the Special (Bear) holder.

– 3 – Double-clock the File Program Download.

– 4 – The message of "Program Download OK ?" is displayed.

Press the OK button.

– 5 – Select the data (PWB name) to be written and click the

START button.

– 6 – Select the data to be written and click the OPEN button.

With the above procedure, downloading (writing to the Flash
ROM) is started.

(NOTE) Selection of data files to be written determines whether a

source ROM (which includes the latest version program
and the Flash ROM copy program) or a ROM which has
only the latest version program is made.

12) Confirm that downloading (copying to the Flash ROM) is com-

pleted on the computer display and on the LCD display.
It normally takes 5 to 7 minutes to copy (write) to the Flash
ROM.

When downloading is normally completed, the following indica-
tions are shown.

*

The Read and Write LED’s on the ICU MAIN PWB are turned
off.

*

"THE PROGRAM WAS COMPLETE" is displayed on the
LCD.

13) Cancel the simulation 49-1 and turn off the power of the

machine.

(NOTE) If the Flash ROM is removed from or installed to the

machine with the machine power ON, the Flash ROM may
be destroyed. Be sure to turn off the power of the machine
before removing or installing the Flash ROM.

14) Remove the Flash ROM (which was upgraded) installed to the

ICU MAIN PWB Write socket in procedure 1).

When another Flash ROM is to be upgraded, install it to the ICU
MAIN PWB Write socket and turn on the power, and perform proce-
dures 11) through 14).

1) Check that the power of the machine is OFF. Install the Flash

ROM (of either of ICU MAIN PWB, PCU MAIN PWB, or operation
control PWB) to the ICU MAIN PWB Write socket.

2) Install the source Flash ROM (which has the program data of

either of ICU MAIN PWB, PCU MAIN PWN, or operation control
PWB) to the ICU MAIN PWB Read socket.

3) Turn on the power of the machine.

Copying is started. When copying is completed, the Read and the
Write LED’s on the ICU MAIN PWB are turned off.
It normally takes 30 to 60 sec to copy (write) to the Flash ROM.

4) Turn off the power of the machine, and remove the Flash ROM’s

from the Read and the Write sockets.

1) Installed the copied Flash ROM to the specified PWB.

2) Turn on the power of the machine and check that the machine

operates normally.

3) Use the simulation 22-5 to check each ROM version.

4) Install the shield plate and the stopper shift. (3 screws)

5) Attach the right upper cabinet of the machine. (2 screws)

The monitor displays before and after and during the Flash ROM
version up (copy) operation are shown below. If the Flash ROM ver-
sion up operation is not completed normally or if the Flash ROM is not
installed to the socket properly, a trouble code is displayed. In that
case, perform the countermeasures shown in the table below.

(1) ICU MAIN PWB monitor LED lighting specification

The monitor LED status during copy (write) operation of PC to
Flash ROM and Flash ROM to Flash ROM is shown below.
"Since, in the copy mode of Flash ROM to Flash ROM, the
machine status is indicated only with the monitor LED, there are
many monitor LED lighting patterns."
"While in the copy mode of PC to Flash ROM, the machine status
is indicated on the operation panel or on the PC monitor display,
there are less monitor LED lighting patterns."
