Note:
The main board holds the initial data.
So, data must be reset after replacing
the main board. Be sure to perform
initial data processing in the procedure
given below.
―Replacing main board―
When replacing the main board (FT10_9510), disconnect cables from connectors, loose 10
screws and remove the board (Figure 11). After replacing the main board, be sure to reconnect
the cables to the right destinations (see the wiring diagram).
―Initial data processing―
The initial data (FTflash.ini) is processed as shown in Figure 12.
FT10 board PC
When the software is started
with the FT10 board PC
connected, the initial data is
read from the board and
overwritten.

Rewriting data
Start the AP-7000 jig mode with the main board mounted.
Select [Hardware setting]→[System] and select [Configured data preservation] (Figure 13 (1)) to
create FTflashTmp.ini.
After replacing the main board, select [Configured data reading] (Figure 13 (2)) in jig mode,
select [Save and Exit] and start AP-7000.
―Replacing switching power supplies―
There are two switching power supplies (A and B), which are
mounted to the left side viewed from the chin rest of the main unit
(Figure 14).
When replacing switching power supply A, loosen three screws.
The support is not fixed, so be careful not to lose it. When
replacing switching power supply B, loosen four screws of (1),
remove the power supply unit together with switching power supply
B, and loosen four screws that fix it from backside.After
replacement, be sure to reconnect the cables to the right
destinations (see the wiring diagram).

―Replacing camera―
(1) Disconnect the cable, loosen screws and remove the camera
Disconnect the cable, loosen two screws and remove the camera unit (Figure 15).
(2) Adjust the camera
After replacing the camera, temporarily fix it because adjustment is required. Switch the main
unit power (be careful of electric shock) and move the camera back and forth for focusing
while viewing the monitor. When focusing, lift the lens frame, put a finger or another object
(Figure 16) or paste a piece of paper written with a letter, etc. Then, move the unit right and
left and stop it at the position of the best focus (Figure 17). After that, fine-tune the mirror
placed in front of the camera so that the cross-hair cursor of the camera is positioned at the
horizontal center of R of the lens holder (Figure 18).

―Replacing stimulus intensity sensor―
(1) Remove the stimulus intensity sensor together with its supporting plate
The stimulus intensity sensor is positioned under the left dome
viewed from the chin rest side. Remove the stimulus intensity
sensor connector, loosen two screws of the bottom plate, and
remove the unit (Figure 19).
(2) Remove the stimulus intensity sensor from the supporting plate
Loosen two screws of the supporting plate and remove the stimulus
intensity sensor (Figure 20).
(3) Mount and adjust the stimulus intensity sensor
Mount the stimulus intensity sensor by reversing steps (1) and (2) above. Before fixing the
supporting plate, align the supporting plate with its vertical stroke so that it is positioned in
the vicinity of the center of the dome hole and fix it. Then, align the stimulus so that the
amount of light on the acceptance surface becomes the highest level. (For details, see
Section 6 "Using Jig Software" on page 25.)
―Replacing background intensity sensor―
(1) Remove the background intensity sensor
The background intensity sensor is mounted under the
background LED viewed from the chin rest side.
First, disconnect the background intensity sensor connector,
loosen two screws and remove the sensor together with its
supporting plate (Figure 21).
(2) Mount and adjust background intensity sensor
Mount the background intensity sensor by reversing the removing steps. The board itself
needs no adjustment, but adjustment for recognizing the new sensor values is required. (For
details, see Section 6 "Using Jig Software" on page 25.)
