TOUCH PANEL CALIBRATION

Define the coordinates used in this sheet.
4.3.3.7.1 Touch adjustment (TOUCH ADJUST)
The 4 points on the screen, P1 (X1,Y1), P2 (X2,Y2), P3 (X3,Y3),
P4 (X4,Y4) are the coordinate values (voltage values) actually
read by touch adjustment.
The points shown on the adjustment screen have 2 dots, one for
X and one for Y coordinate.
In normal mode touch adjustment, P2 and P4 coordinates are ac-
quired. In test mode touch adjustment, coordinates of P1 to P4
are acquired (The reference point is lower left, whose coordinate
value shall be (1,1).

4.3.3.8 VER/CHECK SUM
Performs check on the version number of each micro-controller/
data and the SUM value of the APP program area/DATA area.
Select this item after inserting a USB device containing the check
data for all of the above.
For details on the data format for checking, refer to "About Data
for VER/CHECK SUM Checking".
(1) Version Number Check
Determines whether the version number retained within the
set is consistent with that read from the USB device.
If the version number is consistent, display "OK" to the left
of the version display. If it is not consistent, display "NG".
Perform version check on all items on SS Mode Page2/3
marked with "OK".
Consistent: "OK: 1.00.00"
Not consistent: "NG: 1.00.00"
Not checked: "1.00.00"
*Each time this item is selected, the latest result will be dis-
played.
(2) SUM Value Check
Calculate the SUM value for each of the APP program area
and DATA area, and determine whether they are consis-
tent with the SUM value read from the USB device.
If the value is consistent, display OK + SUM value. If it is
not consistent, display NG + SUM value.
*Exclude DATA area for DOP (DATA1, DATA2, DATA3)
from SUM calculation.

ASUM OK ********(SUM value 4 bytes) ← Upper line shows
CHKSUM result of program area
DSUM OK ********(SUM value 4 bytes) ← Lower line shows
CHKSUM result of DATA area
<CHKSUM NG (NG only for Data Area)>
ASUM OK ********(SUM value 4 bytes) ← Upper line shows
CHKSUM result of program area

(3) TOTAL Assessment
Display TOTAL as OK only if all version checks and SUM
values are OK, and all monitor adjustment, touch panel ad-
justment, and S meter adjustment are complete.
Display as NG if any one of these is NG.
