bration process and return to the
"Screen Calibration" screen.
Press the [Enter] key to close the
error dialog. (Not normally needed.)

[CLR screen] button to remove all the lines.
The [Cursor on/off] button cannot be used.

pleting the calibration process, and returns you
to the "Screen Calibration" screen.
If the calibration is not performed
carefully, or the [Enter] key is pressed
ATTENTION

been touched, the following error
message may appear:
Parameter Error. Please input, again
Press the [Enter] key to dismiss the
error dialog, and perform the calibra-
tion again, being careful to touch each
calibration point accurately.
