Calibrating the Touchscreen
Calibrating the Touchscreen
The touchscreen simplifies and accelerates testing procedures by
providing immediate access to commands. It detects the position of your
finger or any other blunt pointing device, activating a command, function,
or button. The FTB-500 comes equipped with a stylus located in the top
right side of the unit.
When you receive your FTB-500, it will have been calibrated. However, if
you are used to work at a certain angle that could change the location of
the pointing device versus what the sensor detects, of if you feel that the
screen does not behave as you want, you can calibrate it again.
Note: If you are having trouble accessing the touchscreen calibration feature
because the touchscreen is not behaving as expected, use a USB mouse.
See Installing a Pointing Device on page 60 for details.
Note: To better see what is on the screen, you can also change the brightness of
the screen backlight, as explained in Changing the Backlight Level on
page 54.

MPORTANT
As it is the case for any computer, you can change the screen
resolution in the Windows Control Panel. However, be aware that
this will affect the performance and accuracy of the touchscreen.
The optimized resolution for using your touchscreen is of 800 x 600.
