• SW1-2, SW1-3, and SW1-4
These switches are used in various combinations to control the backlight
brightness used at start-up, automatic dimming, and automatic switch-off of the
backlight after 2.5 and 5 minute intervals of no SIO communication or touch
panel operation.
Once SIO communication or touch operation is performed, the backlight is
returned to its initial condition.

Note:
• When the FP receives a display-related SIO command from the host,
the backlight’s automatic brightness reduction/power-off functions
are canceled.
• To perform simultaneous keyboard and touch panel operation, do
not enable the backlight’s automatic dimming/switch-off functions,
since during keyboard operation these functions cannot be activated.
• SW1-5
This switch is used to enable recalibration of the PS/2 mouse compatible
output mode (when the SW 1-1 is ON). This feature allows the User to correct
any displacement that way have developed between the screen's displayed
position and the actual touch position.
Use the following steps to recalibrate the screen:
1) Set the SW1-5 switch to ON to start the recalibration mode. (The FP's
buzzer sounds, and stops touch panel data output)
2) Press the upper right corner of the display.
3) Press the lower left corner of the display.
In calibration mode, removing your finger
from the screen will enable that position and
cause a short beep to sound.
When the input is incorrect (due to the
procedures being performed out of order,
etc.) a warning beep will sound and the unit
will wait for the correct input.
4) Set the SW1-5 switch to OFF to quit the recalibration mode. (The FP
stores the calibration data, sounds the buzzer, and re-starts touch panel
data output)
The buzzer will sound continuously while the calibration data is
being saved. While the buzzer is sounding, do not reset the unit or
turn it OFF.
