5. Repeat the previous step two more times. Each time you touch the
+ you will hear a faint beep to indicate that the touch has been
accepted.
After the third time, your touchscreen will be calibrated.
Important
If you calibrated the touchscreen and the cursor moves
vertically when your finger moves horizontally on the screen or
vice versa, the touchscreen cable may not be connected to the
motherboard properly. Call a CTC customer support
representative. See Customer Support Services on page 5.
Adjusting the
Contrast
You may adjust the contrast on the PA PowerStation. The contrast is
a property of the LCD.
Note
The Brightness property is fixed and cannot be adjusted.
This property can be adjusted on the STN display only. So before you
begin, you will need to determine whether you own an STN or a TFT
display. To distinguish between the two types of displays, locate the
model number on the back of the PA PowerStation unit and compare
the third digit in the model number with the third digit in Table 4-1:
Display Type to determine the type of display you own.
