Adjusting The Contrast; Calibrating The Touchscreen - Psion Teklogix 7545 User Manual

Adjusting The Contrast

Note: In addition to the manual adjustments described in this section, the display contrast
can also be adjusted using the Windows CE Control Panel. Refer to "Backlight" on
page 99 for details about this dialog box.
The display contrast can be adjusted from the unit keyboard using the [BLUE] key and func-
tion keys [F1] and [F2]. Pressing [F1]
lightens the display. Keep in mind that adjusting the contrast on a colour display is much
less pronounced than on a monochrome display.
To adjust the display contrast:
• Press the [BLUE] key twice to lock it on, and then press [F1]
or [F2]
• Once you've successfully adjusted the display contrast, remember to press the [BLUE]
key again to turn it 'off'.
Note: Contrast settings are optimized for the maximum readability. However, if the display
jitters or flickers, consider adjusting the contrast at power up.

Calibrating The Touchscreen

If your 7545 touchscreen has never been calibrated, or if you find that the stylus pointer is
not accurate when you tap on an item, use the Stylus Properties dialog box in the Control
Panel to recalibrate the screen.
• In the Control Panel, choose the Stylus icon to display the Stylus Properties window.
