Adjusting The Contrast
3.5.2 Adjusting The Contrast
Note: In addition to the manual adjustments described in this section, the dis-
play contrast can also be adjusted using the Windows CE Control Panel.
Refer to “Display Contrast” on page 88 for details about this dialogue
box.
The display contrast can be adjusted from the unit keyboard using the <BLUE> key
and function keys <F1> and <F2>. Pressing <F1> darkens the display, and
pressing <F2> 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> . to
darken the display or <F2> . to lighten the display.
• Once you’ve successfully adjusted the display contrast, remember to press
the <BLUE> key again to turn it ‘off’.
3.5.3 Calibrating The Touchscreen
If your 7535 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 dialogue box in
the Windows CE Control Panel to recalibrate the screen.
• In the Control Panel, choose the Stylus icon to display the Stylus Properties window.
