Chapter 3: Getting To Know Your 7535
The Display
3.5 The Display
7535s are equipped with display backlighting to improve character visibility in low light conditions. The unit switches on when a key is pressed and the ambient light is below the set threshold. A light sensor on the front of the hand-held determines the ambient light level. On some displays, the contrast can also be adjusted to further improve character visibility.
3.5.1 Adjusting The Display Backlight
The behaviour of the display backlight – the ambient light threshold below which the backlight will become active and the intensity of the backlight – can be specified in the Display Properties dialogue box in the Windows CE Control Panel .
Note: Refer to “Display Backlight” on page 77 for details about the Display
Properties dialogue box.
3.5.2 Adjusting The Contrast On Monochrome Displays
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 “Display Contrast” on page 77 for details about this dialogue box.
On monochrome displays only, the display contrast can be adjusted from the unit keyboard using the <BLUE> key and function keys <F1> and <F2>.
To darken the display:
• Press the <BLUE> key, and then press <F1> . Repeat this key combination until the contrast suits your needs. To work more efficiently with these keys, refer to the note below.
To lighten the display:
• Press the <BLUE> key, and then press <F2> . Repeat this key combination until the contrast suits your needs. To work more efficiently with these keys, refer to the note below.
Note: To adjust the display contrast quickly, lock the <BLUE> key “on” by pressing it twice. You can then press the <F1> and <F2> function keys until you can easily read the contents of the screen.
When you have satisfactorily adjusted the contrast, press the <BLUE> key a third time to unlock or turn it off.
