from the numeric keys [2], [3] and [4].

Press [3] to type 'd', and press [4] to type the letter 'g'.

To end alpha selection, press the [ORANGE] key again to unlock it.

The Keypad Backlight
The intensity of the keypad backlight and the conditions under which this backlight is acti-
vated can be configured using the Keyboard icon in the Windows CE Control Panel. The
behaviour of the keypad backlight is tailored in the Keyboard Properties dialog box. Refer to
"Keyboard Backlight" on page 104 for details about this option.
Note: Keep in mind that this option may be restricted to supervisory use only.

The Display
7545s are equipped with display backlighting to improve character visibility in low light
conditions. The backlight 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.

light will become active) and the intensity of the backlight can be specified in the Display
Properties dialog box in the Control Panel.
Note: Refer to "Backlight" on page 99 for details about the Display Properties dialog
box.
