5.6.5.2 Keyboard Backlight

• In the Keyboard Properties dialog box, open the Backlight tab.
ON Threshold
The ON Threshold sliding bar allows you to determine how dark the ambient light needs to
be before the keyboard backlight turns on.
Intensity
This parameter is used to adjust the light intensity of the 7545 keyboard backlight. Sliding
the bar to the left darkens the keyboard backlight intensity, and sliding it to the right lightens
the intensity.
Note: The keypad backlight maximum brightness will decrease over time as it ages. Use
mid-range intensity settings when possible to extend the backlight lifespan. When
the backlight starts to dim, use this parameter to make it brighter.
ON For
The value chosen from this drop-down menu determines the duration of time that the key-
board backlight stays on after the last user action (keypress or scan trigger).
Note: Tapping in the checkbox next to 'When using external power, keep the backlight
always ON' forces the keypad backlight to remain on when the unit is operating
with external power.
