The backlight is activated for a configurable amount of time if the ambient light is below a specified threshold and if the 7535 is in use (key press, scanner trigger or data received from the host). The
Display Properties
dialogue box in the

allows you to specify the intensity of the backlight along with how the backlight behaves in low-light conditions and when the unit is not in use.
