Display Properties
Important: To maximize battery run time, keep the display backlight bright-
ness and active durations as low as possible.
ON Threshold
The 7530 G2 is equipped with an ambient light sensor. This sliding bar allows you
to determine how dark the ambient light needs to be before the backlight turns on.
Intensity
This parameter is used to adjust the light intensity of the 7530 G2 backlight.
Sliding the bar to the left lowers the light intensity, and sliding it to the right raises
the intensity.
Bright For
The value chosen from this dropdown menu determines the duration of time that the
backlight stays on at the configured intensity after the last user action (keypress or
scan trigger).
Dim For
The value chosen from this dropdown menu determines the duration of time that
the backlight stays on at half the configured intensity (dimmed backlight) after
expiration of the Bright For delay and as long as no user action takes place (such as
a keypress or scan trigger). At the expiration of the Dim For duration, the display
backlight shuts off.
External Power Checkbox
When you select the checkbox next to When using external power keep the
backlight always ON, the backlight remains ON at the configured intensity when
the 7530 G2 is operating with external power (not battery power). If the 7530 G2 is
drawing power from its battery, this option is ignored and the other parameters
defined in Display Properties dialog box take affect.
