Psion Omnii Hand-Held Computer User Manual
Intensity
This parameter is used to adjust the light intensity of the Omnii 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 drop-down menu determines the duration of time that the backlight stays on at
the configured intensity after the last user action (keypress, scan trigger).
Dim For
The value chosen from this drop-down 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 Check Box
When you select the check box next to When using external power keep the backlight always ON , the back-
light remains ON at the configured intensity when the Omnii is operating with external power (not battery
power). If the Omnii is drawing power from its battery, this option is ignored and the other parameters
defined in
Display Properties dialog box take effect.
Note: Backlight changes take effect immediately. You do not need to reset the unit.
To maximize battery run time, keep the display backlight brightness and active durations as
low as possible.
