Psion Teklogix Omnii Hand-Held Computer User Manual 117
Power Source
This drop-down menu allows you to specify whether the unit is using AC Power or
Battery Power.
Suspend Timeout
When Omnii is idle—not receiving any user input (a key touch, a scan, and so on) or system
activity (serial data, an activity initiated by an application, and so on)—the hand-held uses
the value assigned in the Suspend Timeout field to determine when the unit will go to sleep
(appear to be off).
When the time in the Suspend Timeout field elapses without any activity, the unit enters
suspend state. In suspend state, the Omnii CPU enters a sleep state, and wireless communi-
cation is shut off. The state of the device (RAM contents) is preserved. Pressing [ENTER]
wakes the system from suspend state.
5.5.8.3 Suspend Threshold and Estimated Battery Backup
The Suspend Threshold adjustment tells the system when to shut down when the battery
drains. If you choose Maximum Operating Time, the unit will run until the battery is com-
pletely empty; the RAM is only backed up for a short period of time. If you choose
Maximum Backup Time, the hand-held shuts off with more energy left in the battery so
RAM can be backed up for a longer period of time.
Important: Psion Teklogix recommends setting the Suspend value to 3 minutes. To
further reduce power consumption, carefully consider the duration of time
that the display backlight is ‘on’ (see “Backlight” on page 97).
