Suspend Timeout
When NEO 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 hand-held CPU enters a sleep state, and the radio is shut
off. The state of the device (RAM contents) is preserved. Pressing [ENTER] wakes the
system from suspend state. When NEO is in suspend state, the network connection will not
be broken immediately. If the connection is dropped, you must re-establish the network
connection.
5.5.4.3 Suspend Threshold
The Suspend Threshold lets you determine when NEO will shut down. If the slider is left at
the default value, Maximum Operating Time , the hand-held 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 will shut 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 10 minutes. To
further reduce power consumption, carefully consider the duration of time
that the display and the keyboard backlight are ‘on’ (see “Display Back-
light” on page 78 and “Keyboard Backlight” on page 82).
