This dropdown menu allows you to specify whether the unit is using AC Power or
Battery Power.
Switch State To Suspend
Important: Psion Teklogix recommends setting the Suspend value to 10 min-
utes. Setting ‘Switch State To Suspend’ to ‘Never’ will adversely
affect the battery run time.
To further reduce power consumption, carefully consider the
duration of time that the display backlight is ‘on’ (see “Display
Backlight” on page 89).
When the 7535 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
Switch State To Suspend field to determine when
the unit will go to sleep (appear to be off).
When the time in the
Suspend field elapses without any activity, the unit enters Suspend
state. In
Suspend state, the 7535 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 the 7535 is in suspend state, the network
connection will not be broken immediately. If the connection is dropped, you must
re-establish the network connection.
