When the 7545 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 7545 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 7545 is in suspend state, the network connection will not be
broken immediately. If the connection is dropped, you must re-establish the network
connection.
