There are several ways that the mobile terminal can go into Suspend mode from the Power ON state:
•
Power Button:
The mobile terminal will go into Suspend mode if the operator presses the Power
button for less than 1 sec while the unit is in the fully Power ON state. If the Power button is
pressed for more than 1 sec, the unit will perform a normal Power Off sequence.
•
Touchscreen
: The touchscreen interface can be used to command the mobile terminal to go to
Suspend mode via the Start/Suspend command.
•
Automatic Power Management:
The mobile terminal can be configured to go to Suspend mode
automatically (see section 5.3) if the touchscreen or function buttons have not been used for some
(user configurable) amount of time.
