Powering a Terminal On and Off
A terminal must be connected to a main power supply (e.g., a vehicle battery). If you remove
this power supply, the terminal suspends and cannot be turned on again until you reconnect
the power. An internal battery maintains data while the terminal is suspended, but it cannot
be used to operate the terminal. Save all your data and close all applications before removing
a terminal’s main power supply. See page 2-8 for more information.
Powering On
To turn the terminal on, press the ON/OFF key located at the top right corner of the alpha
section of the keyboard. As the terminal starts, several screens of information appear,
followed by the application screen set to run at your facility. If the terminal does not power
on, see Chapter 6, Troubleshooting.

Suspending or Turning Off the Terminal
To suspend the terminal, press the ON/OFF key. The terminal appears to turn off. However
if you press the ON/OFF key again, the terminal resumes its previous session.
Forcing the Terminal into Suspend
If the terminal does not suspend when you press the ON/OFF key, you can force it into suspend.
To do this, press and hold the ON/OFF key for 15 seconds, or until the display goes dark.
Turning the Terminal Off
Normally, you will not turn the terminal off: you will place it into suspend. The terminal only
turns off if you have:
!
disconnected the power cable, AND
!
allowed the internal battery to run down.
For more information, see Installation and the Internal Battery on pa g e2-8.
To start the terminal press the ON/OFF key.
