2.4.1 Power key
The P key turns the control box on and off.
To turn on the control box and the system, press P. After a brief pause, an
opening screen appears.
Note – If the system reports that there are upgrade files or other system files on the
control box, or that the operating system is out of date, contact your site supervisor
immediately.
To turn off the control box and the system, press and hold P for two to three
seconds until the control box shuts down. (This delay reduces the risk of you turning
off the power accidentally.) You can turn off the system from any screen or dialog.
2.4.2 System memory and the USB flash drive
Files and data are stored on the control box in an area known as system memory.
The files and data in system memory are used by the system and there is only
limited site supervisor access via the control box.
