If you are going to use the touchscreen on the terminal, power up the terminal.
This screen will be displayed.
If the terminal has a physical touchscreen, it is supplied with a stylus intended
to be used with the screen.

Alternatively, and for terminals without a physical touchscreen, once the terminal is powered up, you can
access the terminal's ‘virtual’ touchscreen on a PC using the IRIS Toolbox software. For details on how to set
up the toolbox, see “Appendix 1: Setting up the IRIS Toolbox”.
