Solution
When all switches do not respond
When the same phenomenon occurs with all switches, try the solution for the next section T.3.1.3 Can the Display Unit enter offline mode?
When using the IPC Series, refer to the following.
T.3.3 Different part of the display responds when touched (switch), or responds by itself - When Using WinGP
Refer to the "SP5000 Series Open Box Reference Manual" when using the SP5000 Series Open Box. You can download the manual from our support site (http://www.pro-face.com/trans/en/manual/1001.html).

An interlock function may be set for the switches. Please check the settings.
