2.6 - SETUP MENU 

This menu contains the parameters of certain special and configuration functions of the machine on which the 
control unit works. 

 

 

Keep in mind that only skilled personnel are permitted to edit the following parameters to 
prevent damage to people or equipment. 

 
In order to access this menu, press buttons 

 and 

 at the same time for about one second. Once inside the 

menu, the different parameters are shown in sequence.
