The electrical control panels of the machines supplied by us, allow a continuous telephone connection with the headquarters on customer request. Consequently, if required, it is possible to examine by remote control any problems that may occur to the system, and to give an immediate solution in most cases. The supply units have a two-year service guarantee. Faced with any need, the user can request free remote or direct intervention, being the simple cost of the transfer from the headquarters to the factory, and the costs of board and lodging.
