All products are designed and manufactured by the TellSystem and it's partners, thanks to the R&D laboratory which employee’s high calibre engineers. Projects are realised with state of the art instruments, such as the latest generation of emulators for microprocessor’s programming and computers such as CAD. Once the prototype has been built it will be subjected during its testing period to severe controls by our engineers assisted by using the sophisticated instruments in our laboratories.

All testing is performed in house, by using the needle bench created in our workshop. All work is monitored by computers systems created ad hoc for the specific product. Before the product goes into sale, it’s tested on electronic and functional level. Thanks to the stringent controls and the total quality methodology, that consist in controlling every single electronic board.
