Valleylab Force Fx Features

The Covidien Valleylab Force FX is a digital electrosurgical unit. The Force FXc is a high power digital electrosurgical unit. Both generators feature computer controlled Instant Response Technology designed to ensure a consistent clinical effect through all tissue types. You can use handset or footswitch controls to activate the generator. Receptacles are marked to ensure the correct connection of accessories. Indicators alert you when the generator is activated. The Force FX™ allows you to adjust the activation tone volume and reset the mode and power settings used previously. The Force FX™ can be used in conjunction with the Valleylab Force GSU System and the Valleylab Electroshield Monitor. Refer to the manuals provided with these products for more information.
