Head Warming Feature
The Head Warming feature of an Vectra Genisys Combination
Therapy System utilizes Ultrasound output resulting in warming
of the Sound Head to increase patient comfort.
With Head Warming enabled, ultrasound is emitted without
pressing the Start button. The Applicator LED will not illuminate
during the Head Warming period. US Channel will indicate "Head
Warming".
