Head Warming Feature
The Head Warming feature of an Vectra® Neo Clinical Therapy System utilizes
Ultrasound output, resulting in warming of the Applicator to increase patient
comfort.
With Head Warming enabled, ultrasound is emitted without pressing the Start
button while an ultrasound treatment is being set up. The Applicator LED will
not illuminate during the Head Warming period. US Channel will indicate
“Head Warming”.
