SYSTEMS
ULTRASOUND SPECIFICATIONS
This section provides the necessary ultrasound specifications to aid in troubleshooting.
Refer to these specifications as necessary when troubleshooting the ultrasound PC Board and Applicators.
B. Head Warming Feature Specifications
The Head Warming feature of an Intelect
Transport/Vectra Genisys Ultrasound 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. The
Applicator LED will not illuminate during the
Head Warming period. Display will indicate
