B. Head Warming Feature Specifications
The Head Warming feature of an Intelect 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 "Warming".

Refer to these specifications as necessary when
troubleshooting the Ultrasound PC Board and Applicators.
Do not apply the Ultrasound Applicator to the patient during the Head
Warming period. Applicator must remain in Applicator Hook during the
Head Warming period.
