Head Temperature - Over Heating
If coupling (the eective degree to which the Ultrasound energy is delivered from the soundhead to the patient’s body) is not
adequate during treatment, the temperature of the soundhead rises and the patient does not receive the full intended dosage.
If the SOUNDHEAD reaches approximately 108 degrees, ULTRASOUND will be disabled and the Operations Screen will
read: “SOUNDHEAD IS TOO HOT! OUTPUT HAS BEEN DISABLED TO ALLOW COOLING.”
e soundhead must be cooled before the treatment can resume. When the soundhead cools suciently, press START
to resume the treatment. e output power resumes, the display returns to its normal state, and the timer resumes. e
soundhead should cool quickly if placed in the soundhead holder or if held exposed to the air. Larger soundheads take longer
to cool than smaller heads. If the soundhead is not cooling as quickly as needed to resume the treatment, it can be placed in
room temperature water to quicken the cooling process. Sometimes just applying more conductive gel will adequately cool
the head.
NEVER USE ICE OR ICE PACKS TO COOL THE SOUNDHEADS as this is likely to cause thermal shock to the electronic
components of the soundhead and may necessitate a costly repair. Heads damaged by thermal shock are not covered by the
warranty.
To prevent overheating of the soundhead, maintain good coupling throughout the treatment by applying ample conductive
gel or lotion. Reducing the power when treating an area where it is dicult to obtain good coupling will also keep the
soundhead from overheating.
