Head Temperature Bar Graph; Display Watts Or W/Cm2 - Dynatronics Dynatron 850 Plus Service Manual

When the temperature is again satisfactory, press the START key to resume the treatment;
output power resumes, the displays return to its normal state, and the timer resumes. While the
soundhead is still too hot, the device will not allow you to resume the treatment.
To prevent overheating of the soundhead, maintain good coupling throughout the treatment.
For direct coupling, you may need to apply more conductive gel or lotion during the
treatment to achieve better coupling.
You can reduce the power during the treatment if you are treating an area where it is difficult
to obtain good coupling.

Head Temperature Bar Graph

During an ultrasound treatment, you can view a graph showing the relative soundhead
temperature by pressing SOUND and the HI/LO keys simultaneously. As shown in the
illustration below, the Time display shows the letter "H" followed by a bar graph with from 1
to 6 segments lighted. The more segments displayed, the hotter the soundhead. This display
does not provide an actual temperature reading, but does give a visual indication when the
soundhead is becoming too hot. To return to the treatment time display, press the TIME key.
