“HOT” Error: During an Ultrasound treatment, if the
soundhead becomes too hot, the “HOT” error message
is displayed and the treatment is paused until the
soundhead is cooled.
Note: Pressing the Time UP or DOWN ARROW keys will return the display from
bar graph to the treatment time display. However, pressing these keys will change
the treatment time as well.
Head Temperature Hot
If the temperature reaches the
maximum level allowed, the treatment
is automatically PAUSED, the output
power is stopped, the treatment time
stops counting down, and the POWER
INTENSITY display shows the error
message “HOT”. When this condition
occurs, the soundhead must be cooled
down before the treatment can resume
Once the soundhead is cooled, press
PAUSE or START to resume the
treatment. If the soundhead is still too hot, the device will not allow you to continue.
The soundhead will cool slowly if placed in the soundhead holder or if held exposed
to the air. Larger soundheads take longer to cool than smaller heads. To resume the
treatment right away, you can place the soundhead in cool/room temperature water to
cool the head more quickly.
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. 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.
No Soundhead
If the device cannot detect a soundhead
during setup or delivery of an Ultrasound
treatment, the error message “HEAD” is
displayed in the TIME DISPLAY. A
number from 0 - 3 will simultaneously
appear in the POWER DISPLAY window.
If this error occurs, check to be sure the
soundhead is firmly plugged into its
connector. If you are unable to clear the
message by reconnecting the soundhead,
contact Dynatronics’ customer service department for assistance.
