Problem Solving
The following are problems that could occur with the Dynatron 150plus. Appropriate
actions are also provided.
Soundhead Temperature Too Hot
If coupling (the effective degree at which the Ultrasound is delivered from the
soundhead to the patient’s body) is not adequate during treatment, the temperature of
the soundhead rises (see also “Head Temperature Hot,” page 12). The Dynatron
150plus uses several methods to inform the user of the temperature status throughout
the treatment:
• If the soundhead approaches maximum temperature, the power display begins
flashing to notify the user to improve coupling or reduce the power to prevent
the soundhead from becoming too hot.
• If the soundhead reaches maximum temperature the treatment is paused; the
output is stopped, the timer is paused, and the Pause light is lighted. When
the soundhead cools sufficiently, the power display and the lights on the
soundhead will cease flashing. You can then press PAUSE or START to
resume the treatment.
Cooling the Soundhead
The temperature alert not only ensures good coupling throughout the treatment, it
helps avoid damage to the soundhead crystal. If the soundhead becomes too hot, it
must be allowed to cool down before resuming the treatment. The head will cool
slowly if allowed to sit at room temperature. To cool the soundhead quickly, you can
place it in room temperature water. Sometimes just applying more conductive gel
will adequately cool the head. Larger soundheads will take longer to cool down.
DO NOT USE ICE to cool the soundhead as this can cause thermal shock to the
crystal and may necessitate a costly repair. Damage caused by thermal shock is
not covered under the warranty.
Whirlpool Treatments
If you are treating in a whirlpool, you may find the temperature reaches a high
enough temperature to cause the display to flash “105˚” (see also, Head Temperature
Bar Graph, page 11). This is a warning only to let you know you are approaching the
temperature limit. You may, however, continue with the treatment at this level. If
