Ultrasound Head
• Ultrasound heads should be cleaned with warm water. Always keep the head free from gel buildup. Alcohol may be
used to sterilize the soundhead.
• Do not use ice water for cooling soundheads. Do not allow soundheads to overheat repeatedly. This could result in
thermal shock to the crystal. Damage of this type is not covered by the warranty.
• Do not drop the unit, probe, or the soundheads as severe damage will occur.
Suggested Maintenance Schedule
Service To Be Performed By A Technician:
Every 6 Months
• Test leads and carbon electrodes. Lead resistance should be less than 10% above the mean cable resistance.
Greater values indicate strand breakage and lead should be replaced.
Annually
• Annual Ultrasound calibration should be performed by a qualified technician.
• Check the output voltages and currents on all outputs.
• Inspect soundhead connectors on unit and on soundhead.
• Verify DAC calibration and current limits.
• It is recommended that the 25 Series device be sent to the manufacturer for annual calibration.
Maintenance Performed By User:
1. Inspect accessories daily for wear and damage. Examine cables and connectors on the cables for any visible sign of
wear or damage. Replace accessories as needed:
• Replace lead wires and carbon electrodes at least every six months.
• Replace self-adhesive electrodes after not more than 15 uses.
2. Examine Ultrasound heads periodically for cracks which may allow ingress of conductive fluid.
3. If a machine or soundhead is dropped, or if it sustains damage due to lightning, severe power surge, submersion
in water, or other incident that could cause damage to electronic components, the device must be examined by a
Dynatronics technician before being returned to clinical use.
4. For older devices contact Dynatronics or your Dynatronics dealer for information and pricing for current upgrades
to your device. Even if the machine is functioning properly, you can send it to Dynatronics for preventative
maintenance service for a nominal charge; call for pricing.
