Dynatron® 850plus & 550plus
General & Technical Information
116
• All intensity levels are automatically set to zero at the end of treatment (ensures proper
setting of intensity levels for the next patient).
• Internal surge protection protects against line noise, machine switching operation and any
other type of interference that could cause patient discomfort.
• Soundhead temperature monitoring prevents the soundhead from becoming too hot, both
to protect the soundhead crystal from damage and to ensure patient comfort.
Care and Cleaning Instructions
• Clean the outer surface of the Dynatron 850plus or 550plus with a slightly damp or
lightly moistened cloth. Mild household cleaners work well. Do not spray the solution
directly on the unit. First moisten the cloth and then wipe the unit off. Solvents, caustic
solutions and harsh or abrasive cleaners must never be used.
• Avoid stretching cords to full length, bending cords sharply or wrapping cords tightly.
Undue stress on cords can damage connections.
• Keep all food and soft drinks away from the machine and its accessories; spills can cause
costly damage to the machine and repairs for this type of damage are not covered by the
warranty.
• Do not drop the unit or the soundheads as severe damage will occur.
• Ultrasound heads should be cleaned with warm water. Always keep the head free from
gel buildup.
• 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.
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.
