Section 6—Maintenance and
Troubleshooting
6.1 Cleaning the Sonicator 740 and its ultrasound applicator
1. The Sonicator 740 can be wiped off with a damp cloth. The power cord should be disconnected from the
unit before this is done. In the case of stubborn dirt a gentle household cleaner can be sprayed on the
cloth and then wiped on the unit. If this method is used, remove any cleaner residue with a damp cloth.
Do not spray cleaner into the vents of the unit.
2. Use soap and water for routine cleaning of the Sonicator 740 applicator. When disinfection is necessary,
wipe with a disinfectant such as a 10% bleach solution. Rinse the applicator thoroughly after
disinfection to remove any residue. The Sonicator 740 applicator
is neither autoclavable nor
gas
sterilizable.
6.2 Routine
Maintenance
1. To assure accurate performance of the Sonicator 740, calibration verification of ultrasonic output should
be performed on an annual basis.
2. Standard medical electrical safety checks should be performed annually by qualified biomedical
engineers or technicians trained to perform these procedures.
3. Inspect treatment head for cracks, since they may allow ingress of conductive fluid(s).
4. Inspect treatment head cables and associated connectors for damage.
5. Avoid rough handling of the treatment applicator, since it is critical to the safe and effective application
of therapeutic ultrasound and relatively fragile.
6.3 Troubleshooting the Sonicator 740
Symptom Action
1.
Nothing lights when
mains power switch is
turned on.
Is the battery installed? If it is, it may require charging. Plug unit into wall
outlet and turn on. If unit comes on observe battery icon to see if it charged.
If there is no battery installed verify that the line cord is connected to the
outlet? Is the line cord securely connected to the Sonicator 740? Is there
power to the outlet? Unit may require servicing if none of the above resolves
the problem.
2.
A continuous beep
occurs when the
battery is installed.
A button on the keypad has been pressed while the battery was installed. To
stop the alarm, remove the battery and reinstall it. Please note: turning the
unit on its side while installing the battery will keep the pressure off the
buttons.
3.
1
Check applicator cable connections to make sure they are securely attached
to the Sonicator 740 and the applicator and the locking rings are turned fully
clockwise to lock connectors.
4.
2
There is insufficient ultrasound coupling. Use gel or lotion labeled for
therapeutic ultrasound coupling. Resume treatment after applying proper
couplant. See number 13 in section 4 of this manual for additional
information on efficient coupling of ultrasound to the patient.
5.
3
The Sonicator 740 cannot tune to the applicator transducer. Try a different
applicator. Press “Stop” to clear error. If error does not repeat with the new
transducer, the old transducer needs servicing. If error repeats with the new
transducer, the unit needs servicing.
6.
4
There is a malfunction in the power output circuitry. The Sonicator 740
requires servicing.
