There is insufficient ultrasound coupling. Use gel or
lotion labeled for therapeutic ultrasound coupling.
Resume treatment after applying proper couplant.
Replace applicator.
The Sonicator Plus 992 cannot tune to the applicator
transducer. Turn unit off and then on and try to begin
another ultrasound treatment. If the error code
persists, the applicator and/or the Sonicator Plus 992
require servicing.
Replace cable.
Replace applicator.
There is a malfunction in the power output circuitry
for ultrasound. Turn unit off and then on and try to
begin another ultrasound treatment. If the error code
persists, the Sonicator Plus 992 requires servicing.
Replace main board.
There is a malfunction in the power output circuitry
for ultrasound. Turn unit off and then on and try to
begin another ultrasound treatment. If the error code
persists, the Sonicator Plus 992 requires servicing.
Replace main board.
There is an output voltage error for electrical
stimulation. If powering unit OFF and restarting does
not remove error, the unit requires servicing.
Replace electrode cables.
Replace main board.
If E7 occurs during the treatment the patient
connection impedance may be increasing because the
electrodes are drying out or lifting from the patient.
If E7 occurs when the output is first being adjusted, it
may mean the electrodes or cables are not making a
good circuit. Check cable and electrode connections
and make sure electrodes are making good contact
with the patient.
In the continuous treatment modes the output voltage
is reduced while the unit monitors the impedance of
the patient connection. If the unit is in amplitude
modulated modes, such as recip or surge, this patient
connection error causes the unit to go into the HOLD
mode.
All patient connection errors should be investigated to
determine their cause.
