(15).
(The mode of operation,
applicator type and remaining treatment time are kept stored.)
e)
End of the adjusted treatment time. (The mode of operation and applicator type remain stored.
Cancel the acoustic signal by turning the dosage knob to the left.)

3.9
Switching off by the safety circuit
After switching on the therapy unit and during the operation the microcontroller, in charge of the
entire control functions of the unit, automatically performs many control sequences to ensure the
safety of patient and therapy unit. If any error is being detected it is shown on the “Dosage“
display
(15)
and the output power is immediately switched off. This error condition is
additionally indicated by an intermittent acoustic signal.
The error messages are indicated by the symbols:
FE 1, FE 2, FE 4, FE 5, FE 6, FE 7, FE 9, FE a, FE b, FEC.
If anyone of these error messages is displayed the therapy unit must be switched off and the after-
sales service informed.
The FE 0 message means the parameter settings are incomplete. This condition is to be
eliminated as described in subparagraph 2.7. No acoustic signal follows this error message.
