Troubleshooting
Experience has shown that the most problems by far occur because of inadvertent operating
errors. Therefore, before suspecting a fault in the therapy unit, please, check whether the present
operating instructions have been correctly followed (cf. paragraphs 2 and 3).
When after switching on the therapy unit the displays
(14)
and
(15)
and the indicator lamp in
power switch
(1)
do not light, check whether the therapy unit is correctly connected to the mains
socket outlet and the last one is alive. If so, check the fuses at the mains voltage connection of
the therapy unit
(44).
To do this, lift the latch and take the „drawer“ with the fuses out of the
mains voltage connector
(44).
After checking and, if required, replacing a fuse re-insert until the
latch catches.
ATTENTION:
Fuses shall only be replaced by ones of the same rating and type. If fuses blow
more frequently, please, contact our after-sales service.
If the error message
„FE 0“
appears on the „Dosage“ display
(15)
when turning the dosage knob
(17)
to the right check whether all parameters (mode of operation, applicator, time) were chosen
or not. If display
(16)
shows only little or no coupling during the automatic tuning process
indicated by
“Ab“
on display
(14)
check whether the applicator(s) used correspond(s) to that
chosen by the actuated
„APPLICATOR“
button(s).
Furthermore, check whether the applicator cable connection and the applicator positions are
correct. The area to be treated should be larger than or at least as large as the applicator surface.
Incorrect adjustment at the therapy unit during the treatment is acoustically signalled. For safe
operation of the therapy unit and, thus the safety of the patient, a number of control measures
were programmed which in case of error result in switching off the output power and displaying
the type of error (cf. subparagraph 2.9).
