7 What to do when problems occur
We have found that most problems occur because of inadvertent operating errors. Therefore, when
the Auto*Therm 395 displays an error code, please check whether the operating instructions have
been correctly followed (sections 5 and 6).
If displays (14) and (15) and the light in the power switch (1) do not light when the unit is turned on,
check whether the unit is correctly connected to an active wall outlet and the power cord is connected
to the unit. Then check the fuses at the mains voltage connection to the unit
(33) . Remove the power
cord and lift the latch to remove the drawer containing the fuses (33) . Check the fuses and replace
one or more of them, if necessary. When you are done, reinsert the fuse drawer until the latch closes.
ATTENTION:
Replace fuses with ones of the same rating and type. lf the fuses blow frequently, please contact
service.
lf the error message “FE“ appears in the Intensity display (15) while turning the intensity knob (17)
clockwise check whether all parameters (mode of operation, applicator, time) are set.
lf display (16) shows only little or no coupling during the automatic tuning process indicated by “A” in
the time display (14) check whether the applicator(s) used correspond(s) to those chosen indicated by
the illuminated “APPLICATOR” button. i.e., insure that the correct applications are chosen.
Furthermore, check whether the applicator cable is connected firmly to the unit and to the applicator.
The treatment area should be larger than or the same size as the applicator surface.
The unit beeps if it is incorrectly adjusted. To assure safe operation of the Auto*Therm 395 and, thus
the safety of the patient, a number of control measures have been programmed into the unit, which
cause the power output to stop and an error code to be displayed (see section 5.9 for a complete list
of possible error codes).
