Consult the therapy manual "Pulsed short wave
therapy with the Curapuls 670", the chapter on 'Con-
tra-Indications'.
Combination therapy
Since the Curapuls 670 radiates a high-frequency field
that can affect electronic circuits inside nearby equip-
ment, you are strongly advised against any sort of
combination treatment using a second (electro medi-
cal) apparatus.
High-frequency interference
The Curapuls 670 complies with the present CE-de-
mands regarding HF-emission and immunity.
The Curapuls 670 produces an high-frequency field
that is designed to generate thermal and biological
effects in tissues and joints of the human body. In
free air, the strength of this high-frequency field gen-
erated from the electrodes, cables and treated pa-
tient is reduced quadratically with the distance. This
high-frequency field can affect electronic circuits of
equipment positioned in the vicinity.
This high-frequency interference is in almost all cases
the cause of so-called direct radiation on the statu-
tory permitted frequency of 27.12 MHz. Despite the
fact that the affected equipment is not tuned to this
frequency, detection appears in several circuits due
to the strong radiation, causing the modulation of
the high-frequency wave to become audible and/or
visible (through the neon checklight). With low- and
medium-frequency physiotherapy equipment this
modulation might become perceptible to the pa-
tient as well.
The susceptibility to high-frequency interference of
equipment from various manufacturers can be very dif-
ferent. This is due to the fact that some manufacturers
are still shielding their equipment insufficiently against
external high-frequency fields. Should interference arise,
we advise consulting the manufacturer concerned.
We recommend paying attention to the following
items in order to minimize the chance of high-fre-
quency interference.
• The larger the distance between the shortwave
unit and other equipment, the smaller the chance
of high-frequency interference. Place your
shortwave unit, including the patient under
treatment, at least 2 metres from surrounding
equipment and/or oblong metal objects.
• Use a separate mains group (phase) for the
shortwave apparatus. Keep mains leads wide
apart.

• Take care that the mains lead of the shortwave
apparatus does not come into the vicinity of the
patient and/or electrode leads, or of mains leads
from other (electro-medical) equipment.
• Use only a completely metal-free treatment chair
or couch.
