The major performance characteristics of the PhySys are: trouble-free emission of stimulation current and ultrasound, also
underpressure in connection with the vacuum unit with the set parameters, as well as trouble-free operation of all functions.
Guidelines and manufacturer's declaration – Electromagnetic immunity
The PhySys device is intended to be operated in the electromagnetic environment as indicated below. The customer or user
of the PhySys device should ensure that it is used in such an environment.

Portable and mobile radio equipment should not be
used at a distance away from the PhySys, including
the cables, that is less than the recommended
safety distance which is calculated according to the
equation applicable to the transmission frequency.
Recommended safety distance:
d= 1.17 √P
d= 0.35 √P for 80 MHz to 800 MHz
d= 0.7 √P for 800 MHz to 2.5 GHz
with P as the rated output of the transmitter in watts
(w) according to the information of the
manufacturer of the transmitter and d as the
recommended safety distance in meters (m).
At all frequencies, the field strength of stationary
radio transmitter should be less than the

In the environment of devices which bear the
following symbols, interferences are possible:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not be applicable in all cases. The propagation of electromagnetic variables is influenced by
absorption and reflection from buildings, objects and people.
