Table 206: Recommended safe distances
between portable and mobile HF communi-
cations equipment and wellsystem MED-
WAVE TOUCH
wellsystem MEDWAVE TOUCH has been designed for use in an electromag-
netic environment in which the radiated HF interference is controlled. The
operator of the massage device can help to reduce electromagnetic interfer-
ence by maintaining a safe distance between the portable and mobile HF
communication devices (transmitters) and the device itself as recommended
below with regard to the communication device's maximum output power.

The recommended safe distance (d) in metres (m) can be determined by
using the equation that applies to the transmitters frequency in the case of
transmitters where their nominal power is not listed above, whereby 'P' is the
nominal transmitter power in Watts (W) according to the details supplied by
the manufacturer of the transmitter.
Comment 1: The higher value applies to 80 MHz und 800 MHz.
Comment 2: The propagation of electromagnetic waves is affected by absorp-
tion and reflexes caused by buildings, objects and people.
7.1.5
Influence by elecromagnetic interference
If the essential performance features (see 5.1) are influenced by electromag-
netic interference or do not exist at all, there is no risk for the user.

Form for reporting incidents
The supplementary report form can be found in the Book of Medical Devices
(order no. 1020298-..).
