site of the device exceeds the compliance levels listed above, the device should
be monitored for proper function. If unusual performance characteristics are ob-
served, additional measures may be required such as changing orientation or the
location of the device.

The field strength should be less than 3 V/m for the frequency range of 150 kHz
to 80 MHz.

Recommended Safety Distances Between Portable and Mobile
HF Telecommunications Devices and the PNEUMO SURE High
Flow Insufflator
Recommended safety distances between portable and mobile HF telecommu-
nications devices and the insufflator
The PNEUMO SURE High Flow Insufflator is intended for use in an electromag-
netic environment where HF interferences are controlled. The user/operator of
the insufflator can contribute to lowering electromagnetic emissions by com-
plying with the minimum distance between portable and mobile HF telecom-
munications devices (transmitters) and the insufflator - depending on the
output power of the communication device listed below.

The safety distance d in meters [m] for transmitters with a max. rated output not
listed in the table above can be calculated by applying the corresponding formula
in the respective column. P is the max. rated output of the transmitter in watts
[W] according to the information provided by the manufacturer of the transmit-
ter.
Note 1: The higher frequency range applies for 80 and 800 MHz.
Note 2: These guidelines are probably not realizable in all cases. The distribution
and spread of electromagnetic quantities differs depending on the absorption
and reflection of buildings, objects, and people.
