The field strength of stationary transmitters such as base stations of wireless
phones and cell phones, ham radio operators, AM and FM radio and TV stations
can theoretically not always determined in advance. A study of the installation
site should be considered to determine the electromagnetic environment con-
cerning the stationary transmitter. If the measured field strength at the pro-
posed FLOSTEADY Arthroscopy Pump installation and FLOSTEADY Arthroscopy
Pump operation site exceeds the concordance levels listed above, the FLOSTEADY
Arthroscopy Pump should be monitored to document proper functionality and
operation as intended. If unusual performance characteristics are observed, ad-
ditional measures may be required such as changing orientation or the location
of the device FLOSTEADY Arthroscopy Pump.

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 Telecommu-
nications Devices and the FLOSTEADY Arthroscopy Pump
The FLOSTEADY Arthroscopy Pump is intended for use in an electromagnetic
environment where HF interferences are controlled. The user/operator of the
FLOSTEADY Arthroscopy Pump can contribute to lowering electromagnetic
emissions by complying with the minimum distance between portable and
mobile HF telecommunications devices (transmitters) and the FLOSTEADY
Arthroscopy Pump - 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.
