EFERENCE MANUAL
This device is intended for operation in an electromagnetic
environment in which the radiated high frequency disturbance
variables are monitored. The user of the device can help to
prevent electromagnetic disruptions by maintaining the
minimum distances between portable and mobile high frequency
communication equipment (transmitters) and the device as
recommended below, in accordance with the maximum output
power of the communications equipment.

The distance can be determined through the equation for each respective column.
P is the rated power of the transmitter in watts (W) according to the manufacturer information on
the transmitter, only for transmitters where the rated power is not mentioned in the above table.
• REMARK 1 : An additional factor of 10/3 has been used to calculate the recommended protective
distance of transmitters in the frequency range from 80 MHz to 2.5 GHz, to reduce the probability
that mobile portable communication equipment unintentionally brought into the area of the
patients will lead to a disruption.
• REMARK 2 : These Guidelines may not be relevant in all situations. The dispersion of
electromagnetic waves is influenced by absorption and reflections from buildings, objects and
people.
