AGFA 5367/300, User Manual

Page: 133 / 168

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 manu-
facturer information on the transmitter, only for transmitters where the rat-
ed 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 re-
flections from buildings, objects and people.

• Immunity to RF wireless communication equipment
• Precautions on EMC
