AGFA CR 25.0 User Manual page 78

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.
