Recommended separation distances between portable and mobile RF
communications equipment and the device
The device is intended for use in an electromagnetic environment in which
radiated therefore disturbances are controlled. The customer or the user of the
device can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the device as recommended below, according to
the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in metres (m) can be estimated using the
equation applicable to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE1 To calculate the recommended separation distance of transmitters in
the frequency range of 80 MHz and 800 MHz to 2.5 GHz, an additional factor
of 10/3 has been used in order to reduce the probability of a mobile/portable
communications device unintentionally introduced into the patient area causing
a fault.
NOTE2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
