Portable and mobile RF communications
equipment should not be used closer to
any part of the medical device, including
cables, than the recommended distances
calculated from 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
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic
survey a, should be less than the
compliance level in each frequency range.
Interference may occur in the vicinity of
equipment marked with the following
symbol:
Recommended separation distances between portable and mobile communication equipment and the
medical device
The medical device is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the medical device can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communication equipment (transmitters) and
the medical device as recommended below, according to the maximum output power of the communications
equipment.
