energy for the purpose of its operation. Therefore, other equipment may cause interference, even if that
other equipment complies with CISPR emission requirements.
In the following table, 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 metres
(m). The values given in brackets are for respiration.
Portable and mobile RF communications equipment should be used no closer to any part of the
monitor, including cables, than the recommended separation distance calculated from the equation
appropriate for the frequency of the transmitter.
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be
less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with this symbol:
