Portable and mobile RF
communications equipment should be
used no closer to any part of the
Patient Monitor, including cables, than

manufacturer and d is the
recommended separation distance in
metres (m).
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 the
following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
