RECOMMENDED SEPARATION DISTANCES
FOR COMMUNICATIONS EQUIPMENT
The infusion system is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The recommendations provided in
Table A-4
help
the user of the infusion system to prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment
(transmitters) and the infuser, according to the maximum output power
of the communications equipment.
Note: These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structure, objects and people.
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
The ISM bands between 150 kHz and 80 MHz are 6.765 MHz to 6.695 MHz; 13.553 MHz
to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.660 MHz to 40.700 MHz.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d in meters (m) can be determined 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.
