Recommended Separation Distances
This section describes recommended separation distances between portable and mobile RF
communications equipment and the Cardiac Stress Treadmill.
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to
2.5 GHz
3 V/m
80 MHz to 800 MHz:
800 MHz to 2.5 GHz:
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 site survey,
a
should be less than the
compliance level in each
frequency range.
b
Interference
may occur in the vicinity of
equipment marked with the
following symbol:
Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note:
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects and
people.
Note: Tests were verified with shielded input/output cables only.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in
the location in which the ST/TM55 or ST/TM65 is used exceeds the applicable RF
compliance level above, then the ST/TM55 or ST/TM65 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the ST/TM55 or ST/TM65.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
