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 metres (m).
Fields 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 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.
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 BabyCO is used exceeds the applicable RF compliance level
above, the BabyCO should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-
orientating or relocating the BabyCO.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
Recommended separation distances between
portable and mobile RF communications equipment and the BabyCO
The BabyCO is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the BabyCO can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the BabyCO as
recommended below, according to the maximum output power of the communications
equipment.
