Portable and mobile RF communications
equipment should be used no closer to
any part of the Infant Phototherapy
Equipment, including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance:
d = 1.2

where P is the maximum output power
rating of the transmitter (W) according
to the transmitter manufacturer and d is
the recommended separation distance

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 Infant Phototherapy Equipment is used exceeds the
applicable RF compliance level above, the Infant Phototherapy Equipment should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Infant Phototherapy Equipment.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
c
The ISM(industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765MHz to
6.795 MHz; 13.553MHz to 13.567MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
WARNING
Excessive ambient EM (Electromagnetic) DISTURBANCES can cause the pressure of the unit to
be temporarily excessively high or low. Please use in environments below the above test
standards.
