NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflected
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 Babybed is used exceeds the applicable RF compliance level above, the Babybed should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the Babybed.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the
Babybed
The Babybed is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the Babybed can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the Babybed as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in meters
(m) can be estimated 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.
Note 1:
At 80 MHz and 800 MHz, the separation distance for 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.
