Affinity® Three Birthing Bed and Affinity® Four Birthing Bed User Manual
(USR025 REV 6)
Recommended separation distances between portable and mobile RF communications equipment and the
P3700 Affinity® Three Birthing Bed and Affinity® Four Birthing Bed
The P3700 Affinity® Three Birthing Bed and Affinity® Four Birthing Bed are intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the P3700 Affinity® Three Birthing Bed and Affinity® Four
Birthing Bed can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the P3700 Affinity® Three Birthing Bed and Affinity® Four Birthing Bed 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 metres (m) can be esti-
mated 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 struc-
tures, objects and people.
