Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The Affinity® Three Birthing Bed and Affinity® Four Birthing Bed are intended for use in the electromagnetic environment speci-
fied below. The customer or the user of the Affinity® Three Birthing Bed and Affinity® Four Birthing Bed should make sure they
are used in such an environment.

Portable and mobile RF communications equipment should be used no
closer to any part of the P3700, including cables, than the recommended
separation distance calculated from the equation applicable to the fre-
quency of the transmitter.
Recommended separation distance
Where P is the maximum output power rating of the transmitter in watts
(W) according to the transmitter manufacturer and d is the recom-
mended separation in metres (m).

Interference may occur in the vicinity of equipment marked with this
symbol.
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 Affinity® Three Birthing Bed and Affinity® Four
Birthing Bed are used exceeds the applicable RF compliance level above, the Affinity® Three Birthing Bed and Affinity® Four Birthing Bed should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
Affinity® Three Birthing Bed and Affinity® Four Birthing Bed.
b. Over the frequency range of 150 kHz to 80 MHz, field strength should be less than 3 V/m.
Note 1: At 80 MHZ and 800 MHz, the higher the 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.
