Recommended separation distance between
portable and mobile RF communications equipment and the pump for Cococia Fuka
The pump for Cococia F
ū
ka is intended for use in an electromagnetic environment (for home and
professional healthcare) in which radiated RF disturbances are controlled. The customer or the user
of the pump for Cococia F
ū
ka can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the pump for
Cococia F
ū
ka 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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
Field strengths from fixed transmitters, such as those of base stations for radio (cellular/cordless) telephones, land mobile
radios, amateur radios, AM and FM radio broadcasts, and TV broadcasts cannot be predicted theoretically with accuracy. To
determine the electromagnetic environment due to fixed RF transmitters, an electromagnetic survey of the site should be
considered. If the measured field strength in the location in which the air mattress is used exceeds the applicable RF
compliance level above, the air mattress should be observed to verify whether or not it is operating appropriately. Shall the
device be used within one mile distance from AM, FM, or TV broadcast antennas, it needs to be installed according to the
EMC information provided. If an abnormal operation is seen, take additional measures as needed, such as changing the
location of use of the pump for Cococia F
ū
ka.
