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 strength in the location in which the mattress is used exceeds
the applicable RF compliance level above, the mattress should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating
the mattress.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3V/m.

Guidelines
Portable and mobile RF
communications
equipment should be
used no closer to any part
of the mattress, including
cables, than the
recommended separation
distance calculated from
the equation applicable to
the frequency of the
transmitter.
Recommended

Where P is the maximum
output power rating of the
transmitter in watts (W)
according to the
transmitter manufacturer
and d is the
recommended separation

Field strengths from fixed
RF transmitters, as
determined by an
electromagnetic site
a
survey , should be less
