Recommended separation distances between portable and mobile RF
The bed is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the bed can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the 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 estimated using the equation applicable to the power 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 80MHz and 800MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected
NOTE 2
by absorption and reflection from structures, objects and people.
