Electrically Operated General Ward Bed
Operation and Maintenance Manual
(154588 REV 1)
Recommended separation distances between portable and mobile RF
communications equipment and the bed
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 meters (m)
can be estimated when you use the equation applicable to the frequency of the transmitter, where P is the maximum out-
put 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 structures, objects and people.
