rF emissions
CIsPr 11
Group 1
The chair uses rF energy only for its internal
function. Therefore, its rF emissions are very low
and are not likely to cause any interference in
nearby electronic equipment.

Recommended separation distances
between portable and mobile Rf communications equipment and the chair
The chair is intended for use in the electromagnetic environment in which radiated rF disturbances
are controlled. the customer or the user of the table can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile rF communications equipment
(transmitters) and the chair as recommended below, according to the maximum output 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 maximum output 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.
