Recommended separation distances between portable and mobile RF
communications equipment and
EasyOne Air
EasyOne Air
is intended for use in the electromagnetic environment in which
radiated RF disturbances are controlled. The user of
EasyOne Air
can help
prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters)
and
EasyOne Air
as recommended below, according to the maximum output
power of the communication 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 frequency of the transmitter, where
P
is the maximum
output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
Note: An additional factor of 10/3 is used in calculating the recommended separation distance to decrease the
likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought
into patient areas.
