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.

Recommended separation distances between portable and mobile RF
communications equipment and EasyOne Pro/LAB
EasyOne Pro/LAB is intended for use in the electromagnetic environment in
which radiated RF disturbances are controlled. The user of EasyOne Pro/LAB
can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment
(transmitters) and EasyOne Pro/LAB as recommended below, according to the
maximum output power of the communication equipment.
