Table 206 – Recommended separation distances between portable and mobile RF communications equipment
and the EQUIPMENT or SYSTEM - for EQUIPMENT or SYSTEMS that are not LIFE-SUPPORTING (refer to
60601-1-2).
Recommended separation distances between portable and mobile RF communications equipment and
the Cerebus® system
The Cerebus® system is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the Cerebus® system can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the Cerebus® system 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 frequency 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 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.
