Cerebus Instructions for Use
27
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.
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 Table 206).

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 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.
