The following table provides the recommended separation distances (in
meters) between portable and mobile RF communication equipment and
the MAC 600 system. The MAC 600 system is intended for use in the
electromagnetic environment on which radiated RF disturbances are
controlled. The customer or the user of the MAC 600 system can help
prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment
(transmitters) and the MAC 600 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 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
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
