The table below provides the recommended separation distances (in meters)
between portable and mobile RF communication equipment and the MAC 3500
system.
The MAC 3500 system is intended for use in the electromagnetic environment on
which radiated RF disturbances are controlled. The customer or the user of the MAC
3500 system can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the MAC 3500 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 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
