Recommended Separation Distances - GE Dash 3000 Service Manual

Recommended separation distances

A-6
Electromagnetic compatibility (EMC): Electromagnetic compatibility (EMC)
The table below provides the recommended separation distances (in
meters) between portable and mobile RF communications equipment and
the Dash 3000/4000/5000.
The Dash 3000/4000/5000 is intended for use in the electromagnetic
environment on which radiated RF disturbances are controlled. The
customer or the user of the Dash 3000/4000/5000 can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment
(transmitters) and the Dash 3000/4000/5000 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 equitation 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 instances. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
