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