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