The table below provides the recommended separation distances (in meters) between
portable and mobile RF communications equipment and the CARESCAPE Monitor
B850.
The CARESCAPE Monitor B850 is intended for use in the electromagnetic
environment on which radiated RF disturbances are controlled. The customer or the
user of the CARESCAPE Monitor B850 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the CARESCAPE Monitor B850 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.
