Recommended separation distance between portable and mobile RF
communications equipment and the FORA TN'G BP Blood Pressure Monitoring
The FORA TN'G BP Blood Pressure Monitoring System is intended for use in an
electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the FORA TN'G BP Blood Pressure Monitoring System
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
FORA TN'G BP Blood Pressure Monitoring 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 be 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 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency
range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects and people.
