Recommended separation distances between portable and mobile RF communications
equipment and the Medical Digital Blood Pressure Monitor ORO-N4 CLASSIC
The “Digital Blood Pressure Monitor ORO-N4 CLASSIC” is intended for use in an
electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Medical Digital Blood Pressure Monitor ORO-N4
CLASSIC can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters)
and the “Digital Blood Pressure Monitor ORO-N4 CLASSIC ” 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.
