recommended separation distances between portable
and mobile rf communications equipment and the
blood pressure monitor
The blood pressure monitor is intended for use in an electro-
magnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the blood pressure
monitor can help prevent electromagnetic interference
by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters)
and the blood pressure monitor as recommended below,
according to the maximum output power of the communica-
tions 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.
