above, the monitor should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the monitor.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
portable and mobile RF communications equipment and the Wireless Blood Pressure Wrist
The Wireless Blood Pressure Wrist Monitor is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the Wireless Blood
Pressure Wrist Monitor can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the monitor
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 determined 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.
