Recommended separation distances between portable and mobile RF communications equipment and the EQUIPMENT or SYS-
TEM – for EQUIPMENT or SYSTEM that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications equipment and the BC81 blood pressure
monitor
The BC81 blood pressure monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are con-
trolled. The customer or the user of the BC81 blood pressure monitor can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the BC81 blood pressure 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 metres (m) can be
estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the trans-
mitter 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.
