Recommended separation distances between portable and mobile RF com-
munications equipment and the EQUIPMENT or SYSTEM – for EQUIPMENT or
SYSTEM that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications equipment and the BM49 blood pressure monitor
The BM49 blood pressure monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the BM49 blood pressure monitor can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF commu-
nications equipment (transmitters) and the BM49 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 transmitter in watts (W) according to the transmitter manufac-
turer.
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.
