Recommended separation distances
Recommended separation distances between portable and mobile RF communications equipment and the EQUIPMENT
or SYSTEM – for EQUIPMENT or SYSTEM that are not LIFESUPPORTING
Recommended separation distances between portable and mobile RF communications equipment and the Blood pressure monitor
(BM 54).
The Blood pressure monitor (BM 54) is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Blood pressure monitor (BM 54) can help prevent electromagnetic interference by maintai-
ning a minimum distance between portable and mobile RF communications equipment (transmitters) and the Blood pressure monitor
(BM 54) 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 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.
