Recommended separation distances between portable and mobile RF communications 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

BM45

blood pressure monitor

The BM45 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 BM45 blood pressure monitor can help prevent electromagnetic interference by maintaining a minimum distance

between portable and mobile RF communications equipment (transmitters) and the BM45 blood pressure monitor as recommended below,

according to the maximum output power of the communications equipment.

0.1 0.370 0.370 0.740

1 1.170 1.170 2.340

10 3.700 3.700 7.400

100 11.7 11.7 23.4

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 aected by absorption and reﬂection from struc

tures, objects and people.
