Electromagnetic Compatibility Information
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 BM52 blood
pressure monitor
The BM52 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 BM52 blood pressure monitor can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the BM52
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 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.
