Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur

radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagne-

tic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the

loc

ation in which the BC40 Wrist Digital Blood Pressure Monitor is used exceeds the applicable RF compliance level above, the BC40

Wrist Digital Blood Pressure Monitor should be observed to verify normal operation. If abnormal performance is observed, additional

measures may be necessary, such as re¬orienting or relocating the BC40 Wrist Digital Blood Pressure Monitor.

b

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.

Recommended separation distances between portable and mobile RF communications equipment and the BC40 Wrist Digital Blood Pressure Monitor

The BC40 Wrist Digital 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 BC40 Wrist Digital Blood Pressure Monitor can help prevent electromagnetic interference by main-

taining a minimum distance between portable and mobile RF communications equipment (transmitters) and the BC40 Wrist Digital Blood Pres-

sure 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 aected by absorption and reflection from structures,
