a
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 electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered.
If the measured field strength in the location in which the Wrist Blood Pressure Monitor is used exceeds the applicable RF
compliance level above, the Wrist Blood Pressure Monitor should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the Wrist Blood Pressure
Monitor.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
