Portable and mobile RF communications equipment should be used no closer to any part of the Digital Blood
Pressure Monitor, including cables, than the recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2.5 GHz
Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation distance in metres (m).

than the compliance level in each frequency range.

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 Digital Blood Pressure Monitor is used exceeds the
applicable RF compliance level above, the Digital 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 Digital Blood Pressure Monitor.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3V/m.
NOTE 1
At 80 MHz and 800 MHz, 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.
