Portable and mobile RF communications equipment should be used no closer to any part
of the BC40 Wrist Digital Blood Pressure Monitor, including cables, than the recommen-
ded 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).b
Field strengths from fixed RF transmitters, as determined by an electromagnetic site
survey,a should be less than the compliance level in each frequency range.b
Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic is affected by absorption and reflection from structures,
objects and people.
