SantaMedical BW-210 Instruction Manual page 21

The BW-210 Wrist Type Blood Pressure Monitor is intended for use in the electromagnetic environment specified below. The customer or the
user of the BW-210 Wrist Type Blood Pressure Monitor should assure that it is used in such an environment.
Immunity test IEC 60601 Compliance
test level
Radiated RF 3 V/m
80 MHz to
IEC 61000-
4-3 2,5 GHz
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.
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 BW-210 Wrist Type Blood Pressure Monitor is used exceeds the applicable RF compliance level
above, the BW-210 Wrist Type 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 BW-210 Wrist Type Blood Pressure Monitor.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Guidance and manufacturer's declaration-electromagnetic immunity
level
3 V/m
Portable and mobile RF communications equipment should be used no closer to any part of the BW-210
Wrist Type Blood Pressure Monitor, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance
d=1.2 √P
d=1.2 √P
80 MHz to 800 MHZ
d=2.3 √P
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).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site surveyª, should be
less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
