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.

Portable and mobile RF communications equipment should be used no closer to any part of the
BW-210

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:
b
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.
