The BPM63ZB Arm Type Blood Pressure Monitor is intended for use in the electromagnetic
environment specified below. The customer or the user of the BPM63ZB Arm Type Blood Pressure
Monitor should assure that it is used in such an environment.

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 BPM63ZB Arm Type Blood Pressure Monitor is used
exceeds the applicable RF compliance level above, the BPM63ZB Arm 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 BPM63ZB Arm
Type Blood Pressure Monitor.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Portable and mobile RF communications equipment
should be used no closer to any part of the BPM63ZB
Arm 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.
