The e-sphyg 3 Digital Blood Pressure Monitor is intended for use in the electromagnetic environment specified below. The
customer or the user of the e-sphyg 3 Digital Blood Pressure Monitor should assure that it is used in such an environment.
Compliance
Level
Portable and mobile RF communications equipment
should be used no closer to any part of the e-sphyg 3
Digital Blood Pressure Monitor, including cables, than
the recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.

d [3.5] P V 1
d [3.5] P 80 MHz to 800 MHz E1

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

The e-sphyg 3 Digital Blood Pressure Monitor is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the e-sphyg 3 Digital Blood Pressure Monitor can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the e-sphyg 3 Digital Blood Pressure Monitor as recommended below, according to the maximum
output power of the communications equipment
80 MHz to
800 MHz
800 MHz to
2.5GHz
For transmitters rated at a maximum output power not listed above the recommended separation distance d in metres (m) can be
estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1:
At 80 MHz and 800 MHz, the separation distance for 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.
NOTE 1:
At 80 MHz and 800 MHz, the higher frequency range applies.

These guidelines may not apply in all situations. Electromagnetic 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 e-sphyg 3 Digital Blood Pressure Monitor is used exceeds the applicable RF compliance level above, the e-sphyg 3 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 e-
sphyg 3 Digital Blood Pressure Monitor .b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
