TES 3650
The Digital Blood Pressure Monitor is intended for use in the electromagnetic environment specified below. The customer or the
user of Digital 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 Digital Blood Pressure Monitor is used exceeds the applicable RF compliance level above,
the 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 Digital Blood Pressure Monitor.
b
Over the frequency range 150 KHz to 80MHz, field strengths should be less than 3V/m.

± 6 kV Floors should be wood, concrete or ceramic tile. If floor are covered with
contact synthetic material, the relative humidity should be at least 30%.
± 8 kV aie
Power frequency magnetic fields should be at levels characteristic of a
3 V/m
typical location in a typical commercial or hospital environment.
Portable and mobile RF communications equipment should be used no
closer to any part of the Digital 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=1.167 P 80 MHz to 800 MHz
√
d=2.333 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
3 V/m
separation distance in metres (m).
