The Digital Blood Pressure Monitor is intended for use in the electromagnetic environment
specified below. The customer or the user of the 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.
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.
Electromagnetic environment - guidance
Floors should be wood, concrete or
ceramic tile. If floor are covered with
synthetic material, the relative humidity
should be at least 30%.
Power frequency magnetic fields should
be at levels characteristic of a typical
location in a typical commercial or
hospital environment.

Electromagnetic environment - guidance
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, should be less than the compliance
level in each frequency range.
Interference may occur in the
vicinity of equipment marked

Recommended separation distances between
portable and mobile RF communications equipment and the Digital Blood Pressure Monitor.
The 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 Digital Blood
Pressure Monitor can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
Digital Blood Pressure Monitor as recommended below, according to the maximum output
power of the communications equipment.

10 3.689
100 11.667
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.
Electromagnetic environment - guidance
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.
