Guidance and manufacturer’s declaration –electromagnetic immunity
The ProBP™ 2000 Digital Blood Pressure Device is intended for use in the electromagnetic environment specified below.
The customer or the user of the ProBP™ 2000 Digital Blood Pressure Device should assure that it is used in such an
environment.

Recommended separation distance
Portable and mobile RF communications equipment
should be used no closer to any part of the ProBP™ 2000
Digital Blood Pressure Device, including cables, than the
recommended separation distance calculated from the
equation appropriate for the frequency of the
transmitter.

occur in the vicinity of equipment
marked with the following symbol:
Note1: 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.
