For EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING
Guidance and manufacturer's declaration - electromagnetic immunity
The arm type automatic blood pressure monitor is intended for use in the electro-
magnetic environment specified below. The customer or the user of the arm type
blood pressure monitor should assure that it is used in such an environment

Radiated RF
IEC 61000-4-3
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: 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 arm type blood pressure monitor is used exceeds the
applicable RF compliance level above, the 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 arm type blood pressure monitor..
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.

Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey,
should be less than the compliance
