Table 17. Electromagnetic Immunity
The electrocardiograph is intended for use in the electromagnetic environment specified below. The customer or user of the electrocardiograph
should assure that it is used in such an environment.

Electromagnetic Environment - Guidance
Portable and mobile RF communications equipment should be used no closer
to any part of the electrocardiograph, including cables, than the
recommended separation distance calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance

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).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey,
a
should be less than the compliance level in
each frequency range.
b
Interference may occur in the vicinity of equipment marked with the
following symbol:
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
electrocardiograph is used exceeds the applicable RF compliance level above, the electrocardiograph should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
electrocardiograph.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
