Guidance and manufacturer’s declaration—electromagnetic immunity
Kardia Band is intended for use in the electromagnetic environment specified below. The customer or the user of Kardia
Band should assure that it is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of Kardia Band,
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2.7 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 separation
distance in meters (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 Kardia Band is used exceeds the applicable RF
compliance level above, Kardia Band should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating Kardia Band.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
