The AliveCor Mobile ECG is intended for use in the electromagnetic environment specified below. The
customer or the user of the AliveCor Mobile ECG 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 the AliveCor Mobile ECG, 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 2.5 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 the
AliveCor Mobile ECG is used exceeds the applicable RF compliance level above, the AliveCor Mobile ECG
should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the AliveCor Mobile ECG.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
