Beat2Phone ECG Instruction Manual
The Beat2Phone ECG is intended for use in an electromagnetic environment in which radiated RF disturb-
ances are controlled. The customer or the user of the Beat2Phone ECG can help prevent electromagnetic in-
terference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Beat2Phone ECG as recommended below, according to the maximum output power of
the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in meters (m) can be determined using the equation applicable to the frequency of the transmitter, where
P
is
the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1:
At 80 MHz and 800 Mhz, the separation distance for the higher frequency range applies.
NOTE 2:
The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 MHz
to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
NOTE 3:
An additional factor of 10/3 has been incorporated into the formulae used for calculating the rec-
ommended separation distance for transmitters in the ISM frequency bands between 150 kHz and 80 MHz
and in the frequency range 80 MHz to 2.7 GHz to decrease the likelihood that mobile/portable communica-
tions equipment could cause interference if inadvertently brought into patient areas.
NOTE 4:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by ab-
sorption and reflection from structures, objects and people.
EMC test setup specified in EN 60601-2-47 Figure 202.101 was used in testing.
