Product Information and Safety
Recommended separation distances between portable
and mobile RF communications equipment and the AED
The AED is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the AED can help prevent
electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the AED as
recommended below, according to the maximum output power of the
communications equipment.

d = 1.2 √P d = 2.3 √P
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 to 40.70 MHz.
Note 3:
An additional factor of 10/3 is used in calculating the recommended separation
distance for transmitters in the ISM frequency bands between 150 kHz and 80 MHz
and in the frequency range 80 MHz to 2.5 GHz to decrease the likelihood that mobile/
portable communications equipment could cause interference if it is inadvertently
brought into patient areas.
Note 4:
These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects and people.
