Separation Distances
Table 50 Recommended Separation Distances Between Portable and Mobile RF Communications
Equipment and the LIFEPAK 15 Monitor/Defibrillator
The LIFEPAK 15 monitor/defibrillator is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the
LIFEPAK 15 monitor/defibrillator can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment
(transmitters) and the LIFEPAK 15 monitor/defibrillator 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: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: 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: 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: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
