Recommended Separation Distances between Portable and Mobile RF Communications
Equipment and the LIFEPAK 20 Defibrillator/Monitor Series
The LIFEPAK 20 Defibrillator/Monitor is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the LIFEPAK 20 Defibrillator/Monitor can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the LIFEPAK 20 Defibrillator/Monitor 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 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.
