Recommended Separation Distances from RF Equipment for E Series Life-Support
Functions

The life-support functions

of the E Series unit is intended for use in an environment in which radiated RF disturbances

are controlled. You can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the E Series unit as recommended below,
according to the maximum output power of the communications equipment.

The life-support functions on the E Series unit are defined to be any function associated with Pacing and Defibrilla-

tion. Specifically, these functions include, but are not limited to, the pacing pulse output and defibrillation energy dis-
charge.

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 max-
imum 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.
