Recommended Separation Distances from RF Equipment for E Series
Non-Life-Support Functions
The non-life-support functions
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.

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 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.

The non-life-support functions on the E Series unit are defined to be any function not listed as a life-support function
in the "EID for Life Support Functions" table (Note a). Specifically, these functions are noninvasive blood pressure
