Portable and mobile RF communications
equipment should be used no closer to any part of
Afib Talk, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.

Pis the maximum output power rating of the
transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-

Field strengths from fixed RF transmitters as
determined by an electromagnetic site survey

,
should be less than the compliance level in each
frequency range
b
. Interference may occur in the
vicinity of equipment marked with the following
symbol:
Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broad cast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
Afib Talk is used exceeds the applicable RF compliance level above, it should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the device.
b
Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
