equipment should be

Where P is the maximum
output power rating
of the transmitter in
watts (W) according
to the transmitter
manufacturer and d
is the recommended
separation distance in
meters (m).
Field strengths from

should be less
than the compliance
level in each frequency
range.

Interference may occur in
the vicinity of equipment
marked with symbol:
At 80 MHz and 800 MHz, the higher frequency range applies.
3. 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 broadcast 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 the Eonis is used exceeds the applicable RF compliance level above, the Eonis should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Eonis.
4. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than3V/m.
