should be used no closer to any
part of the 1417WCC/WGC,
including cables, than the
recommended separation

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 and d
is the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as deter-mined by
an electromagnetic site survey,
(a) 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:
Note 1) Uт is the A.C. mains voltage prior to application of the test level.
Note 2) At 80 MHz and 800 MHz, the higher frequency range applies.
Note 3) 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 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 the
location in which the 1417WCC/WGC is used exceeds the applicable RF compliance level above, the
1417WCC/WGC should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the 1417WCC/WGC.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V / m.
