Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the KWIKtrak Turntable,
including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the
transmitter.

Recommended separation distance
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.
Field strengths from fixed RF transmitters, as determined by
an electromagnetic site survey,
(a)
should be less than the
compliance level in each frequency range.
(b)
Interference may occur in the local area of product marked
with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: Theses directions may not apply in all situations. Electromagnetic propagation if 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 in the location in which the KWIKtrak Turntable is used
exceeds the applicable RF compliance level above, the KWIKtrak Turntable should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the KWIKtrak Turntable.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
