Appendix J: Electromagnetic Compatibility (EMC)
Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The Nanoduct system is intended for use in the electromagnetic environment specified below. The customer or the
operator of the Nanoduct system should assure that it is used in such an environment.

NOTE 1: At 80 MHz and 800 MHz, 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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
a
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 Nanoduct system is used exceeds
the applicable RF compliance level above, the Nanoduct system should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
Nanoduct system.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

according to the transmitter
manufacturer and is the
recommended separation

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

the compliance level in each
frequency range. b
