Librestream Onsight 2500 Regulatory and Safety Guide

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.
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 equipment is used exceeds the applicable RF compliance
level above, the equipment should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the equipment
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
