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