the transmitter. Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey, should be less than the compliance level in each frequency range
as noted in the table. Interference may occur in the vicinity of equipment marked with the
following symbol:
.
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 system is used exceeds the applicable
RF compliance level in the table, the system should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the system.
NOTE
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE
The recommended separation distance guidelines in the following table may not apply to all
situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects, and people.
The information provided here, in conjunction with “Electromagnetic Interference” on page 61,
provides guidance on conducted and radiated interference from portable and fixed RF
transmitting equipment.
