Field strengths from fixed RF

transmitters, as determined by

an electromagnetic site surveya,

should be less than the

compliance level in each

frequency rangeb.

Interference may occur in the

vicinity of equipment marked

with the following symbol:

NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE2 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 device is used

exceeds the applicable RF compliance level above, the device should be observed to

verify normal operation. If abnormal performance is observed, additional measures may

be necessary, such as re-orienting or relocating the device.

b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
