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 this product is used exceeds
the applicable RF compliance level above, this product should be observed
to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating this product.
Interference may occur in the vicinity of equipment marked with the following
