Power frequency magnetic fields should be at levels characteristic of a typical location
in a typical commercial or hospital environment.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cord-
less) telephones and land mobile radios, amateur radio, AM and FM radio broadcast
and TV broadcast cannot be predicted theoretically with accuracy. To assess the elec-
tromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which this prod-
uct 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 symbol:
Portable and mobile RF communications equipment should be used no closer than 30
cm to any part of this product including cables.
