NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
is affected by absorption and reflection from structures, objects and people.

a Field strengths from 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 filed strength in the location in which the Otoscope is used
exceeds the applicable RF compliance level above. The Otoscope should
be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or
relocating the Otoscope.
b Over the frequency range 150kHz to 80 MHz, filed strengths should be
less than 3V/m.
