Interference may occur in the vicinity of
equipment marked with the following
symbol:
Note 1
: At 80 MHz to 800 MHz, the separation distance for the higher frequency range applies.
Note 2 : These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
Note 3
: The device that intentionally receives RF electromagnetic energy at the
exclusion band
(2395.825MHz-2487.645MHz) is exempt from the ESSENTIAL PERFORMANCE requirements,
but remains safe.
