Guidance and Declaration - Electromagnetic Immunity
The device is intended for use in the specified electromagnetic environment. The customer or
the user of the device should assure that it is used in such an environment as described below.

equipment should be used no closer to
any part of the system, including cables,
than the recommended separation

appropriate for the frequency of the
transmitter. Recommended separation

Where,
P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and
d is the recommended separation
distance in meters (m).

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.
