Guidance and manufacturer’s declaration – electromagnetic immunity
The UP-27MD is intended for use in the electromagnetic environment specified below. The customer or
the user of the UP-27MD should assure that it is used in such an environment.
Immunity test

Electromagnetic environment – guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the UP-27MD, including cables, than the
recommended separation distance calculated
from the equation appliance to the frequency of
the transmitter.

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).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of
equipment marked with following symbol:
NOTE 1:
At 80 MHz, 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.
