Guidance and manufacturer's declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environment
specified below. The customer or the user should assure that it is used in
such an environment.
Conducted R

NOTE I: At 80 MHz ends 800 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.

facturer and d is the recommended
separation distance in meters (m). Field
