Guidance and Manufacturer’s Declaration – Electromagnetic Immunity

The EUT is intended for use in the electromagnetic environment specified below. The
customer or the user of the EUT should assure that it is used in such an environment.

The EUT must be used only in a shielded
location with a minimum RF shielding
effectiveness and, for each cable that enters
the shielded location with a minimum RF
shielding effectiveness and, for each cable
that enters the shielded location
Field strengths outside the shielded location
from fixed RF transmitters, as determined
by an
electromagnetic site survey, should be less
than 3V/m.

Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE 1) These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
NOTE 2) It is essential that the actual shielding effectiveness and filter attenuation of the shielded
location be verified to assure that they meet the minimum specification.
a
Field strengths from fixed 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 field strength
outside the shielded location in which the EUT is used exceeds 3V/m, the EUT should be observed to
verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as relocating the
EUT or using a shielded location with a higher RF shielding effectiveness and filter attenuation.
