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 electromagnetic
environment.

The EUT must be used only in a shielded location
with a minimum RH shielding effectiveness nad, 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.
