Guidance and manufacturer's declaration - electromagnetic immunity
The VEX-S300W is intended for use in the electromagnetic environment specified
below. The customer or the user of the VEX-S300W should assure that it is used in
such an electromagnetic environment.
Immunity test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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.
Field strength 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 VEX-S300W is used exceeds 3V/m, the
VEX-S300W should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
relocating the VEX-S300W or using a shielded location with a higher RF shielding
effectiveness and filter attenuation.

Electromagnetic environment -
guidance
The VEX-S300W must be used only
in a shielded location with a
minimum RF shielding effectiveness
and, for each cable that exits the
shielded location, a minimum RF
filter attenuation of 20 dB from 30
MHz to 230 MHz, 20 dB from 230
MHz to 1 GHz. Field strengths
outside the shielded location from
fixed RF transmitters, as
determined by an electromagnetic
site survey, should be less than 3
V/m.a Interference may occur in the
vicinity of equipment marked with
the following symbol:
