Guidance and manufacturer’s declaration - electromagnetic immunity
The EzRay Premium is intended for use in the electromagnetic environment
specified below. The customer or the user of the EzRay Premium should assure that
it is used in such an electromagnetic environment.

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 near
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.
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 EzRay Premium is used exceeds 3V/m,
the EzRay Premium should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
relocating the EzRay Premium or using a shielded location with a higher RF
shielding effectiveness and filter attenuation.
