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

cables, than the recommended

Interference may occur in the
vicinity of equipment marked with the

Radiated RF

3 V/m
80 MHz to 2,5 GHz

Note 1: At 80 MHz and 800 MHz, the higher frequency applies.
Note 2: These guidelines may not apply in all situations. Electr
omagnetic propagation is affected by absorption
and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stat
ions for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM 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 in the location in which the Stratus OCT is used exceeds the applicable
RF compliance level above, the Stratus OCT should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the Stratus
OCT.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
