Barco Coronis Uniti MDMC-12133 User Manual page 55

Immunity test
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is af-
fected by absorption and reflection from structures, objects and people.
Recommended separation distance
The Coronis Uniti is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer of the user of the Coronis Uniti can help prevent electromagnetic interfer-
ence by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Coronis Uniti as recommended below, according to the maximum output power of
the communications equipment.
3. 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 in the
location in which the Coronis Uniti is used exceeds the applicable RF compliance level above, the Coronis Uniti should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Coronis Uniti.
4. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
