Guidance and manufacturer's declaration – electromagnetic immunity
The IMAGE1 S™ 4U camera head is intended for use in the electromagnetic environment specified below. The user of the IMAGE1 S™ 4U camera
head should make sure that it is used in such an environment.

Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situations. The propagation of electromagnetic quantities is affected by absorptions and reflections of buildings,
objects, and persons.
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 in the location in which the 4U camera head is used exceeds the
applicable RF compliance level above, the 4U camera head should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re­orienting or relocating the 4U camera head.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Compliance level Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the IMAGE1 S™ 4U camera head,
including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
