Guidance and manufacturer's declaration - electromagnetic immunity for EQUIPMENT and
SYSTEMS that are not LIFE-SUPPORTING
Guidance and manufacturer's declaration – electromagnetic immunity
This camera is intended for use in the electromagnetic environment specified below. The
customer or the user of this camera should assure that it is used in such an environment.
Immunity test
IEC 60601
test level
Conducted RF
3 Vrms
IEC 61000-4-6
150 kHz to
80 MHz
Radiated RF
3 V/m
IEC 61000-4-3
80 MHz to
2.5 GHz
NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people
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 this camera is used exceeds the appli-
cable RF compliance level above, this camera should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating this camera.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Portable and mobile RF communications
equipment should be used no closer to any
part of this camera, including cables, than
the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

according to the transmitter manufacturer
and d is the recommended separation

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
