IEC 60601-1-2 Table 4
Guidance and manufacturer’s declaration – electromagnetic immunity
The ARTHREX HD3 is intended for use in the electromagnetic environment specified below. The customer or user of the
ARTHREX HD3 should assure that it is used in such an environment.
Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the ARTHREX HD3 Video
System, including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance

Where P is the maximum output power rating of the transmitter
in watts [W] according to the transmitter manufacturer and d is
the recommended separation in meters [m].
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey,
a
should be less that the
compliance level in each frequency range.
b
Interference may occur in the vicinity of equipment marked with
the following symbol:
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 by 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 access the electromagnetic environment due to fixed RF transmitters, and electromagnetic site survey should be
considered. If the measured field strength in the location in which the ARTHREX HD3 Video System is used exceeds
the applicable RF compliance level, above, the ARTHREX HD3 Video System should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the ARTHREX HD3 Video System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
