Guidance and manufacturer's declaration –electromagnetic immunity
The Gendex Oralix AC is intended for use in the electromagnetic environment specified below. The
customer or the user of the Gendex Oralix AC should assure that it is used in such an environment.
IEC 60601 test
Immunity test
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2,5
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 the
Gendex Oralix AC is used exceeds the applicable RF compliance level above, the Gendex Oralix AC should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Gendex Oralix AC.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part of
the Gendex Oralix AC, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.

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 distance in meters (m).
Field strengths from fixed RF transmitters, as deter-
mined by an electromagnetic site survey,
be less than the compliance level in each
frequency range.
