Guidance and manufacturer´s declaration – electromagnetic immunity
The Ortholux™ Luminous Curing Light unit is intended for use in the electromagnetic environment specified
below. The customer or the user of the Ortholux Luminous Curing Light unit should assure that it is used in such
an environment.
Immunity test IEC 60601 test
Conducted RF 3 Vrms
150 kHz to 80 MHz
IEC 61000-4-6
3 V/m
Conducted RF
80 MHz to 2,5 GHz
IEC 61000-4-3
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 Ortholux Luminous
Curing Light unit is used exceeds the applicable RF compliance level above, the Ortholux Luminous Curing
Light unit should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Ortholux Luminous Curing Light unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

Portable and mobile RF communications
equipment should be used no closer to any
part of the Ortholux Luminous Curing Light
unit, including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2,5 GHz
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 metres
b
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site
a
survey, should be less than the compliance
level in each frequency range.
