LED Curing Light, including cables, than the
recommended separation distance calculated from the
equation applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1.2√ P
d = 1.2√ P 80MHz to 800 MHz
d = 2.3√ P 800MHz to 2.5GHz
where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended minimum
separation distance in meters (m).
Field strengths from xed RF transmitters, as
determined by an electromagnetic site survey (a),
should be less than the compliance level in each
frequency range (b).
Interference may occur in the vicinity of equipment
marked with the following symbol:
Non-Ionizing Radiation
NOTE 1 At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reection
from objects, structures and people.
a. Field strengths from xed 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 xed RF
transmitters, an electromagnetic site survey should be considered. If the measured eld strength in the location in which the S.P.E.C. 3
®
LED Curing
Light is used exceeds the applicable RF compliance level above, the S.P.E.C. 3
®
LED Curing Light should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the S.P.E.C. 3
®
LED Curing Light.
b Over the frequency range 150kHz to 80MHz, eld strengths should be less than 3V/m.
