Recommended separation distances between portable and mobile RF communications equipment and the S.P.E.C. 3
®
LED Curing Light.
The S.P.E.C. 3
®
LED Curing Light is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the S.P.E.C. 3
®
LED Curing Light can help prevent electromagnetic interference by maintaining a minimum distance between
the portable and mobile RF communications equipment (transmitters) and the S.P.E.C. 3
®
LED Curing Light as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using
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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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 structures, objects
and people.
