Portable and mobile RF communications equipment should be used
no closer to any part of the models Curing Light, 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 determined by an
electromagnetic site survey,

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:
NOTE 1 At 80 MHz end 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.
