to 2,5 GHz
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
a ected by absorption and reflection from structures, objectsand people.
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 LED Curing Light
LED-3200 is used exceeds the applicable RF compliance level above, the Medical LED
Curing Light LED-3200 should be observed to verify normal operation. If abnormal
perfromance is observed, additional measures may be necessary, such as reorienting or
relocating the LED Curing Light LED-3200.
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than [v1] V/m.
Recommended separation distance
d=1.2√ P
d=1.2√ P 80MHz to 800MHz
d=2.3√ P 800MHz to 2.5GHz
w here 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(m). Field
3 V/m
strengths from fixed RF transmitters, as
determined by an electromagnetic site
survey, should be less than the com-
pliance level in each frequency range.
lnterference may occur in the vicinity of
equipment marked with the following
symbol: NOTE 1 At 80 MHz and 800
MHz, the higher frequency range applies.
