P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and E is
the Immunity Test Level (V/m), and d is the recommended separation distance in meters (m). Field strengths from fixed RF

frequency range. Interference 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.
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 Intraoral Scanner is used exceeds the applicable
RF compliance level above, the Intraoral Scanner should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the Intraoral
Scanner.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
