87 / 93 page Outlines of Major Noise Regulation Standards !Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc. • This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering. 85 C50E.pdf Aug.28,2008 (1) Class A recommended to be measured with 10m distance. Class B recommended to be measured with 3m distance. (2) The FCC Part 15 regulation controls radiated interference by establishing quasi-peak and mean value limits for fre- quencies ranging from 30MHz to 40GHz (or maximum frequency's fifth harmonic, whichever is lower). For AC main ports, the FCC Part 15 regulation controls main terminal interference voltage by establishing quasi- peak value limits for frequencies ranging from 450kHz to 30MHz. (3)There is no regulation on power interference. On the border frequency, lower limit should be applied. Class A Equipment: The digital equipment that is sold for commercial, industrial and office use. Class B Equipment: The digital equipment that is sold to be used in residential areas.
