Compatibility Information
System Classes
Please read all of the following information to determine the class of system you
have and the environment in which it should be installed and operated.
In the United States, the Federal Communications Commission (FCC) governs the
levels of electromagnetic emissions from a digital device. Electromagnetic emissions
can interfere with radio and television transmission. To reduce the risk of harmful
interference, the FCC has established requirements for manufacturers of digital
devices.
A manufacturer of a digital device must test and label the product to inform an end-
user of the maximum emission level from the product when used in accordance with
its instructions. The FCC has established two classes of levels, Class A and Class B.
A system that meets the FCC Class A requirements may be marketed for use in an
industrial or a commercial area. A system that meets the more stringent FCC Class B
requirements may be marketed for use in a residential area in addition to use in an
industrial or a commercial area.
An end-user in the United States is responsible for ensuring that his system is
suitable for its environment as stated in the above paragraph and bears the financial
responsibility for correcting harmful interference.
For a system to be considered an FCC Class B system, all peripherals of the system
(workstation, monitor, keyboard, mouse, external disk and tape drives, modem,
printer, etc.) must be labeled as such. If any peripheral or the system itself is labeled
as FCC Class A, the entire system becomes FCC Class A and should not be used in a
residential area.
