FCC statement
This equipment has been tested and found to comply with the limits for a Class B digital device
in accordance with the specifications in Part 15 of FCC rules. See instructions if interference to
radio or television reception is suspected.
Radio and television interference
The equipment described in this manual generates, uses, and can radiate radio-frequency
energy. If it is not installed and used properly—that is, in strict accordance with Apple’s
instructions—it may cause interference with radio and television reception.
This equipment has been tested and found to comply with the limits for a
Class B digital device in accordance with the specifications in Part 15 of FCC rules. These
specifications are designed to provide reasonable protection against such interference in a
residential installation. However, there is no guarantee that interference will not occur in a
particular installation.
You can determine whether your computer system is causing interference by turning it off. If
the interference stops, it was probably caused by the computer or one of the peripheral devices.
If your computer system does cause interference to radio or television reception, try to correct
the interference by using one or more of the following measures:
m Turn the television or radio antenna until the interference stops.
m Move the computer to one side or the other of the television or radio.
m Move the computer farther away from the television or radio.
m Plug the computer into an outlet that is on a different circuit from the television or radio.
(That is, make certain the computer and the television or radio are on circuits controlled by
different circuit breakers or fuses.)
If necessary, consult the service and support information that came with your computer for
instructions on how to contact an Apple-authorized service provider or Apple for assistance. Or
consult an experienced radio/television technician for additional suggestions. You may find
helpful the following booklet, prepared by the Federal Communications Commission:
Interference Handbook (stock number 004-000-00345-4). This booklet is available from the
U.S. Government Printing Office, Washington, DC 20402.
IMPORTANT Changes or modifications to this product not authorized by Apple Computer, Inc.,
could void the FCC Certification and negate your authority to operate the product.
This product was tested for FCC compliance under conditions that included the use of shielded
cables and connectors between system components. It is important that you use shielded cables
and connectors to reduce the possibility of causing interference to radios, television sets, and
other electronic devices. For Apple peripheral devices, you can obtain the proper shielded
cables through an Apple-authorized Apple dealer. For non-Apple peripheral devices, contact the
manufacturer or dealer for assistance.
