Radio Frequency Interference Statement
The equipment described in this manual generates and
uses radio-frequency energy. If it is not installed and used
properly, that is, in strict accordance with our instructions, it
may cause interference with radio and television reception.
This equipment has been tested and complies with the
limits for a Class B computing device in accordance with
the specifications in Subpart J, Part 15, of FCC rules.
These rules are designed to provide reasonable protection
against such interference in a residential installation.
However, there is no guarantee that the interference will
not occur in a particular installation, especially if you use a
"rabbit ear" television antenna. (A "rabbit ear" antenna is
the telescoping-rod type usually contained on TV
You can determine whether your computer is causing
interference by turning it off. If the interference stops, it was
probably caused by the computer or its peripheral devices.
To further isolate the problem:
● Disconnect the peripheral devices and their
input/output cables one at a time. If the interference
stops, it is caused by either the peripheral device or
its I/O cable. These devices usually require shielded
I/O cables. For Apple peripheral devices, you can
obtain the proper shielded cable from your dealer.
For non-Apple peripheral devices, contact the
manufacturer or dealer for assistance.
If your computer does cause interference to radio or
television reception, you can try to correct the interference
by using one or more of the following measures:
● Turn the TV or radio antenna until the interference
● Move the computer to one side or the other of the TV
● Move the computer farther away from the TV or
● Plug the computer into an outlet that is on a different
circuit than the TV or radio. (That is, make certain the
computer and the radio or television set are on
circuits controlled by different circuit breakers or
● Consider installing a rooftop television antenna with
coaxial cable lead-in between the antenna and TV.
If necessary, you should consult your dealer or an
experienced radio/television technician for additional
suggestions. You may find helpful the following booklet,
