Apple Macintosh PowerBook 180 computers - Manual (Page 15)

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:
■ Turn the television or radio antenna until the interference stops.
■ Move the computer to one side or the other of the television or radio.
■ Move the computer farther away from the television or radio.
■ 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 your authorized Apple dealer or 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.
