❑ The computer uses high-frequency radio signals and may cause interference
to radio or TV reception. Should this occur, relocate the computer a suitable
distance away from the set.
❑ Use only specified peripheral equipment and interface cables; otherwise,
problems may result.
❑ Do not use cut or damaged connection cables.
❑ If the telephone company makes a service call to your home or office and
determines that your computer is responsible for a problem, the telephone
company may bill you for the service call. Also, if you do not disconnect
your computer when it is adversely affecting the telephone line, the
telephone company has the right to disconnect your service until you correct
the problem.

computer and then unplug it. You may want to have the computer checked by
qualified personnel before operating it any further.
