Commodore 1581 - Users Manual Statement

USER'S MANUAL STATEMENT
WARNING: This equipment has been certified to comply with the limits for
a Class B computing device, pursuant to subpart J of Part 15 of the
Federal Communications Commission's rules, which are designed to pro
vide reasonable protection against radio and television interference in a
residential installation. If not installed properly, in strict accordance with
the manufacturer's instructions, it may cause such interference. If you
suspect interference, you can test this equipment by turning it off and on. If
this equipment does cause interference, correct it by doing any of the
following:
• Reorient the receiving antenna or AC plug.
• Change the relative positions of the computer and the receiver.
• Plug the computer into a different outlet so the computer and
receiver are on different circuits.
CAUTION: Only peripherals with shield-grounded cables (computer input-
output devices, terminals, printers, etc.), certified to comply with Class B
limits, can be attached to this computer. Operation with non-certified
peripherals is likely to result in communications interference.
Your house AC wall receptacle must be a three-pronged type (AC
ground). If not, contact an electrician to install the proper receptacle. If a
multi-connector box is used to connect the computer and peripherals to
AC, the ground must be common to all units.
If necessary, consult your Commodore dealer or an experienced radio-
television technician for additional suggestions. You may find the following
FCC booklet helpful: "How to Identify and Resolve Radio-TV Interference
Problems." The booklet is available from the U.S. Government Printing
Office, Washington, D.C. 20402, stock no. 004-000-00345-4.
