Radio And Television Interference - Commodore 1084S Manual

Radio and Television Interference
This monitor generates and uses radio frequency energy. If not
. properly installed and used in strict accordance with the manufac-
turer's instructions, this equipment may interfere with radio and
television reception. This machine has been tested and found to
comply with the limits for a Class B computing device in accor-
dance with specifications in Part 15, Subpart
J
of FCC rules, which
are designed to provide reasonable protection against such inter-
ference in a residential installation. If you suspect interference, test
this equipment by turning it off and on. If you determine that there is
interference with radio or television reception, try one or more of
the following measures to correct it:
• Reorient the receiving antenna.
• Move the computer and the monitor away from the receiver
that is picking up the interference.
• Change the relative positions of the computer and the
receiver.
• Plug the computer into a different outlet so that the computer
and the receiver are on different branch circuits.
CAUTION: Only peripherals with shield-grounded cables (comput-
er input-output devices, terminals, printers, etc.), certified to comply
with Class B limits, can be attached to this monitor. 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 recepta-
cle. 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 dealer or an experienced radio/television
technician for additional suggestions. You may also consult the
following booklet prepared by the Federal Communications Com-
mission: How to Identify and Resolve Radio - TV Interference
