iv) Plug the digital device into a different AC
outlet so the digital
device and the receiver are on different branch
circuits.
v) Disconnect and remove any I/O cables that the
digital device does not use. (Unterminated I/O
cables are a potential source of high RF emission
levels.)
vi) Plug the digital device into only a grounded
outlet receptacle. Do not use AC adapter plugs.
(Removing or cutting the power cord ground may
increase RF emission levels and may also present
a lethal shock hazard to the user.)
If you need additional help, consult your dealer,
manufacturer, or an experienced radio or
television technician.
