Lincoln 1997 Town Car Owner's Manual page 276

NOTE: Mobile communications systems may harm
the operation of your vehicle, particularly if they are
not properly designed for automotive use or are not
properly installed. For example, when operated,
such systems may cause the engine to stumble or
stall. In addition, such systems may themselves be
damaged or their operation affected by operating
your vehicle. (Citizens band [CB] transceivers,
garage door openers, and other transmitters whose
power output is 5 watts or less will not ordinarily
affect your vehicle's operation.)
NOTE: Because we have no control over the
installation, design, or manufacture of such systems,
Ford cannot assume responsibility for any adverse
effects or damage that may result if you use this
equipment.
