Uniden BC246T Owner's Manual page 9

According to the Electronic Communications Privacy Act
(ECPA), you are subject to fines and possible
imprisonment for intentionally listening to, using, or
divulging the contents of such a conversation unless you
have the consent of a party to the conversation (unless
such activity is otherwise illegal). This scanner has been
designed to prevent the reception of cellular telephone
transmissions and the decoding of scrambled
transmissions. This is done to comply with the legal
requirement that scanners be manufactured so they are
not easy to modify to pick up these transmissions. Do not
open your scanner's case to make any modifications that
could allow it to pick up transmissions that are illegal to
monitor. Modifying or tampering with your scanner's
internal components or using it in a way other than as
described in this manual could invalidate your warranty
and void your FCC authorization to operate it.
In some areas, mobile use of this scanner is unlawful or
requires a permit. Check the laws in your area. It is also
illegal in many areas (and a bad idea everywhere) to
interfere with the duties of public safety officials by
traveling to the scene of an incident without authorization.
