Your Uniden 

PC78LTW

represents the highest quality communications device

designed for use in the Citizens Band Radio Service. It will operate on any of the
40 AM frequencies authorized by the Federal Communications Commission (FCC).  

The FCC has ruled that CB Radio Service operators are no longer required to
obtain an FCC License to operate their CB equipment. In doing so, the FCC also
decided to permit CB station operation without station identification.

Elimination of individual station licenses does not reduce the operating
privileges or responsibilities of CB users. An operator of a CB radio station is still
required to comply with the Communications Act and with the rules of Citizens
Band Radio Service

.

The Citizens Band Radio Service is under the jurisdiction of the
Federal Communications Commission (FCC). Any adjustments or
alterations which would alter the performance of the transceiver's
original FCC type acceptance, or which would change the
frequency determining method, are strictly prohibited.
Replacement or substitution of crystal, transistors, ICs, regulator
diodes, or any other part of a unique nature, with parts other than
those recommend by Uniden, may cause violations of the
technical regulations in Part 95 of the FCC Rules or in violation of
type acceptance requirements in Part 2 of the rules.
