Introduction

Welcome to the world of CB radio communication.  Your Uniden PRO340XL
represents the most advanced portable radio ever designed for use in the
Citizens Band Radio Service.  This powerful unit operates on any of the 40 AM
frequencies authorized by the Federal Communications Commission (FCC).

Among its many features, the PRO340XL includes:

Superheterodyne circuitry

 to enhance receiver quality.

Phase Locked Loop Synthesizer

 techniques to assure precise

frequency control.

Flexible operation that allows you to power the radio with 8 AA alkaline
batteries, 10 rechargeable AA nickel-cadmium batteries (batteries not
included), or from your vehicle battery.

Connection for an optional nickel-cadmium battery charger.

This radio has been type accepted and fully certified by the FCC.

WARNING

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

Elimination Of Licensing

The Federal Communications Commission has ruled that Citizens Band Radio
Service operators are no longer required to obtain an FCC license to operate
their CB equipment.  In doing so, the FCC also permits CB stations to operate
without station identification.

Elimination of individual station licenses results in no lessening of 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 CB
Radio Service.
