DESCRIPTION
Your Uniden PC78LTD is a high-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 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.
EMERGENCY OPERATIONS
1. Set the switch to CH9 or turn Channel Selector knob to Channel 9.
2. Press the microphone PTT switch and speak clearly.
3. If there is no response, select an active channel and ask that party
to relay your emergency broadcast on Channel 9.
All channels except Channel 9 may be used for normal communication.
Channel 9 is reserved by the FCC for emergency communication
involving the immediate safety of individuals or protection of property.
Channel 9 may also be used to render assistance to others.
This is an FCC rule and applies to all operators of CB radios.
