FCC Regulations
FCC regulations permit only “transmissions”
(one party to another) rather than “broadcasts”
(to a wide audience).Advertising is not allowed
on CB Channels because it is considered 
“broadcasting.”
FCC Warnings 
Replacement or substitution of transistors, regular
diodes or other parts of a unique nature,with
parts other than those recommended by Cobra,
m ay cause a violation of the te c h n i cal re g u l at i o n s
of Part 95 of the FCC Rules,or violation of Ty pe
Acceptance requirements of Part 2 of the Rules.
Citizens Band (CB) Radio operators are not
required to obtain an FCC license to operate their
CB equipment or provide station identification.
Nevertheless,an operator of a CB radio station 
is still required to comply with the communica-
tions act and with the rules of CB Radio Operation.
