The Citizens Band lies between the shor twave
broadcast and 10-meter Amateur radio bands and
was established by law in 1949. The Class D two -
way co m m u n i cations serv i ce was opened in 1959.

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 oper ate their
CB equipment or provide station identification.

Nevertheless, an operator of a CB radio station 
is still required to comply with the communic a-
tions act and with the rules of CB Radio Operation.

In Vehicle Use

Note

Due to the characteristics of 
CB transmissions, it is neccesary
to use an external car roof
antenna (item #ATW 400) and a
BNC adapter (item #CA 43) to
receive optimal performance
while in your vehicle. See
Accessories section on page 19.

Note

DC/Power Cord is provided.

Auto Battery
Save

Note

Auto Battery S ave will not 
effect the receiving range of 
the HH 34.

Battery life is approximately
20 hours under normal use 
conditions.

A Few Rules 
You Should Know

Operation

How Your CB Can Serve You

Note

TX/BATT indicator will illuminate
red when the batteries need
recharging or replacement.

Note

Battery life is increased up to 50%
while in Battery Save LOW Mode.
This reduces power output to 1
watt.

Power Saver-HI/LOW

Reduces the power to 1 watt. This does not
decrease the unit’s ability to receive but does
reduce the transmitting range.

To utilize Power Save slide switch to LOW.
This mode will extend the unit’s battery life.

1

The HH 34 can be connec ted to your cigarette
lighter with the provided car cord.

This power

connection does NOT charge the batteries.
