Your Uniden Grant LT 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
.
1. Turn the Channel Selector 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.
Uniden is a registered trademark of Uniden America Corporation.

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.
DDeessccrriippttiioonn
Features, Specifications, and availability of Optional
Accessories are subject to change without notice.
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 a motorist.
This is an FCC rule and applies to all operators of CB radios.

MOUNTING THE RADIO BRACKET
1. Select a location that is convenient for operating the radio, but does not
interfere with the driver or passenger.
2. Remove the mounting bracket from radio and use it as a template for
marking the location of the mounting screws.
3. Drill the necessary holes and secure the mounting bracket in place using
mounting screws.
MOUNTING THE MICROPHONE HANGER
Mount the microphone hanger to the side of the radio. Mounting holes are provided
near the microphone connector and on the other side of the unit. Use the screws
supplied. You can also mount the hanger on the dashboard, if preferred.
CONNECTING THE POWER CORDS
1. Check the vehicle battery connections to determine which battery terminal
(positive or negative) is grounded to the engine block or chassis. Most of
today’s vehicles use a negative ground. If your vehicle has a negative
ground, follow steps 2 and 3.
2. Connect the RED wire of the DC power cord to the accessory contact in
your vehicle’s +13.8 VDC fuse box.
3. Connect the BLACK wire of the DC power cord to the negative side of the
automobile (usually the chassis).
4. Plug the DC power cord into the Power Connector on the rear panel.
Plan the location of the transceiver and
microphone bracket before beginning installation.
IInnssttaallllaattiioonn
In vehicles with a positive ground, the RED wire connects to
the chassis and the BLACK wire connects to the accessory
contact in the fuse box.

Connecting the Antenna
Connect the CB antenna plug to the Antenna Connector on the rear panel. (For
more information on antenna installation, please refer to the instruction guide that
came with your antenna.)
CB Antenna Tips
●A vertically polarized quarter-wavelength whip antenna provides the most
reliable operation and greatest range. The shorter loaded type whip
antennas are more attractive and compact than the larger full quarter-
wavelength whip. Although the reduced height decreases possible
clearance problems, the shorter antennas may not provide the same
transmitting and receiving range possible with the longer ones.
●A 3-way combination antenna allows you to operate all three bands (AM,
FM, and CB) with one antenna. However, it will provide a shorter
transmitting and receiving range than a standard “single band” antenna
designed for CB use only. You may also notice a higher SWR with this type
of antenna.
Connecting an External Speaker (Optional)
Connect an optional external speaker to the External Speaker Jack on the rear of
the transceiver. For the external speaker, use an 8W speaker with at least a 4-watt
rating. When connected, the external speaker automatically disables the internal
speaker. The external speaker will provide high performance remote receiver
monitoring.
Connecting a Public Address (PA) Speaker (Optional)
Connect an optional Public Address speaker to the PA Speaker Jack on the back of
the transceiver. For the PA speaker, use an 8W speaker with at least a 4-watt rating.
Be sure the PA speaker is directed away from the microphone to avoid acoustic
feedback. When you are operating the PA system with high output level, greater
separation and isolation between the microphone and PA speaker may be required
to prevent feedback. When this unit is used as a public address system, set the
CB/PA Switch to the PA position.
MOUNTING THE RADIO TO THE BRACKET
1. Align the mounting holes on both sides of the radio with the holes on the
mounting bracket.
2. Insert the mounting knobs and tighten the knobs until the radio
is secure.
To avoid damaging the radio casing, do not overtighten
the knobs.

1. Turn unit ON and set
VOLUME Control to a
comfortable level.
2. Select CHANNEL .
3. Set switch to NB/ANL .
Dynamic Squelch Control automatically sets Squelch to the optimal level for stronger
transmission and signal clarity. To scan for weaker signals, turn Dynamic Squelch
Control off and perform the following steps:
4a. Turn SQUELCH fully clockwise so only strong
signals can get through.
4b. Turn SQUELCH fully counter-clockwise until you
hear a hiss. Everything gets through - noise, weak
signals, and strong signals.
4c. Turn SQUELCH back clockwise until the hiss stops.
Only clearer signals get through.
Be sure that the power source, antenna, and microphone
are properly connected before proceeding.
TTooRReecceeiivvee
Set SQUELCH only when the
radio is not receiving a
strong signal.

5. Adjust RF GAIN knob to optimize reception
in strong signal areas.
6. Adjust CLARIFIER knob to reduce or eliminate
adjacent channel interference.
7. Set the meter selector to S/RF .
1. Select a channel.
2. Adjust
MIC GAIN .
3. When the channel is clear, press the
microphone PTT switch and speak.
TTooTTrraannssmmiitt
If the channel is busy, do not transmit until it becomes clear.

SWR Meter:Measures SWR (standing wave ratio) of antenna. Use to check antenna
system or to adjust your antenna to the proper length.
To measure
SWR :
1. Set the Mode Selector to the
AM position.
2. Set the Meter Selector
to the
CAL position.
3. Press and hold the microphone
PTT Switch. (Transmit)
4. Calibrate the meter using the
SWR CAL Control. (Adjust the
needle to the ▼mark.) Do not
talk into the microphone or set
the MIC GAIN Control to the
MIN position.
5. Move the Meter Selector to the SWR position while holding the PTT Switch.
A reading below 2 is acceptable. Higher readings indicate a problem in the antenna
system. Problems may be caused by humidity, vibration, or corrosion. Check both
ends of the coaxial cable connector. Also check for damage to the cable or antenna.
