Introduction

Welcometothe exciting world ofCB radio communications! Your UnidenGRANT XL
CitizensBand Mobile Transceiver represents the highest quality communincations
devicedesigned for use in the CitizensBand Radio Service. This powerful unit
operates on any ofthe 40 AM, 40 LBS, and 40 USBchannels authorized by the
Spectrum Management Agency(SMA).

Among its many features,tbe GRANTXLincludes:

. SSB (single-sideband) operation inaddition to standard AM operation
. Dual noise reduction circuitry- Noise Blanker and Automatic Noise Limiter

. Multi-function Meter - Measures incoming Signal Strength, RP transmitter

outputpower, and SWRreadings

. RP Gain Control- Provides optimumreceiving capabilityinboth AM and SSB

operating modes

. Adjustable Microphone Gain Control
. Clarifier Control- For fme-tuning of SSB signals
. Public AddressSystem capability

WARNING

The Citizens Band Radiocommunication Service (CBRS) is under the
jurisdiction of the Australian Spectrum Management Agency (SMA).
Any adjustment or alteration which will change the performance of
the transceiver's original SMAtype acceptance is STRICTLYPROHI-

BITED. Replacement or Substitution of power or frequency determi-
ning components e.g. Crystals, Transistors, ICs, Diodes, etc. with
other than those recommended by UNIDENwillcause violation to the
SMAtype acceptance technical requirement.

Licensing Requirements

Before using your transceiver, you must obtain a CitizensBand RadioLicense from
the Spectrum Management Agency(SMA). Application forms and brochures relating
to CBRS are available at your nearest SMA office. Mail the completed application
form and the.appropriate feeto the Communications Manager, in the State or
Territory in which the station willbe operated.

1. MIC(Microphone)GAINControl- Use to adjust themicrophone gain during

transmitting. At the maximum setting, you have fulltalk power during transmitting
while holding themicrophone ata comfortable distance. In the PA (Public
Address) mode, thiscontrol adjusts the output volumeof thePA speaker.

2. VOl(Volume)Control- Use to turn the power on or off, and to adjust the
receiving audio level.

3. sa (Squelch)Control- Use to eliminatebackground noise during the absence of a
signal. Turn the Squelch Control fullycounterclockwise,then slowlyrotate it
back clockwiseuntil all noise disappears. Atthis setting, any signalmustbe
slightly stronger than thebackground noise to break squelchand be heard.
Rotating the control farther clockwise increases the thresholdlevel below which
weak signalsare not heard. At the maximum clockwise setting,only the strong
signals can break squelch and be heard.

4. RFGAINControl- For normaloperation, keep the RF Gain Control at the full

.clockwise position. Turn counterclockwisetoreduce incoming signalgain when a

signal is strong enough to saturate your receiver.

5. SWRCAl Control- Use to calibrate the meter for SWR (standing-wave ratio)
measurements. Make surethe Mode Selector (7) is set to the AMposition. Turn
the Meter Selector (6) to the CAlposition. Press and hold the microphone PTT
(push-to-talk) Switch. Turn the SWR CAL Control to adj~st the needle to the ...
position on the SWR meter. Then turn the Meter Selector to the SWRposition to
measure the standing-waveratio of your antenna system. A lower reading
indicates better antenna matching.

6. Meter(SlRFCAl SWR)Selector - Use to selectthe function of the meter. For

normal operation, always set to the SIRF position. The SWR and CAl positions are
for SWR measurement only. (See "Multi-Function Meter" on page 7 for related

information.)

7. Mode (lSB AMUSB) Selector
USB) for both the transmitter and receiver. In SSB (single-side band) mode you
are allowed to transmit 12 watts PEP power. Therefore, you can communicate at
far greater distances than with conventional AM mode operation. Because not all
the CBers are equipped with SSB mode, you can always select AM mode for
nQrmal CB communications. (For more details, see" About SSB" in the Operation

- Use to select the mode of operation (AM, LSB, or

section.)

8. CLARIFIERControl- Usetofme-tunetheSSBreceivingsignals.TheClarifier

Control is providedprimarily for SSBmode operations. It can alsobe used inAM
mode operation to optimize receiving signals.

The selected cbannel is displayed on tbe LED readout, directly above the cbannel
selector knob. Use Cbannel9 for emergency communication only. Because
Cbannel 9 is reserved for emergency operation only, you cannot transmit on this
channel for non-emergency purposes. However, you may momtor Cbannel 9
anytime you wisb to do so.

Important: All channels, except Channel 9, may be used for nor-

mal communication. Channel 9 is reserved for emergency com-
munications involving the immediate safety of individuals or the

protection of property.
