UNIDEN Model uh015sx UHF CB Radio
Introduction
The Uniden uh015sx is designed to provide you with years of trouble free service. Its rugged
components and materials are capable of withstanding harsh environments. Please read this
Operating Manual carefully to ensure you gain the optimum performance of the unit.
The citizen band radio service is licenced in Australia by ACMA Radio-communications
(Citizen Band Radio Stations) Class Licence and in New Zealand by MED General
User Licence for Citizen Band Radio and operation is subject to conditions contained in
those licenses.
Features
Preventative Maintenance:
The following system checks should be made every six to twelve months:
! Check the Standing Wave Ratio (SWR).
! Inspect the tightness of all electrical connections.
! Inspect the antenna coaxial cable for wear or breaks on the shielding.
! Inspect the tightness of all screws and other mounting hardware.
Troubleshooting:
Should the unit malfunction or perform poorly, follow these procedures:
If the transceiver is completely inoperative: Check the power cord and fuse.
If there is trouble with receiving: Check the VOLUME control setting. Be sure the SQUELCH is
adjusted properly. Possibly the radio is over-squelched.
If there is trouble with transmitting: Check that the transmission line (coaxial cable) is
securely connected to the ANTENNA connector. Check that the antenna is fully extended for
proper operation. Check that all transmission line (coaxial cable) connections are secure and free
of corrosion.
Blackening may occur on the Liquid Crystal Display if the uh015sx has been
subjected to extreme high temperature (above 60°C) . This is not a fault. Normal LCD
operation resumes when the temperature stabilizes back to standard operating

The radio can be mounted complete - or - with the Display Unit remote of the
Transceiver.
Mounting the complete radio (Transceiver with Display Unit)
a) Plug in display cable from the
Display Unit to the transceiver.
b) Hinge the Display Unit into the
transceiver as shown in the
diagram, then snap closed.
c) Should you wish, at a later stage,
to position the Display Unit
remote from the Transceiver,
release the Display Unit by
pushing up the slide on the side.
Remote mounting of the Transceiver Unit
If the Display Unit is not already
separate of the Transceiver then
remove it as detailed in c) above.
Fix the Transceiver Mounting Bracket
in an appropriate location (screws
and washers supplied). Then fix the
Transceiver in the bracket using the
Knob bolts supplied d).
The bracket can be fixed on the top
or under the transceiver. An arced
slot e) allows you to mount the
transceiver at an angle.
Changing Remote Extension Cable
At the back of the Display Unit
unscrew the cable cover A) and
release bracket B).
Unplug the short cable C) and plug in
the extension cable.
Replace bracket B) over the cable.
Then replace back cover A) and
screw in place.

Fixing the Display Rear
Bracket
To mount the Display Unit it needs to
be fitted with a Display Rear Bracket
(included in package).
a)Position the Display Rear Bracket
so that one end fits over the two
studs at the end of the Display
Unit.
b)Push it into place until the fixing
screw hole is aligned with its
threaded counterpart.
c)Secure the Display Rear Bracket
with the screw provided.
Optional mounting positions
The Display Unit can be mounted from the top, back or bottom.
d) Fix the Display Mount Bracket in place (above, at the
rear or at the bottom) by screwing through the
slots in the bracket.
e) Fix the Display Unit to the bracket with the
thumb screws provided.
f) Connect the Extension Cable between the Display
Unit and the Transceiver.
Setting the Squelch
Turn the Unit ON by rotating the volume control clockwise. The uh015sx
has 3 preset squelch levels:
1 - max sensitivity (min squelch)
2 - med sensitivity (med squelch)
3 - min sensitivity (max/tight squelch)
It requires no adjustment.
Press and hold MON . The squelch will flash.
Turn rotary knob to select. Press MON to set.
The SQT icon appears if level 3 is selected.
! Selecting tight squelch mode may prevent the
reception of weak signals.
! High noise areas may still break the squelch.

Monitor
Press MON to open the
squelch and receive all
weak signals.
Press MON again
momentarily to cancel.
Selecting a Channel/POLICE and CB Channel Groups
Turn the Rotary Channel Selector to select the desired channel.
The uh015sx has two groups of channels to select from. When the CB icon is showing
the 40 UHF-CB and any user programmed RX channel will be available for selection or
scanning. When the POLICE icon is showing then the 115 police frequencies will be
available. Press POL to select which group(s) to activate or deactivate.
For your reference a list of the
available UHF CB channels,
corresponding frequencies and
guidelines for their use is printed
on page 36. For Australia,
Channels 05 and 35 are
reserved for Emergency Calls.
The 40 UHF-CB channels are numbered 1-40. The programmable RX channels are
numbered 41-100 (100 is shown as o0) - and only show when programmed. The 115
police frequencies do not have channel numbers but you can still select them ( - appears in the channel display) or copy them to a programmable RX channel.

UNIDEN Model uh015sx UHF CB Radio
Operation
Transmitting
The uh015sx uses the 40 UHF-CB Channels. See page 36 for
UHF-CB Channels & Frequencies.
Channels 22 and 23 are for telemetry and
telecommand applications. Transmit is
inhibited on these channels.
Select the desired channel. Press the microphone's PTT button and speak normally
into the microphone. Hold it approx. 7cm from your mouth. The TX icon appears while
transmitting. Release the PTT button to end the transmission and listen for a reply.
Using Repeater Channels (Duplex Mode)
UHF CB repeaters are used to retransmit or relay your signal. Repeaters will extend
the range of your radio and overcome the shielding effect caused by solid
obstructions. In normal Simplex operation, your radio transmits on one particular
frequency and receives on that same frequency. If there is a barrier that partially
blocks your transmitted signal, the probability of another radio receiving the signal is
very slim. Hills, tall buildings, metallic structures,...etc tend to act as a screen between
radios.
Standard Operation without the aid of a
Repeater Station.
Operation with the aid of a Repeater
Station (Duplex).
The signal coming from your radio is received by the Repeater Station and then
re-transmitted at the same time on another channel. This operation is called
"Duplexing".
For example,
CH01 on Duplex Mode will Receive on CH01 but Transmit on CH31
CH02 on Duplex Mode will Receive on CH02 but Transmit on CH32 etc...
If you transmit on CH01 Duplex mode, you are actually transmitting on CH31 the
repeater station down-coverts your signal and retransmits on CH01.

Operating the uh015sx in Duplex Mode
For this example we are adopting CH01 as the channel being used in your area for
repeater use.
To Set Duplex ON/OFF
Press once. The DUP setting
will flash. Turn the rotary knob to adjust
the setting to or . Press & hold
/ENTER to set. A confirmation
tone sounds.
The DUP icon appears.
! Only channels 01 - 08 are available for Duplex.
! Check with your local Retailer for information on available repeaters.
! If a button is not pressed within 10 seconds the uh015sx will automatically exit MENU Mode.
Scanning
The uh015sx scanning feature allows you to search the SCAN MEMORY for active
channels automatically.
The scan memory has two main groups; Open Scan (OS) and Group Scan (GS), OS
Scan searches all the channels and frequencies in its memory continuously. GS Scan
has the ability of monitoring a priority channel every 1.5 seconds while searching
channels and frequencies in its memory.
Furthermore, while scanning you can select which channel groups to activate (CB or
POLICE).
Press and Scanning starts.
The SCN icon appears.
You may change the scan direction by
turning the rotary channel selector.
Press again to exit scanning.
Open Scan (OS) Mode
Allows continuous scanning of channels stored in the Open Scan memory. If an active
channel is found, scanning will stop on that channel.
This example shows CH17 active.
If the received signal ceases, the unit will wait 3
seconds for the signal to return, otherwise scanning
resumes. During Scan you may...
! Press to hold scan. Press again to resume scan.
! If scan stops on a frequency and you wish to continue then turn rotary channel
selector.
! The direction of scan can be changed using the rotary channel selector.
! To remove an active channel from scan memory press and hold /MEM and
scan resumes.
! Press and hold /OS/GS for 2 seconds to switch between GS and OS modes.
To deactivate scan, press momentarily.
! When Scan is deactivated the starting channel will be reinstated.
! If scan is deactivated while on hold the hold channel will be reinstated.
! OS Mode is indicated by the absence of the GS icon.
