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

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.

Selective Calling

18

Outline

Selective Calling (Selcall) is a special Sequential Tone Squelch System that allows the
user to receive/transmit calls selectively from/to an individual or group, on a shared
busy channel.

The uh015sx has a Selective Calling system. Exceptional features, like Receiver
Quieting, Tone Squelch Scanning, Tone and Group Calling make the uh015sx superior
to any transceivers in its class.

Receiver Quieting (Tone Squelch)

When activated, it automatically mutes the receiver audio circuit of the radio. It will
stay in this Quiet mode as long as the Selcall tone code (Selcall ID) required to
open the muting circuit is not received.

Call Alarm

When a received code matches to your Selcall ID, an alarm (CA Alert) will be
emitted informing you that a caller is on the channel.

Tone Squelch Scanning

Scans only tone squelched Channels.

Tone Calling

Allows you to selectively call another radio.

Group Calling Capability

Transmits and Responds to Group Calls.

Receiver Quieting

Puts the receiver in the QUIET mode (also known as the Tone Squelch mode). When
activated, the transceiver prevents any unwanted conversations in the channels from
being heard unless the call is specifically directed to you and the Selcall ID required to
open the QUIET condition has been received. Under this condition, the PTT button is
temporarily disabled. If you wish to use the same Channel for normal communication,
simply remove the Channel from QUIET mode.

UNIDEN Model uh015sx UHF CB Radio

Selective Calling

19

To Activate:

1. Select the channel you want to put in ‘QUIET’ mode using the Channel selector.

2. Press and hold /TSQ for 2 seconds. Two beeps are heard and the TSQ
icon appears on the LCD display.

To Deactivate the Quiet Condition:

1. Select the Tone squelched Channel using the Channel Selector.

2. Press and hold /TSQ for 2 seconds. Two beeps are heard and the TSQ
icon disappears from the LCD display.

Call Receiving

While in TSQ condition, when uh015sx receives a code matching your Selcall ID, it will
perform the following operations.

a) Automatically responds to the caller by transmitting Acknowledge Tones.

b) Informs you that a caller is on the Channel by emitting a CALL ALARM (Default

Alarm Setting: four successive beeps in a regular interval for 10 seconds. Refer to
page 32, ‘Alarm Mode’ for other alarm settings) and displays the CAL icon.

c) Flashes the TSQ icon for about 20 seconds allowing you to use the PTT button. If

you are not able to respond within the 20 second period, TSQ icon stops flashing
and ‘QUIET’ mode resumes.

The uh015sx can decode a Selcall call even though not in ‘QUIET’ mode.

Tone Squelch Scanning

If you are using two or more Channels in the TSQ mode, you can monitor all of these
Channels for selective calls by using the TSQ scanning feature.

To use this feature start the TSQ Scan by pressing and holding /TSQ for 2
seconds during Open Scan or Group Scan.

Unlike Normal Scanning, TSQ scans and checks detected signals for Selcall
information. If this information is not found, TSQ Scanning resumes.

When a call is received during TSQ Scanning, uh015sx follows the same response as
when receiving a call on a Tone Squelch Channel.
It differs only in the following ways:

1. If the call is not answered within 20 seconds, TSQ Scanning resumes.

The CAL icon remains on the LCD display.
To look for the Channel where the CALL is received.
a) Cancel TSQ Scanning by pressing .
b) Using the Channel Selector, browse through the TSQ Channels. The CAL

indicator marks the Channel where the Call is received.

2. When answered, TSQ Scanning is automatically deactivated. The Channel is

removed from the QUIET Operating Mode.
To deactivate TSQ Scanning:
a) Press and hold /TSQ for 2 seconds.

The unit returns to Normal Scanning Mode.

b) Press .

The whole scanning operation is cleared.

c) When a Selcall is received, press the PTT button.

The chance of receiving and decoding Selcalls effectively during TSQ
Scanning can be increased in many different ways. You can either
decrease the number of channels to be scanned thus increasing the
scanning speed – or – change some of the Selcall parameters (refer to
‘Selcall Programming’).

Tone Calling

Tone Calling allows you to selectively call other radios.
To do this, the Selcall ID of the radio you are going to call should be in the transmitter’s
Selcall ID memory (refer to '5/6 TX Tone Selcall Programming’ page 21).

To Call:

1. Select the channel that you and your group agreed to use for Selective Calling.

2. Press and hold for 2 seconds.

A beep tone will be heard and the CAL indicator will appear on the LCD display
while the Selcall ID is being transmitted automatically.

An acknowledge tone coming from the called radio will be received if you have
successfully made contact. The acknowledge tone for the uh015sx is a succession of
three low tone beeps.

Group Calling

The uh015sx has the capability to respond to Group Calling and to transmit Group
Calling Codes.

Group Calling allows you to call members of your group simultaneously. However, to
do this, you need to follow a certain format when programming your TX Selcall ID.

TX Selcall ID Format

To call Transmitter SELCALL ID
10 radios [X] [X] [X] [X] [A]
100 radios [X] [X] [X] [A] [A]
1000 radios [X] [X] [A] [A] [A]
10000 radios [X] [A] [A] [A] [A]

where: [X] is a common Selcall ID prefix of your group

- and - [A] is the CCIR Assigned Group Tone Code

Example:

If one group comprises 10 members with Selcall IDs the ID numbers could be as
follows -

Group ID # Individual ID#

[1] [2] [3] [4] [0]
[1] [2] [3] [4] [1]
[1] [2] [3] [4] [2]
[1] [2] [3] [4] [3]

to -

[1] [2] [3] [4] [9]

all in TSQ mode at CH20

If someone transmits [1] [2] [3] [4] [A] on CH20, all of the above units will open their
Tone Squelched Receiver.

Group Calls and ordinary Selcalls can be differentiated in the following manner:

Group Call - Low tone beeps
Ordinary Selcall - High tone beeps

Acknowledge tones will not be received when a Group Call code is
transmitted. If all radios respond, acknowledge tones would only ‘litter’ the
channel with crisscrossing signals.

Tone Period

Tone period is the duration of one tone in a Selcall ID sequence. The setting of this
parameter depends on the type of application. On long distance communications, for
example: where the signal strength of the transmitted information is greatly reduced
and affected by noise, it is advisable to use a longer Tone Period. A long Tone Period
gives the decoder more time and information to check and evaluate the code.

However, be sure that all the radios in your group use the same Tone Period
setting. Otherwise you will not be able to selectively call one another.

The uh015sx allows you to select which Tone Period is best for you. The three most
commonly used tone settings (40,70 or 100 mSec) are available. With the freedom to
change this parameter, you can easily adapt to the existing system in your group
without the inconvenience of having the unit serviced by the dealer.

1. Press and hold then turn power on. Rotate the Channel Selector

until is displayed.

2. Press /ENTER and (factory default setting) will flash and Tone

Period editing is possible.

3. Rotate the Channel Selector to change the Tone Period value.

-or-

Turn the channel selector to go to the next programmable parameter.

Lead-in Delay

Lead-in delay is a Selcall transmission parameter that ‘wakes-up’ and helps the
receiver of the other radio to lock onto the incoming signal. Each time a Selcall ID is
transmitted, the Lead-in Delay attaches itself to the beginning of the code sequence
and causes the transmitter to be on for a longer period prior to the code transmission.
This makes for a stronger communication link between the transmitter and the other
receiver.

One major advantage to having the longer Lead-in Delay is when selectively calling
another radio via a repeater station. A longer Lead-in Delay helps to stabilise both the
communication link from your radio to the repeater station and from the repeater
station to the other radio.

Lead-in Tone

The Lead-in Tone, when programmed, ‘rides’ on the Lead-in Delay.
Hence, when transmitting a Selcall ID, a continuous tone will be heard for the duration
of the Lead-in Delay.

The main purpose of the Lead-in Tone is to increase the probability of contact between
your unit and another radio when TSQ Scanning.

1. Press and hold then turn power on.
Rotate the Channel Selector until is displayed.

Tone _ 1 is the factory default setting of the uh015sx for Lead-in Tone.

Alarm Mode

When a received code matches to your receiver Selcall ID and you selected the Call
Alarm Auto Mode the Unit will:

a. Transmit an Acknowledge tone to the Caller.
b. Emit CALL Alarm for 10 seconds only.
c. Resume Quiet condition automatically after 20 seconds if the call is not answered.
d. The Unit will start decoding again when the 20 second period elapsed and the call

remained unanswered.

Call Alarm Continue Mode

a. The Unit will transmit an Acknowledge Tone to the Caller.
b. Initially an alarm of four successive beeps is emitted for 20 seconds and then two

successive beeps every four seconds continuously unless answered.
c. The Quiet Condition is never resumed.
d. The Unit continues to check if incoming codes have your Receiver Selcall ID even

though the Quiet Condition is already opened.

When detected, it will send an acknowledge Tone to the caller and then resets the

Call Alarm.
