Operation

Setting the Squelch

1. To turn the unit ON, rotate VOLUME clockwise.
Adjust volume to a comfortable level.

Note: You must select a channel which is not in use before setting the SQUELCH

control on your radio.

2. Think of the Squelch control as a gate. If you turn SQUELCH fully clockwise it
raises the "Squelch Gate" so high that no signals get through.

Using Repeater Channels

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 (Le. valley) that partially blocks

your transmitted signal, the probability of another radio receiving the signal is very
slim. Valleys, tall buildings, metallic structures, ... etc. tend to act as a screen between

radios.

the aid of a repeater Station

Operation with the aid of a repeater

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".

YourUH-100is designed withthe capabilityto access and use repeater stations.
Channels 01 through 08 have the option to operate in Duplex Mode. When any of

these channels are set to operate in duplex mode during transmission, the UH-100
automatically sends the signal at a frequency 30 channels above the original. After
transmitting, the radio reverts back to its originaloperating frequency.

For example,

CH01on DuplexMode willReceive on CH01 but Transmit on CH31

CH02on Duplex ModewillReceive on CH 02 but Transmit on CH32 etc....

Ifyou transmit on CH01 Duplex mode, you are actually transmitting on CH31, the
repeater station down-converts your signal and retransmits on CH01.

To operate UH-100in Duplex Mode,

ego CH01 is being used in your area for

repeater use.

Scanning

The UH-100 has a scanning feature that allows you to search for active channels

automatically.

Furthermore, the UH-100 is designed to have two types of scanning; Open Scanning
(OS) and Group Scanning (GS), to give you flexibility and allow you to use the radio

more effectively.

To initiate scanning.

2. Group Scan (GS) Mode

Allows youto monitor a Priority Channelwhile scanning.
To use GS Mode Scanning, press the OS I GS key.

GS icon appears on the display. OS Mode is indicated
by the absence of the GS icon.

GS Scanning checks the Priority channel activity
regularly.

If the Priority channel becomes active the radio will stay
on that channel for as long as the signal is present. If
the received signal ceases, Priority scanning continues

after 3 seconds.

If scanning stops on a channel which is not a Priority
Channel, UH-100 will continue monitoring the Priority
Channel for activity while listening to the active one.

Channel Seeking Operation

Unlike normal scanning, CHANNEL SEEK is used more often when checking for active

channels.

If a signal is detected, while seeking, the UH-100 will tune to that signal for 4 seconds

only and then resumes Seeking Operation.
Changing from SCAN to SEEK Mode operation.

1. Firstly, activate SCAN mode.

2. Press and hold SCN until a "beep" is heard. The SCN
icon starts to flash.

3. If an active channel is detected the UH-100 will stop on
that channel for 4 seconds. (eg. CH17)

4. After 4 seconds, the UH-100 will start seeking again
for active channels.

5. If you find the channel interesting, simply press either
the PTT switch or the SCN key to stop the operation

before the 4 second timer elapses.

When SCN is pressed again SEEK is still the mode of operation.

To change back to SCAN, while SEEKING. press and hold
SCN until a beep is heard. The SCN icon stops flashing.

Voice Scrambler

UH-100 has a built-in scrambler / de-scrambler circuit.

The Voice Scrambler feature prevents users, without the necessary descrambler
equipment, "understanding" your conversation. This feature is NOT operable on CH01

through CH08, CH31 through CH38, and CH11, and will only work between units

with the voice scrambler feature compatible with the Uniden UH-100.

Selective Calling

When you listen to UHF CB you will hear all the conversations going on, which can
become annoying at times. Ideally you need a system that alerts you when the signal
is from someone you wish to communicate with.

You want your radio to be SELECTIVE about the people you talk to!
That's what the Uniden UH-100 offers, with SELECTIVE CALLING, commonly known

as SELCALL. It lets you know that the people you want to talk to are calling.
To achieve this each radio must have a SELCALL ID.

This SELCALL ID acts as a "Phone Number" and your radio as a "Mobile Phone".

Everybody in your group must have a different "Phone Number" that only your group
members should know. If one of your members dials your "Phone Number", when
reached successfully, your "Mobile Phone" of course will "Ring", and your caller will
hear a "Ringing Tone".

This "Ring" is actually a CALL Alarm, and the "Ringing Tone" is an Acknowledgment
Tone. Any user tuned to your UHF CB channel will hear the conversation.

Note: You only give your Selcall code to people who you want to be able to get in

touch with. Likewise you need to know their Selcall codes to be able to contact
them. Other users in your SELCALL family may not be using Uniden radios, the

Uniden UH-100 can be programmed to have full compatibility with other brands.

Please read the selcall advance programing section of this manual for guidance.

The Audio scrambler and the SELCALL functions cannot be operated
simultaneously.

Group Calling

Most Selcall users will have several members in their group. It is possible that everyone
in the group needs to be alerted at the same time, for example when an emergency
situation occurs. Calling them one by one can be inconvenient and time consuming. It

is possible to create a special code that will be recognized by every radio in the group

when transmitted. Your UH-100 incorporates this feature known as Group Calling.
The UH-100 has the capability of being owner programmed to Group Call within groups

of 2 to 10,11 to 100,101 to 1000 or 1001 to 10000 radios.
While you were setting SelcalllO numbers to be sent, you may have noticed the letter

"A" appeared on the LCO from time to time. This letter has a special application. When
added in your code to be transmitted, it tells the UH-100 that the call is a Group Call in

nature. Note that you have to follow a special format to make a Group Call.

To make a Group Call work all members of the group must have Selcall ID's in a

numerical sequence. e.g. group of 10 users may have the following SelcalllO's:

23450
23451
23452
23453
23454

23455
23456
23457
23458
23459

To be able to Group Call all the other 9 radios in your group of

10 you would need to transmit the code 2345A.

f13 GAL

SRF 1

~:JI{SR

'-' ,-,

IL'

ALL radios with 2345 as the first 4 numbers of their ID Code will be alerted.

Using the first four digits followed by "A" is suitable for calling groups of 2 to 10 radios
as shown above.

The first 3 digits followed by "AA" is for 11 to 100 radios. (eg 234AA)
The first 2 digits followed by "AAA" is for 101 to 1000 radios. (eg 23AAA)

The first digit followed by "A" is for 101 to 10000 radios. (eg 2AAAA)
You can still call any of the individual members of your group, without calling all the

others, by programming the individual's SelcalllO into a separate memory location.
e.g. You have your group call code (2345A) in memory location 5. You want to be able
to call unit 23453 outside the group so you store 23453 in memory location 3.

The UH-100 differentiates group calls and individual calls by emitting different alarm
beeps.

For Group Calls the alarm beepwill be a Iow tone and for individual tone calls the beep
will be a high tone.

Note: When you transmit a Group Call you will not receive acknowledgment tones

from the other radios as you nonnally do with individual tone calls.

28

Tone squelch (Receiver Quieting)

Receiver Quieting, or Tone Squelch (TSQ), is actually SELCALL in action. The UH-
100 receiver is muted and you cannot hear any signals until the mute is disengaged by
reception of your Selcall code.

Refer to page 8 for explanation of how the squelch system works.

The Squelch discussed previously "screens" the received signal level, however in tone
squelch mode, the squelch monitors the signal for your ID.

1. The Tone Squelch Control acts as an electronic lock. Activating the Tone squelch
closes this lock.

Regardless of how strong the received signal is, if it does not have the required
"electronic key" the gate will remain closed.

NoKey

~@

Received Signal

2. If the received signal contains the required key (which is your Radio ID), this
electronic lock will open.

The muting circuit is then deactivated on your radio and advises you that a call has
been received.

Press the SCRAMBLElTSQ button for about 1.5 seconds. Two beeps are heard

and the TSQ indicator disappears from the display.

Receiving Calls when in Quiet Mode

The UH-100 will respond in the same way in quiet mode as when it is called while in

normal mode.

When the call is left unanswered, however, the radio automatically resumes the quiet
condition. (The auto - quiet mode function can be switched ON or OFF, please refer to
the Selcall Advance Programming section on page 32)

30

Tone Squelch Scanning

You may wish to limit your scanning activities so the UH-100 will only scan the channels
you have pre-arranged to use with your SELCALL family. These are the channels you

have programmed as TSQ or quiet mode.

Tone Squelch Scanning applies this function.
To activate this feature firstly initiate SCAN.

SELCALL Advance Programming

The Sundowner UH-1 00 radio is fully user programmable. It gives you the freedom to
select your own radio ID, configure the radio's response when a call is received, change

SELCALL parameters for compatibility with other UHF Radio brands, plus much more.

Please read the following procedure carefully to understand the full SELCALL capability

of this radio. This will enable you to utilize the SELCALL to maximum effect.
Since the following items are NOT frequently changed, and are characterized as highly

significant, a special accessing procedure has been developed to prevent accidental
changes or programming.

To access the SELCALL Parameter Programming mode.

First, switch OFF the radio.

Press and hold the OS/GS key and switch the radio ON simultaneously.

Tone Period Programming

Tone Period is the duration of one tone in a SElCALL ID sequence. The setting of this
parameter depends on the application. On long distance communications, 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.

Important Note: Ensure all radios in your group use the same tone period setting,

otherwise, you will not be able to selectively call one another.
To change the Tone Period setting.
From the main menu, using the... or T key, go to the Tone Period Programming Menu.

Lead -In Delay Programming

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.

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

station to the other radio.

To change the Lead - In Delay setting.
From the main menu, using the.. or ~ key, go to the Lead - in Delay Programming

Menu. (If you have never changed the Lead

-In delay duration, the default setting is

Lead -In Tone Programming

The Lead-In Tone when programmed, rides on the "Lead in Delay". When transmitting

a SelcalllD a continuous tone will be heard for the duration of the Lead In Delay.

The mainfunction of the Lead - InTone is to increase the probability of contact between

radios when Tone Squelch Scanning.
Unlike normal scanning, TSQ Scanning monitors the detected carrier for the presence

of Lead -Intone. Without it, TSQ scanning resumes.

If a Lead - In Tone is present the UH-100 will lock onto that signal and wait for the
SELCALL ID.

You can program the UH-100 to lock onto a particular Lead

-In Tone. This feature

enables the radio to immediately recognize whether the signal present is intended for
your group.

i.e. If you are using Tone 1, your radio during TSQ scanning will lock only onto signal

with Tone 1 as its Lead -In tone.

Note: Should you wish your radio to lock onto any transmission regardless of Lead-In

tone type present select "Tone - - ".

Care and Maintenance

Notice

If the UH-100 has been subjected to extreme high temperature (above 60°C) for a
prolonged period of time, blackening of the Liquid Crystal Display (LCD) may occur.
This is not a fault. Normal LCD operation resumes when the temperature stabilizes
back to standard operating conditions (0 to 55°C).

Preventive Maintenance

The following system checks should be made every six to twelve months:

1. Check the Standing Wave Ratio (SWR).

2. Inspect the tightness of all electrical connections.

3. Inspect the antenna coaxial cable for wear or breaks on the shielding.

4. Inspect the tightness of all screws and other mounting hardware.

Troubleshooting

Should the unit malfunction or perform poorly, follow the procedures indicated below:

1. If the transceiver is completely inoperative...
* Check the power cord and fuse.

2. If there is trouble with receiving...
* Check the VOLUME control setting.
* Be surethe SQUELCHis adjusted properly.Possiblythe radiois over-squelched.

* Check that the radio is in an operational mode.

3. 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.

Memory Backup

A built-in capacitor protects the channels stored in the SUNDOWNER UH-100 memory
for up to 2 weeks after the DC power cable is disconnected.
