Operation
UNIDEN UH076SX-NB Handheld UHF-CB Transceiver
Squelch
The squelch is used to eliminate any annoying background noise when
there are no signals present.
NOTE
Make sure to rst select a channel not in use before setting
the squelch in your UH076SX-NB UHF-CB radio.
Think of squelch as a gate. Turn [SQ] fully
clockwise. This raises the “Squelch Gate” so high
that only the very strong signals can get through.
Turn [SQ] fully counter clockwise until you hear a
hiss. This opens the “Squelch Gate” so that
everything gets through noise, weak signal, and
strong signals.
To set the “Squelch Gate” to the desired level, turn
[SQ] counter-clockwise until you hear noise. Then
turn the [SQ] clockwise just until the noise
stopped. Now only the desired signal can get
through.
NOTE
If an incoming signal is very weak there is a possibility that
you will have a choppy or broken reception, due to the
sensitivity of the squelch. In this case, simply rotate the
[SQ] clockwise until the weak signal is heard clearly.

is being received by your radio.

18
Operation
UNIDEN UH076SX-NB Handheld UHF-CB Transceiver
Using a Repeater Channel
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 (i.e.
a Tall Building) that partially blocks your transmitted signal, the possibility
of the other radio receiving the signal is very slim. Valleys, 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
With Duplex operation, the signal coming from your radio is received
by the Repeater station and then re-transmitted at the same time on
another channel.
Your UH076SX-NB is designed with duplex capability on Channels 1 to 8
and Channels 41 to 48. When any of these channels are set to operate in
duplex mode during transmission, the UH076SX-NB automatically sends
the signal at a frequency 30 channels above the original in order to access
the repeater station. After transmitting, the radio reverts back to its original
operating frequency.
For example:
1. CH01 is on Duplex Mode - will receive on CH01 but Transmit on CH31
2. CH41 is on Duplex Mode - will receive on CH41 but Transmit on CH71,
etc... Refer to UHF-CB Channel & Frequencies table on p.27 - p.28.

19
UNIDEN UH076SX-NB Handheld UHF-CB Transceiver
Operation
To Operate UH076SX-NB in Duplex Mode
Only channels 01 - 08 and 41 - 48 are available for Duplex.
Eg. CH01 is being used in your area for repeater use.
Press dup momentarily. The DUP icon appears.
Press dup again to deactivate the duplex operation.
UH076SX-NB will return to simplex operation.
NOTE
Check with your local retailer for available repeaters.
Scanning
The UH076SX-NB has two types of scanning; Open Scanning (OS)
and Group Scanning (GS). Scanning allows you to search for active
channels programmed in the OS or GS memory.
To initiate scanning;
Press scan and scanning starts. SCAN icon ashes during scanning.
Open Scan (OS) Mode
The absence of GS icon indicates that the unit is in OS mode. Allows
continuous scanning of channels stored in the Open Scan (OS) memory.
If an active channel is found, scanning will stop on that channel.
NOTE
The factory has preprogrammed all the UHF-CB channels
into the Open Scan channel memory. However, you can
change or customize the channels by following the steps on
programming Scan Channels on page 21.
Example: CH80 becomes active
If the received signal cease, the unit will wait for at least 3 seconds for
the signal to return, otherwise scanning resumes.
To skip the active channel, press mem momentarily. Scanning resumes.
To deactivate SCAN, press scan or PTT .

20
Operation
UNIDEN UH076SX-NB Handheld UHF-CB Transceiver
NOTE
If SCAN is deactivated while in an active channel, the
UH076SX-NB will stay on that active channel. If no other
channels are active, the UH076SX-NB will reinstate the
starting channel.
Group Scan (GS) Mode
Allows you to monitor a Priority Channel while scanning.
To use GS Mode Scanning, press the os/gs key. GS icon appears on
the display.
GS Scanning checks the Priority channel activity regularly.
NOTE
If GS Scanning is initiated when there are no channels
programmed in GS memory, an error tone will be heard and
scanning will not start.
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.
NOTE
If scanning stops on a channel which is not a Priority
Channel the UH076SX-NB will continue monitoring the
Priority Channel for activity while listening to the active one.
To deactivate SCAN, press scan or PTT .
NOTE
If SCAN is deactivated while it is turned to an active
channel, the UH076SX-NB will stay on that active channel.
If none of the channels are active, the UH076SX-NB will
reinstate the Priority channel.
