ROGER BEEP
Roger Beep is a BEEP that is sent to notify the end of transmission (both PTT
and VOX transmission.) Roger Beep can be heard through the speaker when
Key Beep is on. Roger Beep is transmitted even if key beep is turned off.
However Roger Beep will not be heard from the speaker.
To turn OFF Roger Beep: Press and hold while turning on the radio.
To turn ON Roger Beep: Press and hold while turning on the radio.
SELECTING CHANNEL
Press or to select the desired channel.
If you press and hold the or ,
channel number will scroll rapidly.

SQUELCH
The squelch is used to eliminate any annoying background noise when there
are no signals present.
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.
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.

Make sure to first select a channel not in use before setting the
squelch in your UH076SX UHF-CB radio.

TO TRANSMIT AND RECEIVE
The UH076SX uses the 40 UHF-CB Channels. For your reference a list of the
available channels and corresponding frequencies is printed on page 20.
1. The maximum RF transmit power of UH076SX is 5 Watts.
2. Before you transmit, listen for activity on the
selected channel.
3. When the channel is clear, press and hold the
to transmit. TX appears on the LCD.
4. When you have finished speaking, release the
and listen for a response. TX indicator
then disappears on the LCD.
The display shows BUSY when a transmission
is being received by your radio.
Hold the radio with microphone approximately
five cms in front of your mouth with the
antenna at approximately 45* angle away from
your head. Speak in a clear, normal
conversational voice.
To switch to low power, press . LOW
appears on the LCD.
To switch back to higher power, press
again. LOW indicator disappears from the LCD.

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.
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 is designed with duplex capability on Channels 1 to 8. When any
of these channels are set to operate in duplex mode during transmission, the
UH076SX 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. CH02 is on Duplex Mode
- will Receive on CH02 but Transmit on CH32, etc….
Refer to UHF Channel & Frequencies table on page 20.

TO OPERATE UH076SX IN DUPLEX MODE
Eg. CH01 is being used in your area for repeater use.
SCANNING
The UH076SX 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;
1. Assuming the unit is on CH17 when switched on.
2. Press and scanning starts. SCAN icon flashes during scanning.
Open Scan (OS) Mode (the absence of GS icon indicates that the unit is on
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.
The factory has preprogrammed all the 40 UHF 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 15.
Example: CH40 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 momentarily. Scanning resumes.
To deactivate SCAN, press or .
Check with your local retailer for available repeaters.
Press momentarily. The DUP icon appears.
Press again to deactivate the duplex operation.
UH076SX will return to simplex operation.

Group Scan (GS) Mode
Allows you to monitor a Priority Channel while scanning.
To use GS Mode Scanning, press the key. .
GS icon appears on the
display.
GS Scanning checks the Priority channel activity regularly.
If SCAN is deactivated while in an active channel, the UH076SX will
stay on that active channel. If no other channels are active, the
UH076SX will reinstate the starting channel.
If SCAN is deactivated while it is turned to an active channel, the
UH076SX will stay on that active channel. If none of the channels are
active, the UH076SX will reinstate the Priority channel.
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.
If scanning stops on a channel which is not a Priority Channel the
UH076SX will continue monitoring the Priority Channel for activity
while listening to the active one.
To deactivate SCAN, press the or .

2. Select the channel you want to store by pressing or .
3. Press and hold for 1.5 secs. to store. MEM icon appears and two

PRIORITY CHANNEL
The Priority Channel feature allows user to monitor one of 40 channels in the
UH076SX, monitoring it every 1.5 secs. during Group Scanning.
Choosing a Priority Channel
DROP-OUT DELAY
While scanning, the UH076SX stops at a busy channel and receives a
transmission. When the received signal is over, the unit will wait for 3 seconds
for the return of the signal, otherwise, the radio resumes scanning.
The starting channel, when Group Scanning is
initiated, is always the Priority Channel. To change
the priority channel setting while scanning, (eg. PRI
Channel is CH17 (476.825 MHz ));
a. press , to select a higher channel (scanning
pauses).

ADVANCED FEATURES
VOX
MBuilt-in Voice Activated Circuit (VOX) feature enables the user to
transmit automatically by speaking on the microphone of the VOX headset
(not supplied) without pressing the PTT switch.
CTCSS (Continuous Tone Coded Squelch System)
CTCSS is a feature that allows a group to talk to each other without hearing
other users on the same channel.
Programming CTCSS Code
1. Select a desired channel to be used with CTCSS.
2. Press and hold for 1.5 secs. CTCSS icon blinks.
3. Press or to select the desired CTCSS code.
4. Press to save the selected code. CTCSS icon stops blinking.
The UH076SX will return to standby mode after 10 secs. of no
activity. CTCSS code can be programmed on every channel. There
are 38 available CTCSS tone per channel.
CTCSS Scan Operation
1. Press to start scanning (GS or OS) mode.
2. Press and hold to change to CTCSS scan mode.
3. When a signal is sensed on a CTCSS CH, the UH076SX stops for about
400 msecs (decode time) to decode the CTCSS code. If there is no code or the
receive code does not match the one programmed on the unit, the unit
resumes scanning.
Channels 5 and 35 are used for emergency channels. CTCSS will
not operate on these channels.
