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

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

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.

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.

To switch to low power, press 1/5w . LOW
appears on the LCD.

selected channel.
3. When the channel is clear, press and hold the
PTT
to transmit. TX appears on the LCD.
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.

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 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.

Check with your local retailer for available repeaters.
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.

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.

2. Press and hold ctcss 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.
VOX
