SQUELCH  
The squelch is used to eliminate any annoying background noise when there  
are no signals present.  
Make sure to first select a channel not in use before setting the  
squelch in your UH075 UHF-CB radio.  
Think of squelch as a gate. Turn [SQ] fully  
Strong Signals  
clockwise. This raises the "Squelch Gate" so high  
that only the very strong signals can get through.  
Medium Signals  
Weak Signals  
Noise  
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.

UT01913ZZ_1 11/21/03 5:50 PM Page 12  
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  
Normal Simplex Operation  
Transmitting on CH 01  
No signal being  
received  
Operation with the aid of a Repeater  
Repeater Station  
CH 01  
CH 31  
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 UH075 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  
UH075 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 UH075 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.  
scan  
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.

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  
UH075 will continue monitoring the Priority Channel for activity
