BATTERY CHARGE INDICATOR  
When charging, the CHG icon appears on the  
display.  
Note :  
1. Transmit Operation is disabled when  
UH-052XR is being charged.  
2. A single tone is emitted by the radio and CHG is displayed to indicate  
that it has started charging.  
3. When the battery is totally empty, CHG icon blinks or the display may  
totally disappear, the radio will be unable to receive any signal and all  
the keys are disabled. In this case, it is best to switch OFF the radio to  
help facilitate charging.  
UH-052XR will return to normal operation once enough power level is  
established.  
Note: If you are unable to charge a fully discharged battery, switch OFF the  
radio to avoid further discharging. When possible, recharge the  
batteries for the recommended time period.

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 UH-052XR 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 UH-052XR 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 Duplex Operating Mode table on the last page.

TO OPERATE UH-052XR IN DUPLEX MODE  
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. UH-052XR will return to simplex  
operation.  
SCANNING  
The UH-052XR has two types of scanning; Open Scanning (OS) and  
Group Scanning (GS), giving you flexibility and allowing you to use the  
radio more effectively.  
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 [SCAN] and scanning starts.  
Scan icon flashes during scanning  
CTCSS  
BCL  
VOX  
OS/GS  
1. 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.  
Note: The factory has preprogrammed all the 40 UHF channels into the  
Open Scan channel memory. However, you can change or customise  
the channels by following the steps on programming Scan Channels  
on page 12.  
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 [MEM] momentarily. Scanning resumes.  
To deactivate SCAN, press the [SCAN] or [PTT].

Note:  
1. If SCAN is deactivated while in an active channel, the UH-052XR will stay  
on that active channel. If no other channels are active, the UH-052XR  
will reinstate the starting channel.  
2. Pressing [CTCSS] for 1.5 Secs. Will deactivate Open Scanning and  
activate CTCSS Scanning.  
3. Pressing [OS/GS] will switch to Group Scanning.  
2. 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.

VOX  
OS/GS  
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-052XR  
will continue monitoring the Priority Channel for activity while listening to  
the active one.  
To deactivate SCAN, press the [SCAN]  
or [PTT].

052XR will reinstate the Priority channel.  
2. 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.  
3. Pressing [CTCSS] for 1.5 Secs. Will deactivate Group Scanning and  
activate CTCSS Scanning.  
4. Pressing [OS/GS] will switch to Open Scanning.

PRIORITY CHANNEL  
The Priority Channel feature allows user to monitor one of 40 channels  
in the UH-052XR, monitoring it every 1.5secs during Group Scanning.  
Choosing a Priority Channel  
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)  
or  
b. press [], to select a lower channel  
DROP-OUT DELAY  
While scanning, the UH-052XR 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.  
ADVANCED FEATURES  
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.  
NOTE : Uniden discourages the use of CTCSS feature until the Australian  
Communications Authority (ACA) grants the use of CTCSS on CB  
frequencies.

3. During scanning and a signal is sensed on a CTCSS CH, the  
UH-052XR stops for about 400msecs (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.  
On the example below only radio 1 and 9 can communicate or hear each  
other because they are using the same or common CTCSS code.
