TO TRANSMIT AND RECEIVE  
The UH-042XR uses the 40 UHF-CB Channels. For your reference a list of the  
available channels and corresponding frequencies is printed at the end of this  
manual.

2. Before you transmit, listen for  
activity on the selected channel.  
3. When the channel is clear, press and

SCANNING  
The UH-042XR 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 CH01 when switched on.  
2. Press [SCAN] and scanning starts.  
Scan icon flashes during scanning.

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 pages 10.

Example: CH40 becomes active  
If the received signal ceases, 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-042XR will stay on that  
active channel. If no other channels are active, the UH-042XR will reinstate the  
starting channel.  
2. Pressing [OS/GS] will switch to Group Scanning.

To use GS Mode Scanning, press the [OS/GS]  
key. GS icon appears on the display.

Note:  
1. If SCAN is deactivated while it is tuned to an  
active channel, the UH-042XR will stay on that  
active channel. If none of the channels are  
active, the UH-042XR 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 [OS/GS] will switch to Open Scanning.

PRIORITY CHANNEL  
The Priority Channel feature allows user to monitor one of 40 channels in the  
UH-042XR, 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)

CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS)  
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.  
Programming CTCSS Code  
1. Select a desired channel to be used with CTCSS.  
2. Press and hold [CTCSS] for 1.5 secs. CTCSS code

3. Press [] or [] to select the desired CTCSS code.  
4. Press [CTCSS] to save the selected code.

CTCSS Scan Operation  
1. Press [SCAN] to start scanning (GS or OS) mode.  
2. During scanning if a signal is sensed on a CTCSS CH, the  
UH-042XR 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.

microphone of the VOX headset (not supplied) without pressing the PTT switch.  
NOTE: VOX feature will not work without the Headset Microphone.  
Built in [PTT] of UH-042XR is temporarily disabled, however accidental  
pressing of [PTT] will cause the unit to transmit briefly.  
To activate VOX  
1. Turn the UH-042XR OFF.  
2. Press and hold [VOX] while turning the radio ON. “VOX” appears on the  
bottom left of the display.

4. UH-042XR returns to PTT operation.  
Note: Turning ON the radio without removing the VOX headset will cause the unit  
to transmit continuously.  
DROP-OUT DELAY  
While scanning, the UH-042XR 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.  
POWER SAVE  
Battery Save feature extends the battery life by switching the receiver circuit  
power ON and OFF. This feature automatically activates during stand by mode  
(RX mode without signal). It turns OFF automatically when a signal is present,  
and activates again after channel inactivity.

BUSY CHANNEL LOCK-OUT(BCL)  
This feature prevents accidental transmission on a busy channel.  
This is recommended on channels where CTCSS is being used. If the channel is  
activeand the signal is coming from a non or different CTCSS code user the  
BCL feature will prevent you from transmitting.  
To activate BCL  
Press and hold [BCL] for 1.5 secs until “BCL”
