2. Use a coin to turn the screw that
connects the battery pack to the
UH-050XR. Be sure the battery
pack fits tightly against the
UH-050XR body.
CHARGING THE BATTERY PACK

BATTERY CHARGE INDICATOR
When charging, the CHG icon appears on the
display.
Note :
1. Transmit Operation is disabled when
UH-050XR 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-050XR 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.
5
OPERATION
➤ When you press any key (except PTT), a short tone sounds.
➤ See the Controls and Indicators page at the back of this operating
guide for button and key operations.
POWER ON/OFF
To turn the unit ON, rotate the [ON/OFF VOL]
clockwise until a “click” is heard. A channel

number and battery level should appear on
the display.
To turn the unit OFF, rotate the [ON/OFF VOL]
knob counter-clockwise until a “click” is
heard. The display will disappear.
OFF
VOLUME
Rotate the [ON/OFF VOL] knob clockwise or
counter-clockwise to adjust speaker volume to desired listening level.
Note: If no sound is heard, temporarily unmute the radio by briefly
rotating the [SQ] until you hear the receiver’s background noise.
Rotate [ON/OFF VOL] to desired level. When finished, rotate [SQ]
until noise disappears.
SELECTING CHANNEL

TO TRANSMIT AND RECEIVE
The UH-050XR 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.
1. The maximum RF transmit power of
UH-050XR is 5 watts.
To switch to low power, press the
[1/5W]. LOW appears on the LCD.
OS/GS
To switch back to higher power, press
the [1/5W] again. LOW indicator
DUP
LOCK
disappears from the LCD.
2. Before you transmit, listen for
activity on the selected channel.
3. When the channel is clear, press
and hold the [PTT] to transmit.
TX appears on the LCD.
OS/GS
PTT
switch
DUP
LOCK
Hold the radio with microphone approximately two inches in front of your
mouth with the antenna at approximately 45˚ angle away from your head.
Speak in a clear, normal conversational voice.
4. When you have finished speaking, release the [PTT] 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.
8
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-050XR 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-050XR 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.
9
TO OPERATE UH-050XR 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-050XR will return to simplex
operation.
SCANNING
The UH-050XR 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
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].
10
Note:
1. If SCAN is deactivated while in an active channel, the UH-050XR will stay
on that active channel. If no other channels are active, the UH-050XR
will reinstate the starting channel.
2. 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.
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-050XR
will continue monitoring the Priority Channel for activity while listening to
the active one.
To deactivate SCAN, press the [SCAN]
or [PTT].
OS/GS
Note:
1. If SCAN is deactivated while it is tuned to
DUP
LOCK
an active channel, the UH-050XR will
stay on that active channel. If none of the channels are active, the UH-
050XR 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.
11
Programming Scan Channels
1. Select which Scanning Mode you wish
to use on the channel
OS or GS Mode
OS/GS
LOCK
Note: OS is indicated by the absence of
the GS icon

2. Select the channel you want to store
by pressing [➤] or [➤]
3. Press and hold [MEM] for 1.5 secs. to
store. MEM icon appears and two
successive beeps are heard.

once more. Two successive beeps are
heard and the MEM icon disappears.
DUP
LOCK
PRIORITY CHANNEL
The Priority Channel feature allows user to monitor one of 40 channels
in the UH-050XR, 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-050XR 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.
12
➤ 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). A flashing
icon will appear on
the display when the battery save feature is ON. It turns OFF
automatically when a signal is present, and activates again 3secs after
channel inactivity.
➤ BACK LIGHTING
The Liquid Crystal Display (LCD) and function keys are backlit for easy
viewing at night or in low light situations. The back lighting automatically
switches ON every time a key (except PTT) is pressed. It turns OFF 5secs
after the last key is pressed.
➤ KEYPAD LOCK
To prevent accidental entries, you can
