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.

➤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.
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.

SQUELCH
The squelch is used to eliminate any annoying background noise when
there are no signals present.
Think of squelch as a gate. Turn [SQ] fully
clockwise. This raises the ”Squelch Gate” so
high that only the very strong signals can get
through.
(Make sure to first select a channel not in use
before setting the squelch in your UH-050XR
UHF-CB radio.)
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.
Note: 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.

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.

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
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].
OS/GS
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.
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].
Note:
1. If SCAN is deactivated while it is tuned to
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.
