UNIDEN UH5040R UHF CB Transceiver
Preventive Maintenance
The following system checks should be made every six to twelve months:
• Check the Standing Wave Ratio (SWR).
• Inspect the tightness of all electrical connections.
• Inspect the antenna coaxial cable for wear or breaks on the shielding.
• Inspect the tightness of all screws and other mounting hardware.
Troubleshooting
Should the unit malfunction or perform poorly, follow these procedures:
If the transceiver is completely inoperative: Check the power cord and fuse.
If there is trouble with receiving: Check the VOLUME control setting. Be sure the
SQUELCH is adjusted properly. Possibly the radio is over-squelched.
If there is trouble with transmitting: Check that the transmission line (coaxial cable)
is securely connected to the ANTENNA connector. Check that the antenna is fully
extended for proper operation. Check that all transmission line (coaxial cable)
connections are secure and free of corrosion.
NOTE
Blackening may occur on the Liquid Crystal Display if the UHF CB
Radio has been subjected to extreme high temperature (above
60°C). This is not a fault. Normal LCD operation resumes when the
temperature stabilizes back to standard operating condition (0-55°C).

The Microphone Hanger comes in two parts. How and where you mount the MIC
hanger will determine which parts to use.
Conventional Mounting with Screws
Use the front part of the MIC Hanger only.
Locate a suitable mounting position and mark
and drill two 3mm holes.
Fix the MIC Hanger into place with screws.
Conventional Mounting with Double Sided Tape (not supplied)
High quality Double-Sided tape can be found at good retail stores.
Secure the front and back pieces of the MIC Hanger using the supplied binding screws.
Locate a suitable mounting position.

Mounting the Mic Hanger

Setting the Squelch
Turn the outer ring of the control to adjust the Squelch.
NOTE
You must select a channel which is not in use before setting the SQUELCH
control. (see below for “Selecting a Channel”).
UH5040R
Turn on the Power and set the Volume
Turn the unit ON by rotating the volume control clockwise. Set the volume to a desired
level.
UH5040R

UNIDEN UH5040R UHF CB Transceiver
Operation
Think of the squelch
control as a gate. If
you turn Squelch fully
clockwise it raises the
‘Squelch gate’ so high
that no signals get
through.
If you turn the Squelch
fully counterclockwise
it lowers the ‘Squelch
Gate’ to the extent that
all signals get through
- weak, medium and
strong signals and
noise.
To set the ‘Squelch
Gate’ to the desired
level, turn the squelch
knob counterclockwise
until you hear noise.
Then carefully turn the
Squelch knob clockwise
until the noise fades.
Now only strong signals
get through.

Selecting a Channel
Turn the Rotary Channel Selector to select the desired channel.
NOTE
For your reference a list of the available channels, corresponding
frequencies and guidelines for their use is printed on page 20. For
Australia, Channels 05 and 35 are
reserved for Emergency Calls.

Operation
Set the LCD Dimmer
Press [DIM] to set the LCD backlight dimmer between high and low.

Transmitting
The UH5040R uses the 80 UHF-CB Channels For
your reference a list of the available channels,
corresponding frequencies and guidelines for
their use and selection is printed on page 20. For
Australia, Channels 05 and 35 are reserved for
Emergency Calls.
Select the desired channel. Press the microphone’s PTT
button and speak normally into the microphone. Hold it
approx. 7cm from your mouth. Release the PTT button to
end the transmission and listen for a reply.
Call Function
Press the microphone Call Button. A two second ringing tone will be transmitted. You
may select from 5 types of tones (see p.18).
Current regulations require calling tones to be restricted to one transmission per
minute. If a second transmission is attempted within one minute then an error
tone will sound.

Standard Operation without the aid of a Repeater station.
Operation with the aid of a Repeater Repeater Station (Duplex).
The signal coming from your radio is received by the Repeater Station and the re-
transmitted at the same time on another channel. This operation is called “Duplexing”.
For example,
CH01 on Duplex Mode will Receive on CH01 but Transmit on CH31
CH02 on Duplex Mode will Receive on CH02 but Transmit on CH32 etc...
If you transmit on CH01 Duplex mode, you are actually transmitting on CH31 the
repeater station down-converts your signal and retransmits on CH01.
14
UNIDEN UH5040R UHF CB Transceiver
Operation
Using Repeater Channels
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 that partially blocks your
transmitted signal, the probability of another radio receiving the signal is very slim.
Hills, tall buildings, metallic structures,...etc tend to act as a screen between radios.

Operating the UH5040R in Duplex Mode
For this example we are adopting CH01 as the channel being used in your area for
repeater use.
Press [DUP] to switch Duplex On. If Duplex is not required - press [DUP] again to
switch Duplex off. Only channels 01-08 and channels 41-48 are available for Duplex.
Scanning
The UH5040R has a scanning feature that allows you to search for active channels
automatically.
Furthermore, the UH5040R is designed to have two types of scanning; Open Scanning

more effectively. Press [SCAN] and Scanning starts. The SCAN icon appears. The
scan direction can be changed at any time by rotating the channel selector left or right.
NOTE
Check with your local Retailer for information on available
repeaters.

UNIDEN UH5040R UHF CB Transceiver
Operation

Open Scan (OS) Mode
Allows continuous scanning of all selected channels.
If an active channel is found, scanning will stop on that channel.
If the received signal ceases, the unit will wait 3 seconds for the signal to return,
otherwise scanning resumes.
To skip the active channel, press [MEM] momentarily. Scanning resumes. To deactivate
SCAN, press [SCAN] or the PTT button on the microphone.
NOTE
If SCAN is deactivated while on an active channel, the UH5040R will
stay on that active channel. If no channels are active, the UH5040R will
reinstate the starting channel.
NOTE
OS Mode is indicated by the absence of the GS icon.
16
UNIDEN UH5040R UHF CB Transceiver
Operation

Group Scan (GS) Mode
Allows you to monitor a Priority (Instant) Channel while scanning (Instant Priority
channel see p.20).
To use GS Mode Scanning, press [OS/GS]. GS icon appears on the display.
GS Scanning checks the Instant Priority Channel for 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, UH5040R will continue
monitoring the Priority Channel for activity while listening to the active one.
To deactivate SCAN, press the [SCAN] button or the PTT button on the microphone.
NOTE
If SCAN is deactivated while it is tuned to an active channel, the
UH5040R will stay on that active channel.
If none of the channels are active, the UH5040R will reinstate the scan
start channel.
NOTE
If OS/GS Scanning is initiated when there are no channels programmed
in OS/GS memory, an error tone will be heard and scanning will not
start (see Programming Scan Channels - below).
