Introduction
Welcome to the world of CB Radio Communication. You
have chosen the most reliable, highly engineered, ultra-
precise piece of communication equipment.
Description
Your UNIDEN Sundowner UH-056 represents the most
advanced portable radio ever designed for use in the UHF
Citizens Band Radio Service. This UH-056 UHF CB radio
has been built to give you a rugged, reliable equipment that
will provide you with years of trouble free service.
You are encouraged to thoroughly read the rest of this
operating guide to acquaint yourself with the superior
characteristic and operation of your transceiver. This full
featured radio operates on any of the 40 UHF frequencies
designated as Citizens Band Channels by the Spectrum
Management Agency.
WARNING
The Citizens Band Radio communication Service (CBRS)
is under the jurisdiction of the Australian Management
Agency (SMA). Any adjustment or alteration which will
change the performance of the transceiver's original SMA
type acceptance is STRICTL Y PROHIBITED. Replace-
ment or substitution of power or frequency determining
components e.g. Crystals, Transistors, ICs, Diodes, etc.
with other than those recommended by UNIDEN will
cause violation to the SMA type acceptance technical
requirement.
Licensing Requirements
Before using your transceiver, you must obtain a Citizens
Band Radio License from the Spectrum Management
Agency (SMA). Application forms and brochures relating to
CBRS are available at your nearest SMA office. Mail the
completed application form and the appropriate fee to the
Communications Manager, in the State or Territory in which
the station will be operated.

GETTING STARTED
Antenna
To attach the antenna to the TNC connector on top of your
radio, press down and rotate the antenna base clockwise
until it seats firmly into place.
Battery Information
The Sundowner UH-O56 comes with a standard recharge-
able Ni-Cd Battery'Pack. An optional heavy duty recharge-
able Ni-Cd Battery Pack is also available.
Installation
THE RECHARGEABLE NICKEL-CADMIUM BATTERY
PACK MUST BE CHARGED FULLY BEFORE USING IT
FOR THE FIRST TIME.
When installing or removing the rechargeable Battery Pack,
be sure that the power (ON/OFF Volume control) is turned
OFF.
To remove the Battery Pack, push up on the release button
and slide the Battery Pack away from the radio.
To replace, align the Battery Pack rails with the transceiver
and slide toward the transceiver unit until the Battery Pack

indicates aLOW BA TTERY condition.
(TX LED blinks during TRANSMIT)
Insert the discharged Battery Pack in the rapid charger, or
connect the trickle charger to the side of the unit.
Using the trickle charger, the standard pack charges fully in
8 hours, and the heavy duty pack in 12 hours. If you have a
rapid charger, the standard pack charges fully in 1.5 hours,
and the heavy duty pack charges fully in 2 hours.
DO NOT leave the Batteries on charger for an extended
period of time.
Belt Clip Installation
Place the Belt Clip on the
mounting area on the back of
the radio, making sure the
holes in the clip line up with
the threads in the back of the

OPERATION
RECEIVE
1. Turn the radio ON. Rotate the ON/OFF Volume control
clockwise until you hear the cliyk. A channel number
should appear in the LCD Display.
UP DOWN
2. Pressthe 0or 0switch to select the desired
channel.
3. Press the monitor switch (Auto-squelchturns OFF).
4. Rotate the ON/OFF Volume control to adjust the speaker
volume to a comfortable level.
5. Press the Monitor switch (Auto-squelchturns ON).
Auto-Squelch
Automatically eliminates the unwanted "rushing" noise when
the unit is turned ON.
- press the Monitor Switch to set the Auto-squelch
feature ON or OFF
Note: To listen to weak signal transmissions, switch OFF
the Auto-squelch feature (Squelch is on minimum
level).
Channel Scan UP
When you pressed the 0Keyfor more than 1.5 seconds,
the scan feature starts and the SCN indicator appears on
the LCD.
Scanning stops automatically on any active channel that is
not Locked-out, receives a call and you hear the caller.
UP
To resume sc~nning, press the 0Key.
If there is too much activity on a certain channel and you
wish to exclude it from being scanned, simply press the
uo
0Key when on that channel. It will be automatically
removed from the scan list, and scanning resumes (please
see page 12 on how to create a channel scan list).
Page 11 UH-O56

To disable scanning: DOWN
- when on an active channel, press the 0Key and
the unit stays on the active channel.
UP DOWN
- while scanning, press the 0or 0Key. The unit
returns to the channel where scan function is acti-
vated.
- press the PIT switch. When the unit is on an active
channel, it transmits on the same channel.
When scanning, the unit transmits on the channel
where scan function is activated.
SCN indicator disappears from the LCD Display.
Drop Out Delay
While scanning, the radio stops at a busy channel and
receives a transmission. When the received call is over, the
unit will wait for three seconds for the return of the signal.
Otherwise it resumes scanning.
Create a Channel Scan List with Channel Lock-Out
Feature
You may have certain channels that you do not want to hear
every time you scan. These are channels that are busy in a
major portion of time, and the scanning stops at that
channel(s) often enough to interrupt the scan cycle. You
can Lock-out those channels so they are not scanned.
There are two ways to exclude channels from being
scanned:
UP DOWN
1. Using the 0or 0switches, manually select the
LiO
desired channel and press the 0button. The locked-
out channel blinks.
2. While scanning, when the unit stops on the channel you
wish to lock-out because of its too much activity, simply
LiO
press the 0Key and it will be automatically removed
from the scan list. Scanning resumes.
To remove the lock-out condition from a channel, manually
LiO
select the channel and press 0button again. The channel
stops blinking.
UH-O56 Page 12

TRANSMIT
1. The maximum transmit poweroutput level of UH-O56is
5 watts.
To switch to Iowpower, press the HI/LO switch. LO
appears on the LCDand the transmit poweroutput level
is changed to 1watt.
To switch back to High power, press the HI/LO switch
again. The TX power returns to high and the LO
indicator disappears from the LCD.
2. Beforeyou transmit, listen for activity on the selected
channel.
3. When the channel is clear, press the PTT switch to
transmit. The TX LED comes on when you transmit.
Hold the radio with the microphone approximately two
inches in front of your mouth with the antenna at
approximately a 45-degree angle away from your head.
Speak in a clear, normal, conversational voice.
4. When you are finished speaking, release the PTT switch
and listen for an answer.
Simplex / Duplex Communication
Duplex Operation allows the Uniden Sundowner UH-O56 to
operate via a repeater station on Channels 1 through 8.
The set receives on these channels but transmits on
Channels 31 through 38 respectively.
When Duplex operation is disabled, the set receives and
transmits on the same channel. (Simplex Communication)
To activate Duplex operation on a Channel where Repeater
Service is available, select the channel and then press the
DUP
0button. DUP indicator appears on the LCD Display.
To put the Duplex programmed channel back to normal
DUP
Simplex operation, select the channel and press the 0
button again. DUP indicator disappears from the LCD
Display.
Page 13 UH-O56

Low Battery Level Detection
Uniden Sundowner UH-O56 has a built-in battery level
detector circuit. It evaluates your Battery Pack everytime
you transmit to determine whether the power inside the
Battery is still sufficient enough to support normal Receive
and Transmit communications.
The circuit will inform you in two ways.
1. When the PIT switch is pressed and the TX LED blink~
It means the battery level is already Iow and needs
recharging. You can still transmit, however, you must
finish the conversation and have your battery charged
fully to resume normal operation.
2. When the Blinking TX LED went unnoticed and the
Battery goes down to where normal communication car
no longer be supported, the circuit will disable the PIT
switch and emit an errortone everytime you try to
transmit.
