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 communicalion Sen/ice (CBRS) is under the jurisdiction of the Australian Management Agency (SMA). Any adjustment or alteration which wilt 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).

GETTING STARTED

Antenna

To attach the antenna to the TNG 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-056 comes with a standard recharge able Ni-Cd Battery Pack. An optfonal 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 bcks in place.
Page 9 UH-056
Recharging the Nickel-Cadmium Battery Pack
Mote: Before charging, be sure that the power (ON/OFF
Volume control) is turned OFF. Recharge the Ni-Cd Battery ONLY when the unit indicates a LOW BATTERY 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 Instaiiation

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
radio. Insert the 2 screws into the
corresponding holes and tighten.

2. Press the O or O switch to select the desired
channel.
3. Press the monitor switch (Auto-squelch turns OFF).
4. Rotate the ON/OFF Volume control to adjust the speaker
volume to a comfortable level.
5. Press the Monitor switch (Auto-squelch turns ON).
Auto-Squelch
Automatically eliminates the unwanted "rushing" noise when the unit is turned ON.
Note: To listen to weak signal transmissions, switch OFF
" ' UP DOWN ' '
- press the Monitor Switch to set the Auto-squelch feature ON or OFF
the Auto-squelch feature (Squelch is on minimum level).
Channel Scan
UP
W/hen you pressed the O Key for 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.
To resume scanning, press the Q Key.
UP
If there is too much activity on a certain channel and you
w^h to exclude it from being scanned, simply press the
O Key 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).
Pageii
UH-056
To disable scanning:
iXMN
- when on an active channel, press the O Key and
the unit stays on the active channel.
U3=> DCWN
- while scanning, press the O or O Key. The unit
returns to the channel where scan function is acti vated.
- press the PTT 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:
1. UsingtheOoi" O switches, manually select the
DP OOM4
uo
desired channel and press the O button. The locked­out channel blinks.
2. While scanning, when the unit stops on the channel you wish to lock-out because of its too much activity, simply
VO
press the O Key and it will be automatically removed from the scan list. Scanning resumes.
To remove the lock-out condition from a channel, manually
(JO
select the channel and press O button again. The channel stops blinking.

TRANSMIT

1. The maximum transmit power output level ot UH-056 is 5 watts.
To switch to low power, press the HI/LO switch. LO appears on the LCD and the transmit power output level is changed to 1 watt.
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. Before you transmit, listen for activity on the selected channel.
3. When the channel is dear, 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 45-6egree angle away from your head. Speak in a dear, 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-056 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
O button, DUP indicator appears on the LCD Display,
To put the Duplex programmed channel back to normal^
Simplex operation, select the channel and press the O
button again. DUP indicator disappears from the LCD
Display.
Page 13 UH-056

Low Battery Level Detection

Uniden Siindowner UH-056 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 low 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 PTT
switch and emit an error tone everytime you try to transmit.
