Introduction

Congratulations on your purchase of the

Sundowner UH-O53.

This 16-channel personal

UHF-CB 2-way radio represents a great value in professional portable communications. You'll find that it provides reliable, consistent performance for short-distance 2-way personal communications.

The Sundowner UH-O53 is designed to operate in simplex mode on CH 1 to CH 16 or duplex mode on CH 1 to CH8 where repeater service is available.

Warning!

The Citizens Band Radio Communication

Service (CBRS) is under the jurisdiction of the

Australian Spectrum Management Agency

(SMA). Any adjustment or alteration which will change the performance of the transceiver's original SMA type acceptance is STRICTLY

PROHIBITED.

Replacement 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.

Getting Started

Charging the Battery

Before using the UH-QS3for the first time, or whenever the red BATT LO indicator lights showing the battery is Iow, you should fully charge the unit.

UH-O53 5

To charge the nickel-cadmium battery:

Using the AC Adaptor/Charger

1. Plug the AC adaptor/Charger into the Charging

Jack located on top of the unit.

WARNING!

Use only the supplied AC

Adaptor/Charger.

Any other AC Adaptor or external power plug having over-voltage or reversed polarity can cause overheating or damage to the circuitry.

2. Plug the charger into a standard AC outlet.

To fully charge the battery, leave the Adaptor/

Charger connected for between 9 and 11 hours.

Note: Switch OFF the unit while the battery is charging.

"

3. When charging is complete, disconnect the

Adaptor/Charger from the AC outlet, and from the radio.

Mounting the Flexible Antenna

Place the end of the antenna onto the TNC connectoron top of the radio and turn clockwise untiltight.

Installing the Belt Clip

Place the Belt Clip slightly above the mounting area on the back of the radio, and press downward and in.

Qperation

Note: Before operating the UH-oS3 for the first time, make sure you have fully charged the battery.

1. Turn the UH-oS3 on by rotating the

On-OffNolume Control clockwise until you hear a click.

2. Adjust the Volume Control to a comfortable level.

3. Turn the Squelch Control fully counterclockwise. You will hear background noise, and the BUSY Indicator will light. Turn the

Squelch Control just until the background noise disappears and the BUSY Indicator goes out. At this setting, the received signal must be strong enough (>0.25jlV) to break squelch and be heard.

4. If the channel is clear, the BUSY Indicator will be out. (If the BUSY Indicator is lit, the channel is busy. Wait until the light goes out before you begin transmitting.) Press the PTT

Switch to transmit. The TX Indicator lights to indicate you are transmitting. Hold the built-in microphone (or optional Speaker/Microphone) approximately two inches from your mouth and speak clearly in a normal voice.

5. When you are through speaking, release the

PTT switch and listen for a reply. (The TX

Indicator goes out.)

6. When you are finished using the radio, be sure to turn it off to conserve battery power.

Simplex/Duplex Communication

Duplex Operation allows the Sundowner

UH-oS3 to operate via a repeater station on

Channels 1 through8. The set receiveson these channels but transmits 750 kHz higher than the receiverfrequency.

When the Simplex/Duplex switch is set to

Simplex position, the set receives and transmits on the same channel. (SimplexCommunication)

To use Duplex operation on a Channel where

Repeater Service is available, set the

Simplex/Duplexselectorswitch to "Duplex".

To put the Duplex channel back to normal

Simplex operation, set the Simplex/Duplex

Selectorswitch to "Simplex".

Low Battery Level Detection

Uniden Sundowner UH-oS3 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.

When the PTT switch is pressed and the TX

LED blinks. It means the battery level is already

Iow and needs recharging. Under this condition, the unit no longer transmits RF Power. Have your battery charged fully or replaced by a fully charged battery to resume normal operation.

Care and Maintenance

The

UH-OS3 is designedto give you trouble-free service. There are no user-serviceable parts inside, and except for occasionally replacingthe rechargeable battery, no maintenance is required.

Warning!Unidendoes not representthis unit to be waterproof Do not expose the unit to moisture. Rain, dew, or other liquids may damage the internalcomponents.

Replacing the Rechargeable Battery

When it is time to install a new battery, use only the one made for this radio. Any other type of battery may damage your unit.

To replace the battery:

1. Remove the Belt Clip by lifting the tab and carefully sliding upward and out.

2. Remove the battery compartment cover on the back of the radio by pressing in and sliding the cover down and off.

3. Remove the rechargeable nickel-cadmium battery and replace with a new one. Be sure the terminals on the battery match up with the contacts in the radio.

4. Replace the battery compartment cover by sliding it back into place until it clicks.

5. Replace the Belt Clip.

Note: Be sure to recharge the battery before using the radio.
