Using the AC Adaptor/Charger

1. Plug the AC adaptor/Charger into the Charging

Jack located on top of the unit.

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.

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 counter-

clockwise. 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.

Channels1through8.Theset receivesonthese

channelsbut transmits750 kHz higherthan the

receiverfrequency.

When the Simplex/Duplex switch is set to

Simplexposition,the set receivesandtransmits

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

determinewhetherthe powerinsidethe 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.
