Operating Instructions

DTX4300 80 Channel UHF Citizen Band Radio

This unit complies with all relevant Australian

and New Zealand approval requirements

AS/NZS 4365:2011

Why has the ACMA increased the number of available UHF CB channels?

To provide additional channel capacity within the UHF CB Band the ACMA will over the next 5 years change the

majority of the current wideband 40 channel use to narrowband 80 channel use.

During this time wideband channel use will be gradually phased out as users upgrade their existing radio’s.

This means that the new Oricom narrowband radio you have purchased will have more channels than older wideband

radios. Some of these channels are locked and cannot be used, (see the attached channel chart for more information).

When did this take place?

Early in 2011 new AS/NZS Standards came into effect allowing operators to use additional narrowband channels and

also use narrowband transmissions on some current wideband channels. This increased the number of channels up

to 80, 75 of which are useable voice channels.

What issues may users experience during the transition phase?

When a new narrowband radio receives a transmission from an older wideband radio the speech may sound loud

and distorted – simply adjust your radio volume for the best listening performance. When an older wideband radio

receives a signal from a new narrowband radio the speech may sound quieter - simply adjust your radio volume for

best listening performance. When operating a narrowband radio or Channel 41 - 80 interference is possible from

wideband radios transmitting on high power or on adjacent frequency.

The issues described above are not a fault of the radio but a consequence of mixed use of wideband and narrowband

radios.

It is expected that as older wideband radios are removed from service that this issue will be resolved. Most radios in

use will be narrowband eliminating this issue.

Safety Information and Warnings

WARNING

Potentially Explosive Atmospheres

Turn your radio OFF when in any area with a potentially

explosive atmosphere. Sparks in such areas could cause an

explosion or re resulting in injury or even death.

NOTE: Areas with potentially explosive atmospheres are often,

but not always clearly marked. They include fueling areas such

as below deck on boats; fuel or chemical transfer or storage

facilities; areas where the air contains chemicals or particles,

such as grain, dust, or metal powders; and any other area where

you would normally be advised to turn off your vehicle engine.

Blasting Caps and Areas

To avoid possible interference with blasting operations, turn

your radio OFF near electrical blasting caps or in a "blasting

area" or in areas posted: "Turn off two way radios." Obey all

signs and instructions.

Electromagnetic Interference/Compatibility

Nearly every electronic device is susceptible to electromagnetic

interference (EMI). To avoid the possibility of electromagnetic

interference and/or compatibility conicts, turn off your radio

in any location where posted notices instruct you to do so such

as health care facilities.

Installation of your Oricom Radio

CAUTION

When installing your radio in your vehicle, check that

during installation you do not damage any wiring or vehicle

components that may be hidden around the mounting position.

Ensure the installation does not interfere with the operation of

the vehicle and meets all regulatory and safety retirements for

accessories tted to your vehicle.

For optimum performance your radio needs to be installed

correctly. If you are unsure about how to install your radio, we

suggest you have your radio professionally installed by a UHF

specialist or Auto electrician. When installing the radio, avoid

mounting it close to heaters or air conditioners. Never press

the PTT or CALL button before connecting the antenna to the

radio.

Wiring Methods

There are two possible wiring congurations for connecting to the

Vehicles power supply.

A. Radio stays ON when the ignition is switched OFF

Connect the radio's negative (black) lead to the vehicle chassis, or

directly to the batteries negative terminal.

Connect the radio's positive (red) lead via the 2 Amp fuse to the

battery's positive terminal. Alternatively, the positive lead could be

connected at the fuse box at a point that has DC Power continuously

available (preferably the battery side of the ignition switch) via the 2

Amp fuse.

B. Radio turns OFF with the ignition switch

Connect the radio's negative (black) lead to the vehicle's chassis, or

directly to the batteries negative terminal.

Installation of your Oricom Radio

The radio's positive (red) lead should connect to an accessory point in

the vehicle's fuse box via the 2 Amp fuse.

Antenna information

The antenna (not supplied) is of critical importance, to maximize your

output power and receiver senstivity.

A poorly installed, inferior quality antenna or one not designed for the

correct frequency band will give poor performance. You should only

purchase an antenna designed for the 477MHz frequency band.

Antenna installation

1. Connect the antenna to the rear antenna socket using a PL259 coaxial

connector (not supplied).

2. To obtain maximum performance from the radio, select a high quality

antenna and mount it in a good location. Never press the PTT or

CALL button before connecting the antenna to the radio.

Optional accessories

If required you may install an external (8 ohm, max 5w power) speaker

tted with a 3.5mm plug (not supplied).

Depending on the installation it may be necessary to use an external

speaker (not supplied) to give improved volume and clarity. This can be

plugged into the external speaker (SP) socket on the rear of the unit.

Operations

Turning on the Power

Press and hold the Channel selector.

Setting the Volume

Turn the channel selector clockwise to adjust the sound level for

comfortable reception.

On the microphone push the up or down buttons to increase or decrease

the volume. If held down the volume will increase or decrease quickly.

Selecting a channel

Press channel selector once. "CH" will appear on the LCD.

Select the channel by rotating the channel knob.

On the microphone push the mode button and select the channel using

the up or down buttons.
