Operating Instructions
DTX4000 80 Channel UHF Citizen Band Radio
![](/html/44/44cc/44cc89b7a9912ddaa0bfe57a02e44051a1988b6acad4898fc5d84785e7dbb740/bg2.png)
This unit complies with all relevant Australian
and New Zealand approval requirements
AS/NZS 4365:2011
The ACMA increased the number of available UHF CB channels.
To provide additional channel capacity within the UHF CB Band the ACMA has increased the number of available
channels by changing from wideband to narrowband channels and adding the additional channels between the
existing 40 channels. Some of the new channels are locked and cannot be used, see channel chart later in this user
guide 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 conicts, 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 congurations 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 External Speaker
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 EXT –SPK socket on the rear of the unit.
