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 will 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.

INSTALLATION
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.
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.
Screw the mounting bracket and the remote head bracket to rm surfaces.
To install the Radio;
1. Fix the radio bracket in a suitable location.
2. Then x the radio in the bracket using the thumb screws.
Note
The radio contains a built-in loud speaker, The radio can be installed ‘out of the
way’ and an external speaker can be used as an alternative (not supplied).
To mount the Remote Head (UHF180)
The remote head is supplied with a slim mounting bracket and thumb screws.
Its small size and light weight design allows it to be mounted in almost any
convenient position accessible to the driver.

1. Fix the mounting bracket in place by screwing through the slots in the
bracket.
2. Fix the remote head unit to the mounting bracket with the thumb screws
provided.
3. Connect the standard microphone to the remote head socket, and tighten up
the thumb screw.
Fitting the Controller Microphone Speaker (UHF280)
The Remote Head uses an 8 pin telephone style plug and socket:
1. Position the microphone plug so the plastic ap faces downwards, and press
the plug into the socket until it ‘clicks’.
2. Gently press the rubber boot into the hole surrounding the socket so that the
slot around the boot ts neatly inside the rim of the entry hole.
3. If required use the external cable and joiner (supplied) to allow the radio to be
installed further from the Controller Speaker Microphone.
Installation

12
Disconnecting the Remote Head/Speaker Controller Microphone
It is recommended that the remote head be left permanently connected to the
radio, but if it must be disconnected, proceed as follows:
1. Lift the rubber boot and the lip of the raised area on the front panel.
2. Ease the rubber boot out of the cable entry hole and slide it along the cable
away from the front panel.

same time gently pull the plug from the socket (see previous page).
Controller Speaker Microphone; part number, CSPKMIC
Standard Microphone; part number, MIC050
These can be purchased from the dealer you purchased the radio from or
directly from www.oricom.com.au.
DC Power Connection
The Radio is designed for 13.8 Volt DC, negative earth installations only (i.e.
where the negative battery terminal connects to the chassis of the vehicle).
For installation on 24 volt systems an inverter (not supplied) will need to be
used.
Over voltage protection
The radio has a high voltage input detection system, to warn you if an
overvoltage situation occurs.
Eg.: If the power supply voltage exceeds 17volts DC, the channel display (LCD
backlight) will ash in 3 different colors when the unit is turned on.
In additon, when transmitting, the TX indicator will automatically select a low
power output.
If the overvoltage warning appears, you must switch your radio off and
disconnect it from the power source, before locating the cause of the trouble.
The power source must not exceed 30volts.
Installation

13
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 +13.8 Volts 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.
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.
