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.

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 the two way
radio.” Obey all signs and instructions.

WARNING
Transmit and Receive Procedure
Your two-way radio contains a transmitter and
a receiver. To control your exposure and ensure
compliance with the general population/uncontrolled
environment exposure limits, always adhere to the
following procedure:
• Transmit no more than 50% of the time.
• To receive calls, release the PTT button.
•
To transmit (talk), press the Push to Talk (PTT) button.
Transmitting 50% of the time, or less, is important
because the radio generates measurable RF energy
exposure only when transmitting (in terms of measuring
standards compliance).
Always hold the radio approximately 5cm in front of your
mouth with the antenna pointing away from your head.
Radio Operation and EME Exposure
Unauthorized antennas, modications, or attachments
could damage the radio and violate compliance.
Do NOT hold the antenna when the radio is “IN USE.”
Holding the antenna reduces the effective range.
Do not use the radio if the antenna is damaged. If a
damaged antenna makes contact with your skin, a
minor burn can result.
If you wear a radio on your body when transmitting,
always t the radio on the belt clip (supplied). Always
ensure the radio and it's antenna are at least 5cm from
your body when transmitting.
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

Duplex operation via Repeaters
This feature allows to use local repeater stations that are designed
to automatically re-transmit your broadcast over a large area thus
giving you increased range.
Repeaters stations are privately operated radio systems installed
throughout Australia.
For example, if you wish to access a repeater station in your area
which operates on channel 2 you only need to set the Duplex
access on this Channel.
So, if you are in the range of a local repeater which transmits on
channel 2, after setting your radio to allow access of the repeater
on that channel, you will select channel 2 as normal, but during
transmit operation your radio will automatically transmit to the
repeater on channel 32.
Turning on/off Duplex on channels
a. Select the required channel to suit the repeater station you
wish to access (Channels 1 – 8 and 41 – 48)
b. Press the Menu button twice, "RPT" icon will display
c. Press the UP or DOWN button to set the Duplex function to On
or Off.
d. Press the PTT button to conrm your setting.
e. The RPT icon will display to indicate that Duplex is set on that
channel.
