When an older wideband radio receives a signal from a new
narrowband radio, the speech may sound quiet – simply adjust
your radio volume for best performance.
Depending on how close your receiving radio is to another
transmitting radio, there can be interference from the
transmitting radio if it is using a channel adjacent to the
channel you are listening to. simply try going up or down a
few channels from the currently selected channel.
the above situations are not a fault of the radio but a
symptom of operating wideband and narrowband radios in
the same bandwidth. this possible interference will decrease
over time as the population of wideband radios ages and
decreases.

Australian communications and media Authority (AcmA) at
www.acma.gov.au and the ministry of Economic Development
(mED), radio spectrum management at: www.rsm.govt.nz
EMERGENCy CHaNNELS
the AcmA has allocated channels 5/35 for emergency use
only. channel 5 is the primary simplex Emergency channel.
Where a channel 5 repeater is available, you should select
Duplex on cH 5.
NOTE: channel 35 is the input channel for the channel 5
repeater therefore channel 35 should also not be used for
anything other than emergency transmissions.
TELEMETRy CHaNNELS
AcmA regulations have allocated channels 22 and 23
for telemetry only applications and have prohibited the
transmission of speech on these channels. consequently your
radio has a transmit inhibit applied to channels 22 and 23.
In the event additional telemetry/telecommand channels are
approved by the AcmA, these channels shall be added to
those currently listed where voice transmission is inhibited.
currently transmissions on channels 61, 62 and 63 are also
inhibited and these channels are reserved for future allocation.
FEaTURES
• Microprocessor Controlled Frequency Synthesiser:
Allows user programmable control of scanning, channel
memories and selected feature options.
• Full Spectrum Backlighting: user adjustable, totally
customisable colour backlight settings to match the vehicle’s
dashboard lighting or drivers preference.
• Digital Signal Processing: measures, filters and
compresses standard analogue audio signals and converts
them into digital format. Allows advanced rF and audio
processing techniques to be applied to maximise the
radio’s performance.
• Advanced Signal Management (ASM): Identifies
interference caused by strong local signals on adjacent
channels and prevents it from opening your squelch. Asm
also minimises distortion on reception by fine tuning the
receiver frequency to match that of
the incoming signal.
this prevents your squelch from opening to unwanted
interference and ensures that incoming signals remain clear
and undistorted even when they are slightly off-frequency.
• Dynamic Volume Control (DVC): Automatically
compensates for variations in received audio level resulting
in a constant audio output level to the speaker.
• Voice Inversion Scrambler
When activated, scrambles your voice so that
communications are only intelligible to others using the
same scrambler technology.
• Programmable Scan Function: scans the selected uHF
cB channels with both Group and open scan functions
available.
• Individually Programmable DUPLEX function: user
selectable for only those individual channels in your area
that have repeaters, leaving the others free for use as extra
simplex channels.
• Priority Channel: A user programmable priority channel
feature allows your working channel to be instantly recalled
at the press of a key.
