POSSIBLE ISSUES
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 best
performance.
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:

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
Priority Channel: A user programmable Priority channel feature allows your working channel to be instantly recalled at the
press of a key.
SigNal PrOCESSiNg
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: Identifies interference caused by strong local signals on adjacent channels and prevents
these from opening your squelch. Asm also minimises distortion on reception by fine tuning the receiver frequency to match
that of the incoming signal.
Dynamic Volume Control: Automatically compensates for variations in received audio level to provide a constant audio
output level to the speaker.
User Selectable Wide/Narrow Band Filter: to accommodate the blending of 80 channel narrow band radios with older
40 channel wideband radios.
PriVaCy FUNCTiONS
Voice inversion Scrambler: when activated, scrambles your voice so that communications are only intelligible to others
using the same scrambler technology.
inbuilt CTCSS & DCS: user selectable continuous tone coded squelch system and Digital coded squelch system provides
silent operation on individual channels.
in-Built SelCall with Quiet Mode: Provides selective calling of individuals or groups with fully user-adjustable 5-tone
transmitted selcall Ident. Also allows alphanumeric naming of up to 10 Idents for easier caller identification.
PHySiCal PrOPErTiES
Over Voltage Protection: special overvoltage detection circuitry protects the radio and warns of excessive voltage
conditions by flashing the display.
Rugged Construction: with Die-cast chassis
USEr CONTrOlS aND iNTErFaCE
Full Spectrum Backlighting: user adjustable, totally customisable backlight settings to match the vehicles dashboard
lighting or drivers preference.
High Contrast liquid Crystal Display: Fully detailed lcD provides a visual indication of the selected channel and all
selected functions at a glance.
Front and rear Microphone inputs: convenient front and rear microphone inputs to facilitate ease of installation and
operation across a range of vehicles.
Digital Signal Strength Meter: Provides a numeric signal strength indication in numbers from 0 to 9+
FEAtUrES
TraNSMiT (TX)
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.
rECEiVE (rX)
Silent Squelch Tail:
Eliminates the squelch noise burst normally audible when the squelch closes
User Programmable receive Channels:
95
Signal receive indicator: confirms that an incoming signal is being received
SCaNNiNg aND MEMOry FUNCTiONS
Microprocessor Controlled Frequency Synthesiser: Allows user programmable control of scanning, channel memories
and selected feature options.
Programmable Scan Function: scans the selected uHF cB channels with Group, open and network scan
functions available.
