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)
User Selectable Wide/Narrow Receive Filter
User Programmable Receive-Only Channels: Use the radio’s front panel controls to program up to 95
of your own receive-only channels (in 5 banks of 19 channels) within the 403-520 MHz frequency range.
SCANNING AND MEMORY FUNCTIONS
Microprocessor Controlled Frequency Synthesiser:
Allows user programmable control of scanning,
channel memories and selected feature options.
Priority Channels:
Two user programmable Priority channels allow your working channels to be instantly
recalled at the press of a key.
Programmable Scan Function:
Scans the selected UHF CB channels with Group, Open and Network
Scan functions available.
Auto Skip:
Temporarily removes annoying busy channels from the scan group.
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 (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
an incoming signal. This prevents your Squelch from opening to unwanted
interference and ensures incoming signals remain clear and undistorted even when 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.
PRIVACY FUNCTIONS
Voice Inversion Scrambler: When activated, scrambles your voice so that communications are only
intelligible to others using the same scrambler technology.
In-Built CTCSS & DCS: User selectable Continuous Tone Coded Squelch and Digital Coded Squelch
System option provides silent channel 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
Overvoltage Protection: Special overvoltage detection circuitry protects the radio and warns of excessive
voltage conditions by flashing the display.
Dual Microphone Input Sockets: Front and rear microphone sockets to match most installation needs.
Both sockets can be used independently or simultaneously.
USER CONTROLS AND INTERFACE
High Contrast Liquid Crystal Display: Fully detailed LCD provides a visual indication of the selected
channel and all selected functions at a glance.
Full Spectrum Backlighting: User adjustable, totally customisable colour backlight settings to match the
vehicle’s dashboard lighting or drivers preference.
