VX-456 Operating Manual 1
IntroductIon
The VX-456 is meet the varied commercial radio needs of Australian industry. The compact case combines die-
cast chassis with the clean, tough poly-carbonate resin front panel. Its shockproof versatility will allow you to
operate the radio in the toughest environment.
The VX-456 allows to 80-channel capacity which can be programmed with an 8-character Alpha-Numeric Tag.
Important channel frequency data is stored in EEPROM and ash memory on the CPU, allows the user to
change the receiving frequency while the VX-456 is in the Field programming mode.
The pages which follow will detail the many advanced features provided in the VX-456 transceiver. After read-
ing this manual, you may wish to consult with your Network Administrator regarding precise details of the con-
guration of this equipment for use in your application.

Important InformatIon concernIng uHf cB radIo
The use of the Citizen Band Radio Service is li-
censed in Australia by the ACMA radio communica-
tions (Citizens Band Radio Stations) class licence
and in new Zealand by the ministry of Economic
Development New Zealand (MED). A General user
radio licence for Citizens Band Radio and operation
is subject to conditions contained in those licences.
The class licence for users and equipment operating
in the CB/PRS 477 MHz band has been amended.
This radio meets the new 80 channel standard.
In simple terms the same amount of spectrum is
available; however, radio transceivers can now op-
erate in a narrower bandwidth and hence use less
spectrum.
These radios are generally referred to as narrowband
or 12.5 kHz radios. By using 12.5 kHz channel spac-
ing instead of 25 kHz, the 40 channels originally al-
located can now be expanded to 80 channels thereby
doubling the channel capacity and relieving conges-
tion in the UHF CB/PRS band.
Original 40 channel wideband radios will continue to
operate on the original 40 channels, however they will
not be able to converse on the newer channels 41 - 80.
The newer narrowband radios will be able to con-
verse with all older 40 channel wideband radios on
all channels 1 to 40 as well as the newer channels
allocated from 41 to 80.
The mixing of narrowband and wideband radios in
the same spectrum can cause some possible operat-
ing issues of interference and varying levels of re-
ceived volume.
Possible Issues
When a new narrowband radio receives a transmis-
sion 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 per-
formance.
VX-456 Operating Manual 3
Important InformatIon concernIng uHf cB radIo
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 de-
creases.
Further information and updates are available from
the Australian communications and media Author-
ity (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 emer-
gency 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 chan-
nel 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 prohib-
ited the transmission of speech on these channels.
Consequently your radio has a transmit inhibit ap-
plied to channels 22 and 23.
In the event additional telemetry/telecommand chan-
nels 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.
Voice Encryption: The Voice Encryption feature
protect the privacy of your communication from
other groups.
Programmable Scan Function: Scans the selected
UHF CB channels with both Group and Open Scan
functions available.
Priority Channel: User programmable Priority
Channel feature allows your working channel to be
instantly recalled at the press of a programmable key.
High Contrast Liquid Crystal Display: Large
LCD (Liquid Crystal Display) provides a visual
indication of the selected channel and all selected
functions at a glance.
Field Programming Mode: Allows the user to
change the receiving frequency and Wide/Narrow
receiver lter of the memory channel by the simple
operation from the keypad.
User Menu Mode: Allows the user to define or
congure various settings of the radio by the simple
operation from the keypad.
In-Built CTCSS & DCS: User selectable Continu-
ous Tone Coded Squelch System and Digital Coded
Squelch system option provides silent channel op-
eration on individual channels.
TOT (Time Out Timer): This radio has a built-in
time-out timer that automatically limits transmis-
sions to a maximum of 3 minutes of continuous op-
eration.
This feature is required by the ACMA to prevent ac-
cidental blocking of the frequency should your PTT
switch become jammed or be otherwise pressed ac-
cidentally. The time-out period can be changed to a
shorter time by your dealer.
IP57 Water Resistance: This radio is designed to
meet the IP57 Water Resistance specification. The
IP57 protected against the effects of immersion in
water up to 1 m depth for 30 minutes.
Note: Water resistance of the transceiver (IP57: 1 me-
ter / 30 minutes) is assured only when the following
conditions:
r Battery pack is attached to the transceiver;
r Antenna is connected to the antenna jack;
r and MIC/SP cap is installed in the MIC/SP jack.
VX-456 Operating Manual 5
Repeater and Duplex Mode: Duplex operation al-
lows the radio to transmit on a different frequency to
that which it receives. This allows operation through
repeater stations.
A repeater station consists of a linked transmitter/re-
ceiver combination installed in a prominent location.
The repeater is designed to receive signals on a
designated channel and retransmit them on another
channel.
Repeater stations, usually located on mountaintops
or other high locations, provide a dramatic extension
of the communication range for low-powered hand-
held or mobile transceivers.
features
Normally, UHF radios transmit and receive on the
same frequency - known as simplex operation. How-
ever to communicate through repeaters, your radio
must be able to transmit and receive on different
channels - otherwise known as Duplex operation.
This radio can easily perform the Repeater operation
by selecting the CH selector knob to the repeater
channel.
The Repeater channel is set in channels 1 - 8 and 41
- 48 which have been allocated for repeater use. In
the Repeater channel, the “D” notation is appeared
on the right side
of the channel in-
dication. Refer to
page 34 for details
of the Channel List.

electromagnetic energy, always adhere to the following guidelines:
This radio is NOT approved for use by the general population in an uncontrolled exposure environ-
ment. This radio is restricted to occupational use, work related operations only where the radio op-
erator must have the knowledge to control his or her RF exposure conditions.
When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm) away
from your mouth and keep the antenna at least 2 inches (5 cm) away from your head and body.
The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical Push-to-
Talk congurations.
DO NOT transmit for more than 50% of total radio use time (50% duty cycle).
To keep the Body Worn conguration with the Vertex Standard CLIP-20 belt-clip, reduce the maxi-
mum operating duty cycle still more.
The radio is transmitting when the red LED on the top of the radio is illuminated. You can cause the
radio to transmit by pressing the P-T-T button.
When operate the radio with the Vertex Standard CLIP-20 belt-clip, make the transmission time as
short as possible, to keep the Body Worn conguration.
Always use Vertex Standard authorized accessories.
