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.

VX-456 Operating Manual2

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

congure 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.
