After reading this manual, you may wish to consult with your Network Administrator regarding precise details of the configuration of this equipment for use in your application.VX-456 Operating Manual1
Important Information Concerning UHF CB RadioThe use of the Citizen Band Radio Service is licensed in Australia by the ACMA radio communications (Citizens Band Radio Stations) class licenceand in new Zealand by the ministry of EconomicDevelopment New Zealand (MED). A General userradio licence for Citizens Band Radio and operationis subject to conditions contained in those licences.The class licence for users and equipment operatingin 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 isavailable; however, radio transceivers can now operate in a narrower bandwidth and hence use lessspectrum.These radios are generally referred to as narrowbandor 12.5 kHz radios. By using 12.5 kHz channel spacing instead of 25 kHz, the 40 channels originally allocated can now be expanded to 80 channels therebydoubling the channel capacity and relieving congestion in the UHF CB/PRS band.2Original 40 channel wideband radios will continue tooperate on the original 40 channels, however they willnot be able to converse on the newer channels 41 - 80.The newer narrowband radios will be able to converse with all older 40 channel wideband radios onall channels 1 to 40 as well as the newer channelsallocated from 41 to 80.The mixing of narrowband and wideband radios inthe same spectrum can cause some possible operating issues of interference and varying levels of received volume.Possible IssuesWhen a new narrowband radio receives a transmission from an older wideband radio the speech maysound loud and distorted - simply adjust your radiovolume for best performance.When an older wideband radio receives a signalfrom a new narrowband radio, the speech may soundquiet - simply adjust your radio volume for best performance.VX-456 Operating Manual
Important Information Concerning UHF CB RadioDepending on how close your receiving radio is toanother transmitting radio, there can be interferencefrom the transmitting radio if it is using a channeladjacent to the channel you are listening to.Simply try going up or down a few channels fromthe currently selected channel.The above situations are not a fault of the radio buta symptom of operating wideband and narrowbandradios in the same bandwidth.This possible interference will decrease over timeas the population of wideband radios ages and decreases.Further information and updates are available fromthe Australian communications and media Authority (ACMA) at www.acma.gov.au and the Ministryof Economic Development (MED), radio spectrummanagement at: www.rsm.govt.nzVX-456 Operating ManualEmergency ChannelsThe ACMA has allocated channels 5/35 for emergency use only. Channel 5 is the primary simplexEmergency channel. Where a channel 5 repeater isavailable, 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 beused for anything other than emergency transmissions.Telemetry ChannelsACMA regulations have allocated channels 22 and23 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 channelsshall be added to those currently listed where voicetransmission is inhibited. Currently transmissions onchannels 61, 62 and 63 are also inhibited and thesechannels are reserved for future allocation.3

The time-out period can be changed to ashorter time by your dealer.IP57 Water Resistance: This radio is designed tomeet the IP57 Water Resistance specification. TheIP57 protected against the effects of immersion inwater up to 1 m depth for 30 minutes.Note: Water resistance of the transceiver (IP57: 1 meter / 30 minutes) is assured only when the followingconditions: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
FeaturesRepeater and Duplex Mode: Duplex operation allows the radio to transmit on a different frequency tothat which it receives. This allows operation throughrepeater stations.A repeater station consists of a linked transmitter/receiver combination installed in a prominent location.The repeater is designed to receive signals on adesignated channel and retransmit them on anotherchannel.Repeater stations, usually located on mountaintopsor other high locations, provide a dramatic extensionof the communication range for low-powered handheld or mobile transceivers.SimplexRepeater e Repeater channel is set in channels 1 - 8 and 41- 48 which have been allocated for repeater use. Inthe Repeater channel, the “D” notation is appearedon the right sideof the channel indication. Refer topage 34 for detailsof the Channel List.647X:z50.17774X:This radio can easily perform the Repeater operationby selecting the CH selector knob to the repeaterchannel.RRepeaterStationTX: 476.4250 MHzRX: 477.1750 MHzNormally, UHF radios transmit and receive on thesame frequency - known as simplex operation. However to communicate through repeaters, your radiomust be able to transmit and receive on differentchannels - otherwise known as Duplex operation.Channel[CB-01D]VX-456 Operating ManualChannel[CB-01D]5
