Operational notes
i. The use of the citizen band radio service is licenced in Australia by the ACMA
Radiocommunications (Citizens Band Radio Stations) Class Licence and in New
Zealand by the Ministry of Economic Development (MED) General User Radio
Licence for Citizen Band Radio and operation is subject to conditions contained
within these licences.
ii. Always listen on a channel (or observe the channel busy indicator) to ensure it is not
already being used before transmitting.
iii. In Australia, channel 11 is the customary calling channel for establishing
communication. Channel 40 is the customary road vehicle channel.
iv. In Australia, except in an emergency, a CB transmitter shall not be operated on UHF
emergency channels 5 and 35.
v. No voice transmissions are permitted on data channels 22 and 23 (voice operation is
inhibited on these channels).
vi. Channels 61, 62, and 63 are for possible future use and shall not be activated until
approved by the ACMA CBRS Class Licence in Australia or the MED GURL in New
Zealand. No voice transmissions are permitted on these channels (voice operation is
inhibited on these channels).
vii. The user of this UHF CB communications device shall not transmit Selcall tones for
longer than 3 seconds during any 60 second period.
viii. UHF CB repeaters extend the operational range of your radio. Repeaters operate
utilising two channels (repeater input/repeater output). It is important to avoid
operation on locally used repeater input channels (in the channel range of 31 to 38
and 71 to 78) or locally used repeater output channels (in the channel range of 1 to
8 and 41 to 48), unless long distance communication via the repeater is specifically
required. See the section on repeater operation for more information.
ix. Please be aware that the UHF CB network may experience possible operational
issues during the changeover to narrowband. This transceiver operates on 12.5 kHz
channel spacing. During the changeover period from 25 kHz to 12.5 kHz spacing,
there may be some loss of quality when 12.5 kHz (narrowband, 2.5 kHz deviation)
transmissions are received on 25 kHz (wide band, 5.0 kHz deviation) equipment, and
vice-versa. There may also be interference due to older equipment being operated
on channels adjacent to new narrowband channels, as the channel setting on these
may cause some ‘overlap’. A list of currently authorised channels can be found on
the ACMA website (Australia) and on the MED website in New Zealand.
