About channels
This unit has 80 channels, but not all of these are available; several are
prohibited for voice transmission and other are restricted, as explained below.
The selected channel is displayed on the LCD.
• Channels 5 and 35
are for emergency calling. Do not use these channels
in non-emergency cases. According to AS/NZS 4365:2011, the operation
of selective calling (including CTCSS and Scrambler) is prohibited on
designated emergency channels 5 and 35.
• Channels 22 or 23
are prohibited for the transmission of speech
telephony signals, according to AS/NZS 4365:2011.
• Channels 61, 62 and 63
are reserved for future use. They cannot be
activated until approved by the ACMA CBRS Class Licence in Australia.
• Channels 1-8 and 31-38, 41-48 and 71-78
are used as repeater
channels with 750kHz offset. Channels 1-8 and 41-48 are used for mobile
reception, and channels 31-38 and 71-78 for mobile transmission.
Only use this
repeater function
when a long distance communication via
the local repeater facility is specifically required. Unless it is necessary,
avoid operation on locally used repeater input channels (channels 31-38
and 71-78) or locally used repeater receiving channels (channels 1-8 and
41-48).
• Channel 11
is the customary calling channel in Australia for establishing
communication.
• Channel 40
is the customary road vehicle channel.
NOTE:
This product is made to the new standard 2011 version. There are
possible operational issues during the changeover from the old
version 25kHz to the new version of 12kHz channel spacing. They
include the consequences of narrowband (with 2.5kHz deviation)
transmissions being received on the old wideband equipment, and
wideband (with 5.0kHz deviation) transmissions being received on
newer narrowband equipment.
There is a possibility of interference due to the older equipment being
operated on channels adjacent to new narrowband channels.
The list of currently authorised channels can be obtained from the
ACMA website in Australia and the MED website in New Zealand.
