IMPORTANT NOTICE
READ ALL INSTRUCTIONS carefully and completely before operating your radio and retain this manual for future reference.
•NEVER connect the radio to a power source other than via supplied power cable and 12-24 volts DC.
•DO NOT place your radio in front of a vehicle airbag.
•DO NOT attempt to modify your radio in any way.
•ALWAYS mount the radio on the supplied bracket and more than 20cm from the user.
•ALWAYS switch off your radio where notices are displayed that restrict the use of two-way radio or mobile telephones.
•DO NOT hold radio / speaker to ear.
Wiring Diagram
The TA-995 can handle power input of 12-24V and a peak current of 3A the wiring diagram follows;
Please ensure installation follows above wiring diagram and installation requirements to avoid damage or abnormal functionality of the radio.
ACMA Standard
The use of the Citizen Band radio service is licensed in Australia by the ACMA Radio communications (Citizens Band Radio Stations) Class License and in New
Zealand by the Ministry of Economic Development (MED) General User Radio License (GURL) for Citizens Band Radio, and operation is subject to conditions
contained in those licenses.
In Australia there are numerous repeater sites that input/receive channels for long distance communication between sites. The repeaters work by taking input
on channels 31 to 38 and 71 to 78, and re-broadcast the signal on channels 1 to 8 and 41 to 48, to extend the range of the communication. While operating in
Australia certain transmissions must meet the ACMA standard they are as follows:
•CB transmitter shall not be operated on UHF emergency channels 5 and 35.
•No voice transmission is permitted on data (telemetry/telecommand) channels 22 and 23.
•Before transmitting on a channel always listen in on the channel selected to ensure it is not already being used before transmitting.
•Avoid operation on locally used repeater input channels 31 to 38 and channels 71 to 78 or locally used repeater receiving channels 1 to 8 and channels
41 to 48, unless long-distance communication via the repeater facility is specifically required.
•Transmissions on channels 61 to 63 are inhibited and are reserved for future allocation.
The TA-995 meets the ACMA standard and will inhibit voice operation on channels 22 and 23 and inhibit all operations on channels 61 to 63.
In the event that additional telemetry/telecommand channels are approved by the ACMA, these channels shall be added to those currently listed where voice
transmission is inhibited.
The TA-995 operates on narrowband (2.5 kHz deviation) 12.5 kHz channel spacing. This can lead to potential operational issues with older equipment still
operating on wideband (5.0 kHz deviation) 25 kHz channel spacing. The original 40 channels were designed for wideband channel spacing and with the new
technology narrowband channel spacing has halved the channel spacing which is how we now have 80 channels. Older equipment still operating on wideband
will only operate on original 40 channels and could potentially interfere with narrowband 41 to 80 channels which sit inside the original 40 channel band. Due
to the deviation differences between the two channel spacings narrowband and wideband there will be volume differences of the communication between the
old equipment and the new equipment. A list of currently authorized channels can be obtained from the ACMA website in Australia and the MED website in
New Zealand.
