Page 3: Important Information
AVOID storing or using your radio DO NOT attempt to modify your radio where temperatures are below -20°C in any way. or above +60°C. ALWAYS charge your radio at normal room temperature. IMPORTANT INFORMATION CONCERNING UHF CB RADIO T he use of the Citizen Band radio service is licensed in Australia by the ACMA Radiocommunications (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. T he 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. I n simple terms the same amount of spectrum is available; however, radio transceivers can now operate 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 spacing instead of 25 kHz, the 40 channels originally allocated can now be expanded to 80 channels thereby doubling the channel capacity and relieving congestion in the UHF CB/PRS band.

Page 5: Telemetry Channels
TELEMETRY CHANNELS ACMA regulations have allocated channels 22 and 23 for telemetry only applications and have prohibited the transmission of speech on these channels. Consequently the TX680 has a transmit-inhibit applied to channels 22 and 23. 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. 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. Programmable Scan Function: Scans up to 80 UHF CB channels. • • In-built CTCSS: User selectable Continuous Tone Coded Squelch system for quiet channel operation. • 3 watt/1 watt RF Power: When transmitting in close range you can conserve battery power by using the Low Power setting. • Individually Programmable Duplex Function: User selectable for those individual repeater channels in your area. Power-Save Feature: Sleeps during periods of inactivity. -
