Page 3: Important Information Concerning Uhf Cb Radio
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. O riginal 40 channel wideband radios will continue to operate on the original 40 channels, however they will not 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 on all channels 1 to 40 as well as the newer channels allocated from 41 to 80. T he mixing of narrowband and wideband radios in the same spectrum can cause some possible operating issues of interference and varying levels of received volume. Possible issues W hen a new narrowband radio receives a transmission from an older wideband radio the speech may sound loud and distorted – simply adjust your radio volume for best performance. W hen an older wideband radio receives a signal from a new narrowband radio, the speech may sound quiet – simply adjust your radio volume for best performance. D epending on how close your receiving radio is to another transmitting radio, there can be interference from the transmitting radio if it is using a channel adjacent to the channel you are listening to. Simply try going up or down a few channels from the currently selected channel. T he above situations are not a fault of the radio but a symptom of operating wideband and narrowband radios in the same bandwidth. This possible interference will decrease over time as the population of wideband radios ages and decreases. -

Page 7: Powering The Radio
THE RAdIO Your radio is powered by a 7.4 volt Li-Ion battery pack. When the battery pack is new, it should be fully charged before being used for the first time. If left unused, your radio’s battery pack will discharge itself within a few months. If you have not used your radio for some time, you will need to recharge the battery pack before use. WARNiNG: Use only the approved GME charger. The use of other types may be dangerous and will void the warranty. To Fit the battery Pack 1. Ensure that your radio is switched off. 2. A lign the slots in the battery pack with the battery guides on the back of the radio. 3. S lide the battery pack upwards as far as it will go until it ‘clicks’. slide to lock battery To Remove the battery Pack 1. Ensure that your radio is switched off. 2. Hold the radio upside-down. 3. U sing your fingernail, slide the battery catch towards the front of the radio to release the battery then slide the battery towards you. The battery pack should separate from the radio. -
Page 8: Charging The Battery Pack
Charging the battery Pack The TX685 is supplied with a desktop charger. The desktop charger will charge a fully discharged 2000 mAh battery pack to full capacity in around 7 – 8 hours. The TX6150 is supplied with a rapid desktop charger. The charger will charge a fully discharged 2200 mAh battery pack to full capacity in around 3 hours. To charge the battery pack: 1. Plug the included plug pack power supply into a standard 240 volt AC outlet. 2. C onnect the plug pack’s DC connector to the socket under the base of the desktop charger. Route the lead through the slot under the charger’s base. 3. P lace the radio with battery attached, into the cradle. The RED ‘CHG’ LED will light to indicate the battery is charging. 4. When the battery has charged, the GREEN ‘FULL’ LED will light. battery low Alert When the battery icon blinks on the radio’s display, the battery level is low and the battery pack should be recharged. If the battery is not charged, an audio tone will then sound to warn the user that the battery is almost discharged. battery usage The time taken to discharge the battery pack will depend on how you use the radio. The battery pack supplied is powerful enough for a full day’s use under average conditions. Conserving battery Power The radio has built-in power saving features to help you get the maximum amount of time between charges from your Li-Ion battery pack. If you need to operate your radio in a situation where you require maximum battery life (e.g. a remote site where there is no convenient recharging facility nearby) the following hints can greatly reduce the amount of power drawn from the battery pack. -
Page 9: General Operation
GENERAl OpERATION Power on/off Rotate the voluMe control clockwise past the ‘click’ to turn the radio on. The radio will emit a confirmation tone when it is switched on. Rotate the voluMe control counter-clockwise past the click to turn the radio off again. Adjusting the volume With the unit powered on, rotate the voluMe control clockwise to increase the volume and counter-clockwise to decrease the volume. Display lighting The LCD backlighting activates automatically whenever a key is pressed and turns off automatically after about 5 seconds. Receiving signals While the radio is not receiving signals, it will remain in standby mode to conserve battery power. When a signal is received, the LED indicator on the upper edge of the radio will light GREEN and the icon will appear on the display. Adjust the voluMe control for a comfortable listening level. If the incoming signal is encoded with a CTCSS or DCS tone matching the one set in your radio, the LED indicator will light ORANGE and you will be able to hear the signal in the speaker. If the LED indicator lights GREEN and the icon appears but you cannot hear the signal, it is likely that the incoming signal is using a different CTCSS or DCS tone to that selected in your radio (see Menu options for more details on setting CTCSS/DCS tones). If no further signals are received, the unit will return to standby mode. Transmitting To transmit, press and hold the PTT (Push-To-Talk) switch. The other radio you are talking to must be set to the same channel. Hold the radio approximately 5 to 8 cm from your mouth with the antenna vertical and speak into the built-in microphone. While the PTT switch is pressed, the LED indicator on the upper edge of the radio will light RED and icon will appear on the LCD. When you have finished speaking, release the PTT switch to receive incoming signals (it is not possible to transmit and receive at the same time). If no further signals are received, the unit will revert to standby mode. -

NoTe: The squelch sensitivity is preset in the Menu – Squelch Level setting (see Menu options for more details on setting the squelch sensitivity). Keypad lock The Keypad Lock disables the keys to prevent accidental key presses from changing the preferred settings of the radio. When the keys are locked, the Icon is displayed and all key presses are ignored except for the PTT, sQl and the Keypad unlock function. To activate the Keypad Lock press the F key (the F icon will appear) then hold the key until the radio beeps. The icon will appear on the display. To cancel the Keypad Lock, press the F key then hold the key again until the radio beeps. icon will disappear. Duplex operation Duplex operation allows the radio to transmit on a different frequency to that which it receives. This allows operation through repeater stations in your area. Repeaters automatically re-transmit your signal over a much wider area, providing greatly increased range. The Duplex mode only works on designated repeater channels 1 – 8 and 41 – 48. With Duplex selected on one of these channels, your radio actually transmits 30 channels higher than it receives. e.g. If Duplex is selected on channel 1, your radio will receive on channel 1 but will transmit on channel 31. Duplex can be enabled or disabled separately on individual channels. When Duplex is enabled on the selected channel, is displayed. The Duplex Mode is set through the Menu. Please refer to the Menu options further below. simplex/Duplex Range Comparison SCANNING Channel scanning allows you to monitor a sequence of selected channels for incoming signals. NoTe: While the radio is scanning, the Menu setting key is disabled. To select Channels for scanning 1. Press the keys to select the required channel. -
Page 11: Scanning Features
To exit the scan mode, briefly press the sCAN key again. The radio will return to normal operation. NoTe: There must be at least 2 channels stored in the scan memory otherwise the radio will not scan. scanning Features • I f a signal is received, the scan is paused allowing you to transmit and receive on that channel. During this time the icon will continue to flash to show that the scan is still active. Once the channel has been inactive for 5 seconds the scan will automatically resume. • P ressing the PTT switch while the radio is scanning will jump to the working channel allowing you to transmit and receive on that channel (the working channel is the channel the radio was on at the time the scan was activated). During this time the icon will continue to flash to show that the scan is still active. Once the working channel has been inactive for 5 seconds the scan will automatically resume. • I f the scan is paused on a busy channel that you don’t wish to listen to, press the keys to ‘skip’ over the channel and continue scanning. TiP: The Scan mode will reduce the overall battery life because the Standby (battery saver) feature is overridden. You should avoid scanning if the battery is running low and you need to conserve power. CTCSS, dCS ANd SIlENT MOdE CTCSS (Continuous Tone Coded Squelch System) and DCS (Digital Coded Squelch) are similar squelch quieting systems that allow groups of users to share the same channel without disturbing each other. The CTCSS system uses 1 of 50 low frequency tones to open and close the squelch on the radio. The DCS system is similar to CTCSS but uses 1 of 104 digital codes to control the squelch. When CTCSS or DCS is enabled on your radio, only signals that are using the same code as your radio will be heard in the speaker and the squelch will remain closed to all other signals. -
