INTRODUCTION Your GME TX3350 80 channel radio is Australian designed and built and is the most advanced UHF Citizen Band radio available.
FEATURES TRANSMIT (TX) Individually Programmable DUPLEX function: User selectable for only those individual channels in your area that have repeaters, leaving the others free for use as extra simplex channels. SIGNAL PROCESSING Digital Signal Processing: Measures, filters and compresses standard analogue audio signals and converts them into digital format. Allows advanced RF and audio processing techniques to be applied to maximise the radio’s performance.
TELEMETRY CHANNELS GENERAL OPERATION ACMA regulations have allocated Channels 22 and 23 for telemetry-only applications and have prohibited the transmission of speech on these channels. Consequently the TX3350 has a transmit inhibit applied to channels 22 and 23. In the event additional telemetry/telecommand channels are approved by the ACMA, these channels shall be added to those currently listed where voice transmission is inhibited.
FUNCTION KEYS SQUELCH There are several keys beneath the microphone controller’s display that have dual functions. Their primary functions are printed on a black background and their secondary functions are printed on a white background. The Squelch is used to eliminate the background noise when there are no signals present. The TX3350 features a preset Squelch system.
very strong signals to open the Squelch. The factory default is SQL-3 which generally provides reliable Squelch operation for most applications. To select Duplex: 1. Select the required channel 1-8 or 41-48. To adjust the Squelch sensitivity 2. Briefly press the key then press the key. will appear on the display accompanied by a high beep. 1. Briefly press the key. ‘SQL-X’ will be displayed where X is a value from 1 to 9. To remove Duplex from a channel LEVEL 2.
MENU To adjust the Squelch sensitivity from the Menu The Menu provides a convenient way to customise your radios settings. The following Menu options are available. 1. Press and hold the key for several seconds. The radio will enter Menu mode and ‘SQL’ will be displayed. MENU ITEM FUNCTION AVAILABLE SETTINGS SQL Adjust Squelch Level SQL--1 TO SQL--9 CTCSS Set CTCSS or DCS Code CTCOF 2. Press the or keys to adjust the Squelch value. 3. To exit, press and hold the Menu to time out.
The TX3350 can also be set to display a battery meter instead of the signal meter. The battery meter displays the voltage of the connected power source with a resolution of 0.1 V. The Signal Meter is selected by default. To switch between Signal Meter and Battery Meter: 1. Press and hold the key for several seconds. The radio will enter Menu mode. 2. Press the key repeatedly until ‘S-MET’ (S Meter) or ‘BATT’ (Battery) is displayed. 3. Press the or keys to select the required option. 4.
4. When finished, press and hold the the Menu to time out. key or wait for PRIORITY CHANNEL The Priority Channel feature allows you to store one channel as a Priority Channel that can be instantly recalled at the press of a key. This can be used to provide instant access to your working channel or your local repeater channel. To store a Priority Channel 1. Select the required channel. LEVEL 2. Briefly press the key then press and hold the key.
3. To see the actual sub tone instead of the tone label, briefly press the key. For CTCSS tones the tone frequency will be displayed in Hz. For DCS codes the code will be displayed.

Open Scan Allows any of the installed channels to be scanned for activity. If a busy channel is found, scanning will pause to allow the signal to be heard. Once the channel has been clear for 5 seconds, scanning will resume automatically. 1-2-3-4-5-6-7-8 3. S elect the required channel by using the or keys • I f is visible to the right of the channel number, the selected channel is already in the scan memory. • I f is not visible, then the selected channel is not in the memory. e.g.
To talk on your working channel while the radio is scanning, simply press the PTT. Scanning will pause and your radio will switch to your working channel allowing you to transmit and receive on that channel. When your conversation has finished and the channel has been clear for 5 seconds, scanning will resume. Once there has been no activity on any channel for 5 seconds, the radio will resume scanning.
NOTE: In Group Scan mode you can also treat the Priority Channel as a nuisance channel and remove it from the scan session, but if you do, you will no longer be monitoring the Priority Channel while scanning. However if you press the PTT you will still be taken straight to the Priority Channel when required to converse on that channel. After your conversation has finished the scan will continue without the Priority Channel included.
THE QUIET MODE Your radio can be set to monitor signals on a busy channel but remain quiet unless it receives its own SelCall Ident. In this way, you won’t be disturbed unless someone calls you. When your SelCall Ident is received, the Quiet mode is deactivated and an alarm sounds to alert you to the call. You can then converse normally on the channel. To use the Quiet mode, refer to the Quiet mode section further below. Note that activating the Quiet mode is not mandatory for SelCall operation.
LABELLING YOUR SELCALL IDENTS LEVEL 3. Press and hold the key until the radio beeps. The right-hand digit of the SelCall Ident will flash. 4. Press the or keys to select the required number in the flashing digit position. 5. Briefly press the digit position. LEVEL key again to select the next You can label each SelCall Ident using a 5 character name to make it easier to identify callers.
The following characters are available: A B C D E F G H I J K LM N O P Q R S T U V W X Y Z Setting up QUIET mode 0 1 2 3 4 5 6 7 8 9 SPACE * Repeat the steps above to add ALPHA labels to other SelCall Idents currently stored in memory. To exit the mode, briefly press the CALL button (or simply wait 10 seconds and the Call function will time out). The radio will return to normal operation. To display the Alpha labels of incoming SelCalls, the radio should be left in Alpha mode.
Receiving signals in QUIET mode Receiving signals while scanning in QUIET mode • If a normal signal is received on an Open channel (one that is not tagged with ‘Q’) the signal will be heard in the usual way. • If a normal signal is received on an open channel, scanning will pause while the channel is busy and will resume scanning 5 seconds after the channel becomes clear. (If you were scanning in Group Scan mode, the radio may switch between the open channel and the Priority channel – this is normal).
To achieve this, the 10 radios you are calling must be programmed with sequentially numbered SelCall Idents. e.g. 1 4530, 14531, 14532, 14533.. -->, 14539 Transmitting the SelCall Ident 14531 will only activate the alarm in the radio with the SelCall Ident of 14531. However transmitting 1453A will activate the alarms in all radios with Idents 14530 through 14539 (a total of 10 radios).
Noise suppression INSTALLATION The TX3350 main unit is supplied with a slim, U-shaped mounting cradle. The cradle can be screwed or bolted in any convenient location in your vehicle (under or above the dash, on the centre console, etc.) using the mounting slots provided in the cradle. The TX3350 contains a built-in speaker, and should be installed in a convenient location in the vehicle’s cabin as the radio’s loud speaker.
Mounting the cradle Fitting the radio The mounting bracket can be oriented with the arms extending either forward or backwards to adjust the position of the front panel with reference to the mounting point. Fit radio into cradle and tighten gimbal knobs. Label Once the orientation of your radio is confirmed, you can fit the GME model label. Simply remove the backing tape and press into the recess on the front panel. Fitting the microphone The microphone uses an 8 pin plug and socket.
Removing the microphone Radio turns OFF with the ignition switch: 1. Slide the rubber boot back along the microphone cord. Connect the radio's negative (black) lead to the vehicle's chassis, or if preferred, directly to the battery's negative terminal. 2. Squeeze the plastic tab on the microphone plug towards the plug to unlock it while gently pulling the plug outwards. If the plug does not come out easily, the tab has not released correctly and should be squeezed again.
If the overvoltage warning appears you should switch your TX3350 OFF and disconnect it from the power source before locating the cause of the trouble. Once the high voltage warning has been triggered and you have fixed the source of the problem, you will need to switch the TX3350 OFF then ON again to reset it. The power source must not exceed 25 volts otherwise permanent damage may occur to your radio, which may not be covered by the manufacturer’s warranty.
