IN TRODUCTION
Your GME TX3510S/TX3520S/TX3540S 80 channel radio is Australian designed and built and is the most advanced UHF Citizen Band radio available. It combines the very latest in electronic hardware with the most up-to-date computer aided design and manufacturing techniques to produce an extremely compact mobile radio with outstanding specifications and performance.
Your radio is designed for unobtrusive mounting in modern vehicles. With its built-in loud speaker and extremely small size, it can be mounted in almost any convenient location.
IMPORTANT INFORMAT ION
CONCERNING UHF CB R ADIO
The use of the Citizen Band radio service is licensed in
Australia by the ACMA Radio communications (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.
The 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.
In 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.
Original 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.
The 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
When 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.
When 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.
EMERGENCY CHANNELS
The ACMA has allocated channels 5/35 for emergency use only. Channel 5 is the primary Simplex Emergency Channel. Where a Channel 5 repeater is available, you should select Duplex on CH 5.
NOTE: Channel 35 is the input channel for the Channel 5
repeater therefore Channel 35 should also not be used for anything other than emergency transmissions.
Depending 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.
The 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.
Further information and updates are available from the Australian Communications and Media Authority (ACMA) at www.acma.gov.au and the Ministry of Economic
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 your radio 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. Currently transmissions on channels 61, 62 and 63 are also inhibited and these channels are reserved for future allocation

Adjusting the Squelch level
The Squelch sensitivity level has been factory set to provide optimum performance under most operating conditions. If required, the sensitivity level can be adjusted to suit changing conditions.
To adjust the Squelch sensitivity, briefly press the Channel control (or LVL key). The channel display will show the current Squelch level setting in values from SQL-1 to SQL-9.
Rotate the Channel control (or press the the controller microphone) to change the Squelch setting. A Squelch setting of SQL-1 allows the Squelch to open on very weak signals whereas a setting of SQL-9 requires much stronger signals to overcome the Squelch. After adjusting the Squelch sensitivity, briefly press the Channel control (or LVL key) to return to normal operation.
NOTE: The Squelch level can be actively adjusted while the
radio is scanning. This allows you to tighten the Squelch in cases where an undesired weak or noisy signal is interrupting the scan.
SIGNAL METER
The signal meter indicates the relative strength of the incoming signal in numerical format. Signal strengths are displayed on the lower left of the Channel Display in values from 0 to 9. Signals above strength 9 are displayed as 9+.
NOTE: Refer to the Configuration Menu for other options
that can be displayed in this location.
TRANSMITTING
Prior to transmitting, always check the channel is not being used. This can be done by listening to the channel or by visually checking that the meter is not indicating a signal.
To transmit, press the PTT on the microphone. The will appear. Hold the microphone about 5-8 cm from your

face and speak at a normal voice level. The microphone is quite sensitive so it is not necessary to raise your voice or shout. Release the PTT when you have finished talking. The
icon will disappear.
IMPORTANT: Always listen to ensure the channel is free
before transmitting.
TIME-OUT TIMER
The radio has a built-in time-out timer that automatically limits transmissions to a maximum of 3 minutes of continuous operation. This feature is required by the ACMA to prevent accidental blocking of the frequency should your PTT become jammed or be otherwise pressed accidentally. The time-out period can be changed by your dealer.
When the time-out timer activates, the radio will beep for 5 seconds then the
symbol will flash continuously. Normal
operation will be restored once the PTT is released.
BACKLIGHTING
The Liquid Crystal Display and keys are backlit for easier viewing at night. The backlight remains on whenever the radio is switched on.
Adjusting the Backlighting
The backlight brightness and colour can be adjusted for personal preference. There are three backlight settings available.
BKLGT (Brightness setting): Provides a continuously variable brightness adjustment from very dim to full brightness.
COLOR (Colour setting): Provides a continuously variable adjustment through the full colour spectrum.
White (Whiteness setting): Controls the colour saturation of the selected colour from deep colour to white (no colour).
To adjust the backlighting;
1. Hold the Channel control (or LVL key) to select the Backlight mode. ‘BKLGT’ is displayed.
2. Rotate the channel control left or right (or press or keys) to adjust the brightness.

BANDWIDTH FILTER SETTINGS
To accommodate the blending of newer 80 channel narrowband UHF radios with the original 40 channel wideband radios, your radio has been fitted with two user selectable receiver bandwidth filters. While the use of either filter will provide superb receive audio, selecting the wideband filter while on channels 1-40 will further increase your receiver’s tolerance to older 40 channel wideband radios that might otherwise sound over-modulated or mildly distorted. Select the narrowband filter to improve the selectivity of the receiver to provide greater resistance to interference from older 40 channel wideband radios operating on adjacent channels.
To select the desired filter
1. Press and hold MENU to enter the menu.
2. Press MENU repeatedly until ‘NBFLT’ (Narrowband Filter) or ‘WBFLT’ (Wideband Filter) is displayed.
3. Rotate the Channel control (or press make the desired selection.

differences in received audio volume between stations. Generally users have compensated for this by adjusting the Volume control for each incoming signal. With the introduction of 80 channel narrowband transmissions that use lower levels of modulation, the diversity in received audio volume is likely to increase further.
Your radio is able to automatically compensate for these variations in received audio level by utilising a Dynamic Volume Control. When activated, this feature automatically compensates for variations in received audio level resulting in a constant audio output level to the speaker.
To activate the Dynamic Volume Control
1. Press and hold MENU to enter the menu.
2. Press MENU repeatedly until ‘DVCOF’ (Dynamic Volume Control Off) or ‘DVCON’ (Dynamic Volume Control On) is displayed.

VOICE SCRAMBLER
Your radio incorporates a simple voice scrambler using band inversion. The scrambler is compatible with the majority of scramblers used by other manufacturers, allowing you to enjoy scrambled communications with owners of non­GME radios. Once the scrambler has been activated your transmission and reception will only be intelligible to others using the same scrambler technology.
To enable or disable the voice scrambler
1. Press and hold MENU to enter the menu.
2. Press MENU repeatedly until ‘ENCOF’ (Encoder Off) or ‘ENCON’ (Encoder On) is displayed.
3. Rotate the Channel control (or press 

SILENT SQUELCH TAIL
The Squelch Tail is the short burst of noise that is heard in the speaker at the end of a transmission just before the Squelch closes.
To some it is a reassuring confirmation that it is their turn to transmit but in some applications it may be an annoyance especially when listening through an earpiece or headphones.
The Silent Squelch Tail function removes this Squelch Tail, reducing it to a faint click as the Squelch closes.
To enable or disable the Silent Squelch Tail
1. Press and hold MENU to enter the menu.

Duplex operation allows the radio to transmit on a different frequency to that which it receives. This allows operation through repeater stations.
A repeater station consists of a linked transmitter/receiver combination installed in a prominent location. The repeater is designed to receive signals on a designated channel and retransmit them on another channel. Repeaters are usually mounted on hills or tall buildings. The increase elevation greatly improves both the receiving and transmitting range of the repeater allowing it to receive and retransmit signals to radios that would otherwise be out of range of each other.
Normally, UHF radios transmit and receive on the same frequency – known as Simplex operation. However to communicate through repeaters, your radio must be able to transmit and receive on different channels – otherwise known as Duplex operation. Your radio is fitted with a Duplex key to allow you to operate through repeaters.
The Duplex function can only be selected on channels 1 – 8 and 41 – 48 as these are the channels that have been allocated for repeater use. When Duplex is selected, your radio receives on the selected channel (e.g. CH 1) but transmits 30 channels higher (CH 31). The repeater hears your signal on CH 31 and retransmits it on CH 1 for others to hear.
