INTRODUCTION POSSIBLE ISSUES Your GME TX4500S 80 channel radio is Australian designed and built and is the most advanced UHF Citizen Band radio available. Combining the very latest in electronic hardware with the most up-todate computer aided design and manufacturing techniques has resulted in a mobile radio with outstanding specifications and performance.
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. RECEIVE (RX) User Selectable Wide/Narrow Receive Filter User Programmable Receive-Only Channels: Use the radio’s front panel controls to program up to 95 of your own receive-only channels (in 5 banks of 19 channels) within the 403-520 MHz frequency range.

MICROPHONE SELECTING CHANNELS Skip/Call Channel Up Channel Down To select the required channel, rotate the Channel control. Rotate the control clockwise to select a higher channel or counter clockwise to select lower channels. The selected channel is displayed on the LCD. SQUELCH Push To Talk The Squelch is used to eliminate any annoying background noise when there are no signals present. The Squelch can be opened or closed using the Squelch control.
TRANSMITTING Prior to transmitting, always check the channel is not being used. This can be done by listening to the icon is channel or by visually checking that the not visible or the signal meter is not indicating a signal. To transmit, press the PTT switch on the icon will appear. Hold the microphone. 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.
DYNAMIC VOLUME CONTROL (DVC) To Enable or Disable the Silent Squelch Tail The modulation level of signals heard on the UHF CB band has always varied considerably resulting in noticeable 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.
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 increased 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.
beep will be heard as the channel is stored. 'PRI-2' will be displayed briefly. To Recall Priority Channel 1 1. Briefly press the PRI 1 key. The radio will immediately switch to the Priority 1 channel and 'PRI-1' will be displayed briefly. To Recall Priority Channel 2 1. Press F then briefly press the PRI 2 key. The radio will immediately switch to the Priority 2 channel and 'PRI-2' will be displayed for a few seconds.

Repeat to add or remove other channels in the scan memory. Select your Priority channel Program your Priority channels as described earlier under ‘Priority Channel’ then select which of the two Priority channels you wish to use for this Group Scan session. You must select your preferred Priority channel prior to scanning. • Press the PRI 1/PRI 2 key to use Priority channel 1. • Press F then the PRI 1/PRI 2 key to use Priority channel 2. To Begin Scanning Press the SCAN key.
the next transmission. In this way the group can continue to communicate with minimal interference to or from other users. To quickly determine which channels are currently programmed into the Net-Scan group Enabling Net-Scan 1. With the NETWORK scan group selected, briefly press the MENU key. ‘F’ will be displayed Net-Scan is normally switched off by default but can be enabled through your radio’s menu.
Net-Scan group will locate the transmission by identifying the group’s CTCSS/DCS code and open their Squelch allowing the transmission to be heard across the entire group. When the transmission ends, all radios in the group will immediately resume scanning. If a member of the group responds to the initial transmission, they will automatically re-use the same channel as long as the channel remains free of other signals.

SelCall Identification Number USING SELCALL Your radio is factory programmed with its own unique SelCall Identification Number (Ident). This number identifies your radio from others in your area. Your radio’s own SelCall Ident will be displayed for a few seconds to the left of the channel display when you first turn the radio on. You will need to make your Ident known to anyone who may need to call you using SelCall.
‘C9’ (or select ‘Id’ to change your radios own SelCall Ident). If an ALPHA label is displayed you will need to press F then ALPHA to switch to Numeric mode. 3. Press and hold the Channel control until the radio beeps. The right-hand digit of the SelCall Ident will flash. 4. Rotate the Channel control to select the required number in the flashing digit position. 5. Briefly press the Channel control again to select the next digit position. 6. Repeat steps 4 and 5 to enter all 5 digits as required. 7.
In addition to the alarm, the symbol will appear on the display along with the callers SelCall Ident or ALPHA label to inform you of the caller’s identity. the selected channel is now tagged for Quiet operation. To Remove the QUIET Tag from Individual Channels 1. Select a channel that has been tagged for Quiet operation. ‘Q’ will be displayed. 2. Briefly press F then hold QUIET until the radio beeps. ‘Q’ will disappear indicating this channel is no longer tagged for Quiet operation.
To return your radio to the Quiet mode, briefly press F then press QUIET. will re-appear on the display. Scanning in the Quiet Mode The radio will allow you to scan while the Quiet mode is active. Using this feature you can monitor a group of Quiet channels or a combination of Quiet and Open channels. To Scan in the Quiet Mode 1. Pre-select the required OS or GS Scan group (briefly press F then OS/GS). 2. Program your Scan channels as described under the Scanning section. 3.
3. Rotate the Channel control to select ‘A’ in the flashing digit position. This is the special code that will create the Group Call. 4. Briefly press the Channel control again to select the next digit position. 5. Continue entering the other 4 digits as required. The SelCall number is now ready to send. 6. Press and hold the CALL key. A long beep will be heard and the radio will transmit the SelCall Ident.

DC POWER CONNECTION MICROPHONE The TX4500S is designed for 13.8 V DC negative earth installations only (i.e. where the negative side of the battery is connected to the frame or chassis of the vehicle). There are two recommended methods of installation. Please refer to the following diagrams. The TX4500S is fitted with two microphone sockets – one on the front panel and one on the rear. The 6 pin microphone connector can be plugged into either socket.
The rear microphone cover hinges from the top. Simply lift the cover from the bottom. The cover will remain connected to the chassis. Lift microphone cover Plastic tab 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 radio OFF then ON again to reset it. NOTE: The power source should never exceed 25 V.
