• High Contrast Liquid Crystal Display: Fully detailed LCD provides a visual indication of the selected channel and all selected functions at a glance. Backlit for viewing at night. • S urface Mount Technology: The very latest surface mount component types, design and assembly techniques and quality control procedures are used to ensure the highest performance and reliability. • C TCSS: A built-in Continuous Tone Coded Squelch System provides quiet channel operation.
Adjusting the Squelch level To remove Duplex from a channel The TX3220’s default squelch level has been factory set to provide optimum performance under most operating conditions, but can be adjusted to suit changing conditions if required. 1. Select the required channel 1-8. ‘DUP’ will be visible on the display. To adjust the Squelch level 2. Briefly press the DUP key. ‘DUP’ will disappear from the display accompanied by a low beep.
Signals received on the Priority Channel will have priority over those received on the other channels. 1 - 2 - 3 - 4 - 20 - 5 - 6 - 7 - 8 - 20 To Scan in Open Scan Mode: If a busy channel is found, scanning will pause on that channel to allow the signal to be heard and will remain there for as long as the channel remains busy. • To skip over a busy channel, briefly press the SCAN key twice. e.g.
Scanning in Group Scan Mode. TIME-OUT TIMER The Group Scan feature scans all the channels programmed into the scan memory, with the priority channel being scanned after every fourth channel. The TX3220 has a built-in time-out timer which automatically disables the transmitter if the PTT switch is pressed for too long. This feature prevents the channel from being blocked for long periods should your push-totalk switch become jammed or pressed accidentally.
Optional Microphone MC503B 6. If a different transmit tone is required, select it using the channel selector. Press and hold the SQL key to store the tone. 7. Now switch the radio OFF then ON again to return to normal operation. Note: To disable the sending or receiving of CTCSS tones, set either tone to 00. If both transmit and receive tones are set to 00, the CTCSS function is disabled and can not be selected.
Fitting the Radio Installation The TX3220 is supplied with a slim, slide-on 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 base. For maximum sound output from the internal speaker, we recommend the cradle be mounted above the radio to minimise any obstruction of the speaker. Slide radio fully into cradle until it clicks into place.
Removing the Microphone 1. Squeeze the rubber strain relief near the front panel to disengage the slot, and slide the strain relief back along the microphone cord. 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. Extension Speaker RED + DC POWER CONNECTION The TX3220 is designed for 13.
repeaters A repeater system consists of a linked transmitter/receiver combination installed in a prominent location. The repeater is designed to receive signals on a designated channel and re-transmit them on another channel. Repeaters are usually located on hills, mountains or tall buildings. The increased elevation greatly improves the range of the repeater beyond that of a normal base or mobile.
