Introduction

Thank you for choosing the LX-FT4 Motorcycle 4-Way Bluetooth Conference Intercom. This product has a 2,000 meter (1.2 miles) bike-to-bike full-duplex intercom maximum range, includes Bluetooth stereo wireless helmet headset(s), andis designed for installation into most open-face, modular, and full-face style helmets. With the LX-FT4 you can call hands-free on your Bluetooth mobile phone, listen to to music or voice instructions of GPS navigation, and activate a wireless Intercom for rider-to-rider or rider-to-passenger intercom talk within a range of 2,000 meters (1.2miles) (if four units are connected). The LX-FT4 is compliant with Bluetooth Specification V4.0 supporting the following profiles: Headset Profile (HSP),  Hands-Free Profile (HFP), and Advanced Audio

Distribution Profile (A2DP). It supports universal pairing with most Bluetooth headsets on the market. The user can activate Siri or S-Voice from the main unit for voice dialing and other voice commands. The FM radio tuner is built into the main unit and allows for station scanning and station preset. Superior audio fidelity has been achieved with our high fidelity, non-ported, and ultra-slim helmet HD speakers. This headset also provides the industry’s best combination of wind and ambient noise reduction with the miniature boom microphone. The main unit is powered by a rechargeable lithium-ion/polymer power cell that provides 10-15 hours of active use from a full charge, and a standby time of one week.

Package Contents

• LX-FT4 Main unit
• Stereo HD Speaker with Interchangeable Microphone for Open Face Helmet or Full Face Helmet
• USB Charging Cable
• Mounting Bracket & 3M Double Sided Tape
• Boom microphone Holder
• Speaker Pad
• Allen Wrench
• User Manual

Installation Instructions
Mount the bracket between the internal padding and external shell of the helmet, and tighten the two screws between the bracket and clamp plate by using the Allen wrench.

Note: Depending on the size and shape of your helmet, you may need to change the thickness of the rubber pad between the clamp plates. You can find two extra rubber pads in the box. To increase the overall thickness, attach the thinner one to the original rubber pad or replace the original rubber pad with the thicker one.

If have any problems with mounting the bracket, you may use the 3Mtape to adhere it to the helmet. Just take off the rubber pad from the bracket, and peel off the protective backing sheet of the double-sided 3M tape. Remember that the white side adheres to the bracket and the red side adheres to the helmet. Press for 15 seconds and allow the glue to dry for 24 hours.

Note : Even though the 3M Tape mounting is provided for convenience, LEXIN recommends using the mounting bracket. The 3M Tape is red as an option that you may use at your own risk. LEXIN does not assume any responsibility for use of it. Locate an area in the nose section just to the left of the center to mount the button microphone for full helmets. Place the button microphone on the velcro pad and connect it to the connector of the headset.

If you are installing an open-face helmet, attach the microphone to the velcro pad, and adjust the direction of the microphone so that the triangular mark on the microphone is pointing towards your mouth. Use the boom microphone holder to fix the microphone if necessary.

Place the speakers into the helmet’s inner padding. Push the speakers and microphone firmly against the Velcro pads. If the helmet has deep ear pockets, you can use the provided spacers to place the speakers closer to your ears. Press the wires into the gap between the helmet liner and shell.

Note: The speaker with the shorter wire is for the left ear and the speaker with the longer wire is for the right ear. Mount the LX-FT4 main unit on the bracket. Attach the top first, then slide the main unit down onto the bracket until it clicks firmly into the bottom portion of the bracket.

To remove the main unit from the bracket, press the top part of the bracket and take it out.

To disconnect all, simply click the Jog Dial on both unit two and unit three.

Note: To maximize ef active intercom range, keep in mind that each unit is like a link in a chain – to maximize communication range keep the chain in the order the links are connected. unit one or four should always either lead or follow, with units two and three in the middle in the correct order.
Either one: two: three: four, or four: three: two: one.

Note
You will hear a beep sound when you start an intercom talk, it may take a few seconds to connect the other units, please wait till both units are connected to talk. If bridge unit two and bridge unit three are disconnected, then the group will be disconnected. If end unit one or unit four is disconnected, the other three stay connected.

If one unit has lost connection with another, the two units on the same channel are still connected. Just follow the above connecting instructions to reconnect the other disconnected unit when it is back in the intercom range. If one intercom rider goes out of range during an intercom talk, there may be static, and eventually, the intercom will disconnect. In this case, the LX-FT4 automatically tries to reconnect the intercom rider every eight seconds and you will hear high-tone double beeps until the connection is reestablished. If you don’t want to connect, press the Jog Dial button to stop the attempt. For four riders to successfully communicate, we suggest connecting the two Bridge units that are paired using the B button first, then connecting them to the end units that are paired by the A button.

Since unit two and unit three act as a ‘bridge’ in the chain, we suggest keeping them within the stated intercom range to maintain continuous communication. Tips: To save battery power, disconnect the intercom units if you do not need to talk. Important: The Bridge unit cannot be connected to a Bluetooth device (phone or GPS) while it is being used as an Intercom Bridge.
