This product has a 1,600 meter (1 mile) bike-to-bike full-duplex intercom maximum range, includes Bluetooth stereo wireless helmet headset(s), and is designed for installation into most open-face, modular, and full-face style helmets. With the LX-B4FM you can call hands-free on your Bluetooth mobile phone, listen to stereo music or voice instructions of GPS navigation, and activate a wireless Intercom for rider-to-rider or rider-to-passenger conversation within a range of 1600 meters when four units are connected.

The FM radio tuner is built into the main unit and allows for station scanning.
Superior audio fidelity has been achieved with our high-fidelity, non-ported, and ultra-slim helmet 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. Standby time is over a week.

Just peel off the protective backing sheet of the 3Mtape and adhere the bracket onto 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 bracket mounting.
The 3M Tape mounting is of interest as an option that you may use at your own risk and responsibility, LEXINdoes not assume any responsibility for its use. 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, please adjust the direction of the microphone so that the triangular mark on the microphone is pointing toward your mouth.
Place the speakers into the
cheek pads. Push the speakers and microphone firmly against the Velcro pads.
Press the wires into the gap between the helmet liner and shell.
Note: The speaker with a shorter wire is for the left ear and the speaker
with a longer one is for the right ear, to enhance the FM radio reception as
well.
Mount the LX-B4FM main unit on
the bracket. 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, just push it up from the
bracket.

If the end unit one or unit four is disconnected, the other three keep 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 a conversation, there may be static, and eventually, the intercom will disconnect. In this case, the LX-B4FMautomatically tries to reconnect the Intercom rider every eight seconds, and you will hear high-tone double beeps until the connection is re-established.
If you don’t want to make a re-connection, press the Intercom button to stop
the attempt. For four riders to successfully communicate, we suggest
connecting the two Bridge units (red mark) that are paired using the Intercom
button and Volume–button first, then connecting them to the End units (blue
mark) that are paired by Intercom button and Volume+ 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 unit
