1. Introduction
Thank you for choosing the LX-B4FM Motorcycle 4-Way Bluetooth Conference
Intercom. This product has a 1600-meter 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 wireless Intercom
for rider-to-rider or rider-to-passenger conversation within a range of 1600 meters
when four units are connected.
The LX-B4FM is compliant with Bluetooth Specification v3.0 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.
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.
Please read this User Manual carefully before using this product.
