The D Nect system permits wireless communication between two helmets and between one helmet and a cell phone equipped with Bluetooth* technology (Note: Bluetooth is a technology that permits data and sound to be transmitted over distances without cables through a microchip that transmits over a specific radio frequency. Many latest-generation cell phones are equipped with this device and therefore capable of working with the D Nect system regardless of the type of subscription stipulated (Tim, Omnitel, etc.). For more information on Bluetooth phones compatible with the D Nect system, consult the website: www.dainese.com ). Dainese helmets are aesthetically similar to normal motorcycle helmets but house a sophisticated interphon system with a wireless communication system (Bluetooth). The entire system is contained inside the helmet, including the batteries, which can be recharged without being removed from the helmet using the battery-charger provided. The D Nect system is completely free of external connections to the helmet and connection jacks (with the exception of the battery charging jack). Dainese D Nect helmets feature an airtight multi-function button provided with l.e.d positioned outside on the shell. Jet helmet models are equipped with a completely adjustable microphone holder arm: in order to obtain the best sound quality, the microphone must be held close to the mouth.
The system is composed of new hardware that combines a miniature radio apparatus for connection between one motorcycle and another with Bluetooth 2.0 interface. The innovation of the Infinity system is provided by the fact that it permits communication between motorcycles up to 400 meters apart without using cell phones. A virtually unlimited number of people can be inter-connected in the Infinity group, and up to three can speak at the same time, whereas everyone can listen. Cell phones can also be used even during the utilization of the Infinity system: users who receive calls on their cell phones are automatically cut out of the Infinity system in order to speak in private.
