塞纳has introduced its newest line of communicators at AIM Expo.  The new line of communicators come in three configurations,SF1,SF2 and SF4.  Each communicator uses Bluetooth technology and the same low profile body.  However,每个SF通信器具有不同的功能。

极简主义的SF1是专为不需要与其他车手沟通的单人车手设计的，但想要能够连接到他们的手机，听存储的音乐，轮流收听GPS指令或接听电话。

SF2包含SF1的所有功能，但增加了与乘客进行双向通信的能力。

最后的SF阵容是SF4，它支持自行车对自行车通信多达4个车手超过3/4半径。

All SF line communicators have a new quick charge feature.  With a 20 minute charge,Sena claims the communicators will have 4 – 5 hours of battery life.  With a full charge,the SF series communicators will have approximately 13 hours of talk time.  Each communicator also features audio overlay such that music and communications can work in parallel as opposed to a single feature taking control of the unit.  So if your GPS is giving you instructions while listening to music,the music volume will be turned down but not be muted enabling you to listen to your music while still getting instructions.  Sena's free smartphone app also allows riders to configure their SF series communicators as well.
