Description

Functions

MORE FLEXIBLE

Flexible control heads and accessories allow installation according to the users requirements with a cable length of up to 40m .

CLEARER AUDIO

Adopts AI noise cancellation technology to filter out background noise (such as road noise), eliminate echoes, enhance speech and reduce howling when in close proximity to the transmitting radio. With this technology, the mobile radio provides crisper and clearer audio when transmitting and receiving voice calls.

MORE RELIABLE

Improved receiver sensitivity improves audio quality in weak signal areas to provide clearer audio

RICH SCALABLE APPLICATION

Supports multiple connections through BT,and the accessory and network (Ethernet) ports. It also supports Clarity Transmission and back to back connections which will greatly facilitate your solutions.
