The RG RSM 2 is a Bluetooth® remote speaker microphone designed for efficient communication. It perfectly replicates the 2 way radio system, for a smooth transition from PMR to LTE communication. It is compatible with the majority of PTT apps and, thanks to the clip on the back of the device, it can be positioned on chest or shoulder to ease up critical communication. Its 1600 mAh Lithium battery, that can be charge via USB type C interface, allows for long working shifts on a single charge.
