You can check to find out the handset version by enabling a button sequence.Press the [P3] key and channel up button together and power on with volume dial.On my radio there is an indication of REV 1.1 Sum3625. I have no idea of what the Sum 3625 means.


Even though it is a Version 1.1. commercial radio it is compatible with the CS-F3020 Rev 1.0 software.
