Joel 12 Report post Posted July 27, 2016 The DuraFon 1X handset has a black bezel around the LCD, the DuraFon 4X has a silver bezel, the DuraFon PRO has a green bezel, and the DuraWalkie has a blue bezel. Additionally, you can remove the battery and see the model on the serial number label. 1 Share this post Link to post Share on other sites
