Your device, running the Codan XTEND app, can connect to your radio via a Codan Envoy SmartLink ( or via another Wi-Fi router. Access to the radio can be controlled by use of a user PIN, in addition to the standard Wi-Fi security mechanisms.

In combination with the Sonim XP7700 smartphone, the app allows you to use the familiar physical PTT button as per the Envoy handset.

Up to a total of four smartphone devices, or standard Envoy handsets/consoles may be connected to your radio at once, although responsiveness and audio quality may be reduced if multiple smartphone devices are connected to your radio via Wi-Fi in an environment where there are a number of other active Wi-Fi hotspots.

Your radio must have the "15-10622 Opt Standard App" Sales Option enabled to allow use with Codan XTEND. Other features mentioned above may also be dependent on the Sales Options that are enabled in your radio.
