To exit an application on the Akuvox C317 Series device, press "Cancel" to exit the current interface.

To perform a hard reset:

1. On the device: Go to More > Settings > More > Reset.
- Select "Reset To Factory Setting" to reset all data to factory settings.
- Or select "Reset Config To Factory Setting" to reset configurations only.

2. On the web portal: Go to Upgrade > Basic to reset the device.
