Once provisioned onto Unity, the device enters constraint mode, preventing end-users from modifying any administrative settings. To adjust the Wi-Fi settings, users must perform a Factory Default Restore using the device’s hard keys.

In order to perform hard reset of the phone using keypad buttons please follow below steps:

1. Power cycle the WP820.
2. Press key 1 + key 9 immediately and hold it until the LCD shows the factory reset message.
3. Release the buttons and the phone will boot up with the default settings.
