  2. Continue holding the button through the Welcome screen.
  1. Release the button only when the blue reset screen appears.
  2. When prompted, press 1 to confirm the factory reset.
  1. The phone will reset and reboot automatically.

    • Web UI: admin
    • Desk Phone / Menu: 236446
  • You can now:
    • Connect to Wi‑Fi
    • Access settings
    • Proceed with provisioning
