Frequently asked questions

How do I reset the ATA to factory defaults?

Enter the keypad code #198#; the system will automatically reboot and all user‑changeable settings will be lost.

How do I set a static IP address on the ATA?

Use the keypad code #112 followed by the IP address (using * for decimal points); this disables DHCP and switches to static IP mode.
