3.2 Initial Power On and Network Configuration

Once connected, the telephone will power on automatically. The backlit display will illuminate, and the phone will begin its boot sequence. During this process, it will attempt to obtain network settings.

• Static IP Addressing: If your network requires a static IP address, you may need to access the phone's network settings menu to manually configure the IP address, subnet mask, gateway, and DNS servers. Consult your network administrator for these details.
