2. Setup
2.1 Unpacking and Inspection
Carefully remove all components from the packaging. Verify that all listed items are present. Note that a power supply is typically not included with this model and must be acquired separately if Power over Ethernet (PoE) is not available.
2.2 Connecting the Phone
- Connect the Handset: Plug the coiled cord into the handset and the designated handset port on the phone base.
- Connect the Network Cable: Insert one end of an Ethernet cable into the LAN port on the back of the phone and the other end into a network switch or router. If using PoE, this connection will also provide power.
- Connect Optional Headset: If using a headset, plug it into the dedicated headset port.
- Connect Power Supply (if not using PoE): If your network does not provide PoE, connect a compatible DC power adapter (not included) to the power port on the phone and then to an electrical outlet.
2.3 Initial Power-Up
Once connected, the phone will automatically power on and begin its boot sequence. The display will show startup information, and the phone will attempt to register with your VoIP system. This process may take a few minutes.
