4.2 Connecting the Handset and Headset

• Connect the coiled cord to the handset and the handset port on the phone unit.
• If using a wired headset, connect it to the headset port.

4.3 Network Connection and Power

The GRP2604P supports Power over Ethernet (PoE), eliminating the need for a separate power adapter if connected to a PoE-enabled switch or injector.

• Connect one end of the Ethernet cable to the LAN port on the phone and the other end to a network switch or router.
• If your network switch supports PoE, the phone will power on automatically.
• If PoE is not available, connect an optional 5V DC power adapter (not included) to the power port on the phone and then to a power outlet.
• To connect a computer or other network device, use another Ethernet cable to connect the PC port on the phone to your device.

The phone will boot up and attempt to obtain an IP address from your network. The display will show the boot progress and then the main idle screen.
