4.1 Connecting the Phone

1. Connect the Handset: Plug the coiled handset cord into the handset port on the phone base and the other end into the handset.
2. Connect to Network: Plug one end of the Ethernet cable into the LAN port on the phone and the other end into a network switch/hub or router. If using Power over Ethernet (PoE), the phone will power on automatically.
3. Optional Power Adapter: If PoE is not available, connect a compatible 5V power adapter (sold separately) to the power jack on the phone and then to a power outlet.
4. Connect PC (Optional): If you wish to connect a PC through the phone, plug an Ethernet cable from the PC into the PC port on the phone.

4.2 Powering the Phone

The GRP2612P supports two power options:

• Power over Ethernet (PoE): If your network switch supports PoE, simply connecting the Ethernet cable to the LAN port will power the phone.
• External Power Adapter: If PoE is not available, a 5V DC power adapter (not included with this model) is required. Connect the adapter to the phone's power port and a wall outlet.

Once powered, the phone will boot up and display network and account status on the screen.
