Step-by-Step Installation Guide
Hardware Assembly and Placement
-
- Match the physical phone stand with the connection slots on the underside of the phone body.
- Snap the stand legs in, selecting either the steep or flat angle slot position to control screen tilt.
- Plug the long straight end of the coiled handset cord into the phone jack marked with a handset emblem.
- Insert the opposite end of the coiled cord deep into the base socket of the handset piece.
Power and Network Initialization
Method A: Wired Network with Power over Ethernet
- Connect a standard Ethernet network cable from an active office wall jack to the LAN port on the phone back
- The phone hardware will draw electrical operating power straight through the data cable if your network utilizes a Power over Ethernet switch
- The display screen will light up and begin loading the operational system automatically.
- Pass your local wired network signal through to a desktop computer terminal by linking a second Ethernet cable from the phone PC port to your computer tower.
