I subscribe to a nontraditional telephone service that uses my computer to establish connections, and my telephone doesn't work. Make sure your computer is powered on, and your Internet is working properly. Make sure to plug your USB telephone adapter into a dedicated USB port on your computer. Do not plug into a multiple port USB hub (USB splitter) that is not powered. In a few rare instances, the USB port on your computer may not have enough power. In these instances, try using a USB hub with its own external power supply. If you are using a firewall, it may prevent access to your nontraditional telephone service. Contact your service provider for more information. ECO mode This power conserving technology reduces power consumption for optimal battery performance. The ECO mode activates automatically whenever the handset is synchronized with the telephone base. The handset shows ECO when the ECO mode activates. I accidentally set my LCD language to Spanish or French, and I don't know how to change it back to English. While the handset is not in use or is on a call, press MENU and then enter 364# to change the handset LCD language back to English. 28
