I hear other calls when using the telephone. I hear noise on the cordless handset and the keys do not work. Disconnect the telephone base from the telephone wall jack. Plug in a different telephone. If you still hear other calls, the problem is probably in the wiring or telephone service. Contact your telephone service provider. Make sure the telephone line cord is plugged in securely. There is interference during a telephone conversation. My calls fade out when I am using the cordless handset. The handset may be out of range. Move it closer to the telephone base. If you subscribe to high-speed Internet service (DSL - digital subscriber line) through your telephone line, you must install a DSL filter between the telephone line cord and the telephone wall jack. The filter prevents noise and caller ID problems caused by DSL interference. Contact your DSL service provider for more information about DSL filters. Appliances or other cordless telephones plugged into the same circuit as the telephone base can cause interference. Try moving the appliance or telephone base to another outlet. The location of your telephone base can impact the performance of your cordless phone. For better reception, install the telephone base in a centralized location within your home or office, away from walls or other obstructions. In many environments, elevating the telephone base improves overall performance. The telephone does not receive caller ID or the telephone does not show caller ID during call waiting. Caller ID is a subscription service. You must subscribe to this service from your telephone service provider for this feature to work on your telephone. Both your and the caller's telephone service providers must use equipment compatible with the caller ID service. The caller may not be calling from an area which supports caller ID. The caller ID information displays after the first or second ring. The display shows Out of range or no pwr at base. The handset may be out of range. Move it closer to the telephone base. Make sure the power cord is securely plugged into the telephone base. Use a working electrical outlet not controlled by a wall switch. 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. 33
