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 and 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. The answering system does not record messages. Make sure the answering system is on. When the answering system is on, ANS ON should display on the handset and the telephone base. When the answering machine memory is full, it does not record new messages until some old messages are deleted. If you subscribe to voicemail service, change the number of rings so that your answering system answers before your voicemail service answers. To determine how many rings activate your voicemail service, contact your telephone service provider. 46
