Designed to work with the Panasonic KX-PRS120, the sophisticated Panasonic KX-PRSA10EW additional handset combines a modern design with fantastic performance to deliver a landline telephone that's a cut above the rest. Its slim, simple design will fit in with any modern interior without sacrificing comfort in your hand. The 2.2-inch colour screen features a stylish new interface that makes accessing the option you need quick and easy. Key Features: The beautiful colour display on the KX-PRSA10EW ensures that numbers and text are clear and easy to read , with the on-screen graphical interface providing a simple and intuitive experience. Large, well defined buttons make input and navigation easy. An error-correction system helps deliver clearer phone conversations with fewer interruptions, giving you outstanding sound, even when you're further away from the base. The KX-PRSA10EW also employs Noise Reduction to cut out some of the background noise from the other side of the conversation. It's great if you're talking to someone who's in a busy street or has children playing nearby as it will isolate their voice, making it easier for you to hear. You can also adjust the pitch of voices on the phone to help you enjoy conversation as if the other person were standing in the same room as you. If you have a caller ID service enabled by your service provider, the KX-PRSA10EW's Caller ID feature can convert text into speech , giving you a vocal representation of who's calling so you don't even have to look at the screen to find out who's one the other side. Incoming and outgoing call barring works in conjunction with your Caller ID service to help minimise unwanted or nuisance calls, ensuring only the people who matter to you can contact you. One Touch Eco Mode gives you a simple yet effective way of preserving power. By pressing the ECO button, signal output is greatly reduced, helping you save energy and money on your energy bills.
