The Panasonic KX-TG5776S cordless phone system utilizes 5.8 GHz Frequency-Hopping Spread Spectrum technology, meaning that it operates on a different wavelength with much less traffic than the 2.4 GHz technology while maintaining the great security, incredible clarity and long range. Have a wireless computer network, or thinking about getting one? 5.8 GHz technology will not interfere with wireless networks such as 802.11b or 802.11g WiFi.Add Images To Your CallsThe cordless handset is designed around a 1.5" backlit LCD screen, providing space for images that you can upload to the phone via its USB port. This set includes a single handset, but the system is expandable to a total of eight, each with its own screen.All-Digital Answering SystemThis phone system is equipped with an all-digital answering system for quick, easy retrieval of crystal-clear messages. Message operation has never been easier, with up to 21 minutes of recording time, plus such features as pre-recorded outgoing message, remote operation, Tollsaver, and skip-and-repeat. And don't worry about losing your messages when the power goes out-they're stored in flash memory so they're unaffected by power failure or interruptions.Put the Phone Down While You TalkWhen you've been on hold for ten minutes, do you really need to hold the phone? Not with the handset speakerphone. Just listen along, and press a button or pick up when it's convenient. You'll think up other great uses, like letting Grandma and Grandpa listen to their new grandchild at the same time, painting your nails as you talk to your best friend, or just being able to set the phone down while you talk.
