Reduced Interference & Improved Security against Eavesdropping2.4 GHz Frequency-Hopping Spread Spectrum Technology. That's a mouthful, but what does it mean? Panasonic's technology "hops" constantly through a range of available channels to reduce interference and to provide improved security against eavesdropping. And since it is all digital technology, you get a very long range and great clarity.Digital Answering SystemThis phone system has a digital answering system for quick & easy retrieval of crystal-clear messages. Message operation has never been easier, with up to 15 minutes of recording time, plus features like 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 not affected by power failure or interruptions.Kids Sleeping? No Problem The Antenna Will Signal You Silently!This year Panasonic's found a way to shorten the handset antenna while still maintaining the long range that Panasonic customers have become accustomed to. But what's even cooler is that the base of the antenna - which lights up - will alert you to an incoming call (or a message waiting for you). The light-up indicator will flash quickly to show that you have an incoming call, and it will flash slowly to let you know you have a new message in your voice mailbox. So now turn off the ringer, let the kids sleep, and never miss a call.You can Put the Phone Down While You TalkHaving a handset speakerphone may not seem like such a big deal-until you have to call an automated phone system. By the time you press "2" and return the phone to your ear, you missed half the next option! And when they put you 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 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.Now See Who's Calling, Even if You're Already on the PhoneWe've all become accustomed to Caller ID and its ability to let us see who's calling before we answer the phone. Then there's call waiting, a beep letting us know there's another call coming in. But until now, you wouldn't know who was beeping in unless you answered it. With Call Waiting Caller ID you get the best of both worlds. Now when you get a beep, you can see who's calling before you answer.
