Up to 8 Handsets With Just One Phone Jack - You can put handsets all over your house-in your kid's rooms or even in the garage-without all the messy wiring or complicated setup. With our 5.8 GHz expandable phone systems, you don't need a phone jack for each additional handset-just one for the base unit. So start expanding and forget about all your wiring worries. Long Range, Clear Sound, Minimal Interference - Our 5.8 GHz Frequency-Hopping Spread Spectrum technology 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. Hear Who's Calling Without Getting Up - With Talking Caller ID1, you don't have to get up to see who's calling-the phone will tell you. Panasonic cordless phones are the only cordless phones to incorporate true text-to-speech technology used in conjunction with your Caller ID service. There's no need for preprogramming or any fancy setup-as long as you have Caller ID service, just plug-and-play! Now you won't be interrupted by strange calls when you're washing the dishes, eating dinner or just watching TV. Let the phone tell you who's calling, so you can decide if you want to answer it or not. Customize Your Ringer with Your Favorite Songs - This expandable phone system lets you upload unlimited free recordings of your favorite songs or sounds that you can set as your telephone ringer. All you need is the included audio cable and the music or sounds. Maximum recording time is 2 minutes. Kids Sleeping? The Antenna Will Signal You Silently! - This year, we've 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 you2). Select from blue, green, amber or multi-color options. 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 turn off the ringer, let the kids sleep, and never miss a call. Put the Phone Down While You Talk - Having 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 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.
