To ensure an elite-sounding connection, the system employs 5.8 GHz frequency-hopping spread spectrum technology, which operates in a less-trafficked wavelength than more common 2.4 GHz signals while still maintaining the same great security, topnotch clarity, and long range. Reception is further improved by Panasonic's Voice Enhancer circuitry, which helps clarify and improve reception by producing an easy-to-hear, natural-sounding voice, making the handsets sound crisp and intelligible even at a distance from the base. Plus, 5.8 GHz frequencies won't interfere with wireless computer networks such as 802.11b or 802.11g Wi-Fi.

This phone system is also 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, in addition to such features as a prerecorded outgoing message, remote operation, toll saver, and skip-and-repeat. And don't worry about losing your messages when the power goes out, as they're stored in flash memory for later retrieval.

In addition to the Talking Caller ID, the system offers a caller ID/call waiting combo (subscription required). Caller ID lets you see who's calling before you answer the phone, while call waiting lets you know when another call is coming in. By combining the two, however, users will learn who's calling even when they're currently in the middle of a conversation with someone else. When you hear the beep, simply look at the handset's LCD display to identify the name and number. It's especially convenient when you're waiting for an important call but still have other calls to make.

The handset speakerphone, meanwhile, is a plus when dealing with automated phone systems. You can turn on the speakerphone, put down the handset while watching TV or typing, and then pick it back up when a voice finally responds. It's far more convenient than trudging all the way to the base unit to activate the speakerphone. There are lots of other uses as well, such as putting the whole family on the phone to talk to grandma or grandpa, or conducting a business call with several folks in the room.

Finally, the phone includes a couple of features that will particularly appeal to households with kids. The first is the ability to upload unlimited free recordings of your favorite songs or sounds and set them as the handset ringer. Simply connect the included audio cable to the music source and follow the instructions (max recording time is two minutes). The second is a light-up antenna that flashes when the ringer is turned off. When someone is calling, the base of the antenna will flash so you'll know the phone is ringing. The antenna will also light up when someone leaves a message on voicemail (subscription required). Users can select from blue, green, amber, or multicolor antenna lights, while subscribers to Light-Up ID can link the individual light colors to numbers in their preprogrammed phone books.

Additional features include a 50-call memory and speed dial directory accessible through the handset's three-line backlit LCD, four-way phone conferencing, dual keypads, three ringer patterns and four melody ringers, and a headset jack (headset not included) that enables hands-free communication. The KX-TG5561M measures 11.2 by 9.7 by 5.4 inches (W x H x D) and is backed by a 90-day warranty.
