Block Bothersome Callers With a dedicated Call Block button on each handset, it's easy to block telemarketers, robocalls and other unwanted caller numbers. One button registers up to 250 caller numbers — even while the phone is ringing or while you're talking or listening. Bi-lingual Talking Caller ID When the phone rings on one side of the room and you're on the other, Panasonic's advanced Talking Caller ID in English and Spanish and Text ID tells you who is calling with text-to-speech announcements from speakers in the base unit and handsets. Beyond Intercom Wake kids for school in the morning and let everyone know when dinner is ready in the evening with Panasonic's exclusive Voice Paging. More than a conventional intercom, VP makes it easy to send clear, simultaneous announcements to every handset in the house, even when family members don't respond. Power When the Power Goes Out Included rechargeable backup batteries keep you connected when the power goes out. With a fully charged handset in the base unit, you'll have power for up to 12 hours talk time and 7 days standby for calls using other cordless handsets in the house. Talking Low Battery Alert Now, when any of your handsets are running low on power, the handsets tell you. And as an added convenience, a large, high-visible battery status icon on the handset LCD lets you know as well. Hear Calls from Noisy Places Whether someone is calling from a busy city street or from a raucous room, Noise Reduction automatically suppresses background interference while also enhancing voice tones for clearer, more comfortable conversations. Large Backlit Handset Display Large 1.8-inch high-contrast white backlit handset LCDs, enlarged, easier to see and use dial keys, and smart function control buttons make home and home office call management quicker and more convenient for everyone.
