The KX-TG6824 DE with 4 handsets impresses with its 1.8 inch, white backlit graphic display for very good legibility and first-class user-friendliness. The illuminated NR(Smart) key provides additional smart features. It flashes when calls are incoming or have been missed or when new messages have arrived on the answering machine. One press is all it takes to answer calls with the hands-free function already activated or to silence the integrated alarm clock for another five minutes.The integrated, extended answering machine offers 30 minutes of recording time. Forwarding and rewinding within a message is helpful for left telephone numbers or addresses. The KX-TG6824 DE can also call a previously stored phone number and play back the message when new messages are received, and thanks to night mode and caller blocking, you can decide when you are available to whom. The KX-TG6824 also has a hands-free function, a large selection of polyphonic ring melodies and a phone book for up to 120 entries and 50 in the phone number list. Noise reduction can be easily activated during the call using the NR (Noise Reduction) key and filters out disturbing noises that occur in the background of the other party.
