The KX-TG6721 convinces with its smart button on the handset and first-class user-friendliness. The Smart key flashes when the phone rings, there is something new on the answering machine or calls have been missed. One press on the Smart button is all it takes to accept calls with the hands-free function already activated or to silence the integrated alarm clock for another five minutes. The large 4.5 cm (1.8 inch) dot matrix display and 4-way navigation, as well as the new icon-based menu, make the system easy to use. The symbols allow intuitive access to all important settings and functions. Thanks to night mode and caller lock, users determine when they are available for whom. The call costs - especially for expensive service numbers - can also be reliably controlled via dial control.

The integrated answering machine now offers 30 minutes of recording time. The remote message counter on the base station - or the flashing Smart key on the handset - indicates whether new messages have been received. One press of the Smart button is all it takes to play the new messages. The cordless telephone also has a hands-free function, a large selection of polyphonic ringing melodies, 100 entries in the telephone book and 50 in the caller list. Multitasking made easy with the practical shoulder grip. The partially rubberized surface on the back of the handset prevents the handset from slipping when it is trapped between the head and shoulder. Save energy with the Eco mode: The KX-TG6721 is low-radiation and particularly energy-saving with only 0.5 watts in standby mode.
