The KX-TG6521 with a 20-minute answering machine offers exceptional user comfort thanks to its large 1.8-inch graphic display, easy-to-read font, well-sized buttons, and a 4-way control for easy navigation through the menu. The cordless phone also impresses with a strong basic set of features, including a hands-free function, polyphonic ringtones, 100 entries in the phonebook, and 50 in the caller list. The practical shoulder grip application prevents the handset from slipping when wedged between the head and shoulder. Excellent voice quality is ensured by the new Clear Sound technology and optimized transmission algorithms, providing crystal-clear voice transmission even in challenging conditions. Save energy with the Eco Mode: The KX-TG6521 is low-radiation and particularly energy-efficient, consuming only 0.5 watts in standby mode.
