Panasonic KX-TGD320E Digital Cordless Answering System with Nuisance Call Block Single (Black/Silver). Features a 1.8-inch clear vision white illuminated display for easy reading. The answering system includes a noise reduction function and a large speaker for clear playback of recorded messages. Its stable design ensures the handset fits comfortably on the base unit. The Nuisance Call Block allows you to block specified numbers, numbers with specific digit strings, or calls without numbers. DECT Security encrypts communications and periodically changes the password for high security. Radiation Free (Eco Mode Plus) cuts transmitting power to zero and keeps the base unit off until a call or handset activation. The Advanced Answering System alerts you with a sound for new messages and can send alerts to a pre-registered mobile or office phone when you're away. Includes a Baby Monitor feature (requires more than 1 handset) and a Do Not Disturb Mode (requires Caller ID subscription).
