PanasonicThis. Is. Brilliant. The Panasonic KX-TGM420 Series amplified cordless system features a voice volume up to 40 decibels (dB) to make caller voices easier to hear, and so you don’t miss a call, and the base unit can be set to ring loudly at up to 112 dB. Bright red LED visual ringers on the base unit and handset flash when there is an incoming call, and the phone is also compatible with hearing aids. But the most exciting feature has to be “Slow Talk” — which slows the speed of speech in real time and when checking voice messages.

The amplification features ensure you won’t be frustrated by missed calls or inaudible callers, and the large, well-lit and easy to use controls make the phone simple to manage. The KX-TGM420 system can be expanded with the option of up to six full-featured handsets. Calls from noisy places can be more easily heard with Noise Reduction to suppress background noise interference. Nuisance calls can be avoided with Talking Caller ID and Call Block (up to 250 numbers). The phone also includes Talking Dial and Talking Phonebook to guide you through your calls. The phone won’t let you down in a power failure, with an additional rechargeable battery in the base unit keeping you connected when the power goes out. When fully charged, both batteries provide power for up to 12 hours of use and up to 8 days standby.
