The Panasonic KX Handset for TG477 Series, KX-TGA470S is an extra handset, in black, for the Panasonic TG477 phone series. A large LED light atop the handset lets you know when someone calls and is perfect for when you can't hear the ringer. An easy-to-read, extra-wide LCD display lets you see who is calling at a glance. The bigger buttons make dialing a breeze while an amplified handset volume ensures you catch every word. Plus a Tone Equalizer control actually lets you adjust bass, mid-range or treble tones in a caller's voice for maximum clarity. In addition, the Intelligent Eco Mode feature automatically lowers the power consumption when you are using the handset close to the base unit. Not only does it extend the available talk time, it's good for the environment.
