When compared to another additional handset from Panasonic, the KX-TGA651B, the KX-TGA393T has several advantages, such as a higher phonebook memory, and a higher redial history.
The DECT 6.0 technology of the KX-TGA393T enables the phone to have a longer range, as well as enhancing sound quality. It ensures the phone will not interfere with other wireless devices (routers, keyboards, etc) and protects against eavesdropping as well. The 100 item phonebook memory allows a user to store up to 100 names and numbers on the phone. The intercom feature allows a phone to directly call another handset that it is linked too.
