Panasonic continues to evolve their technologies to make things better — at home, at work, at play and on the go with their line of DECT 6.0 PLUS telephones. Each model carries with it the same features and reliability you've come to expect from the Panasonic brand, but with improvements that make seeing, hearing and operating your phone simple so keeping in touch with family and friends is easier. The Panasonic 5-Handset Phone System,KXTG7875S DECT 6.0 is expandable up to six handsets and also comes equipped with Link2Cell capabilities. Link2Cell allows you to connect up to two cell phones to the base unit via Bluetooth technology. Make and receive cell phone calls on your home phone handsets without the inconvenience of losing service or being tethered to a wall outlet because your battery is running low. You can transfer your phonebook from your cell to the base (up to 3,025 names) and even set specific rings so you know which cell phone has a call coming through.
