The KX-TS580 is a comfortable and functional phone featuring a 2-line LCD display and caller ID function. A phonebook with 50 names and numbers allows you to directly select the name you wish to call. If you activate the caller ID service with your phone company, you'll know who is calling before you pick up. The name and number of the caller will appear on the two-line LCD display, but only if they are stored in the phonebook. Returning calls to the numbers you have dialed is very easy, as the phone stores the last 20 dialed numbers. The call indicator visually informs you when a call is incoming. Thanks to the built-in hands-free feature in both the handset and the base, you can take calls without interrupting your work, which is especially useful when you need to take notes or use the keyboard.
