The Gigaset E290M Duo makes phone calls simple thanks to the large keys, the color screen, and an extra loud ring tone. You can also operate the device in the dark thanks to the key and screen backlight. The phone book has space for up to 150 contacts. Thanks to number recognition, you can immediately see when someone is calling who's stored in the phone book. You can call your favorite contacts with one push of a button via the 2 speed dial buttons. Want to do something during a phone call? If so, use the hands-free function via the loudspeaker.
