Calling is breeze with the Gigaset DL580, even if the years are starting to add up. If you have a hearing aid, you can use the device without hearing white noise. Turn up the sound to extra loud, so you can hear everyone you call. The ringtone can also be set to extra loud, and a warning light will flash when the phone rings. You won't miss a call again this way. The 4 quick keys allow you to call your favorite contacts or the emergency number by pressing one button. Of course, looks matter too. That's why the keys are extra large and the illuminated display has a high contrast. This allows you to see exactly what you're doing and prevents you from calling a wrong number.
