Thanks to the large, backlit screen and the extra-large buttons on the Fysic FX-7000, you can clearly see the number you're keying in. Both during the day and at night. The sound of this landline phone doesn't interfere with hearing aids, which makes this device suitable for elderly people. The device also comes with an extra-loud ringtone, which makes missing a call all but impossible. There is space for 50 contacts. Thanks to caller ID, you can immediately see if you're getting a call from one of your contacts.
