Corded large-button telephone with 6 photo memory slots, audio boost, and extra loud ringtones, along with a large ringtone display. Compatible with hearing aids. One-touch audio boost provides +40 dB extra loud volume in the earpiece for effortless conversations, with adjustable ringtone volume up to 90 dB and a large visual ringtone display so you won't miss a call. Six convenient photo memory slots allow you to program the phone numbers of your closest family members, friends, or your doctor, enabling you to call them with the push of a button. It’s easy to identify the person you want to call by their photo. The large keypad with big buttons makes dialing easier for clumsy hands, and ten speed dial numbers allow you to store phone numbers of relatives. You can adjust the ringtone volume in three levels: low, loud, or off, and adjust the earpiece volume when you need to increase or decrease the sound, as well as the microphone volume to adjust the transmitted volume. It works without batteries or power supply and can be connected directly to the box, digital router, hub, or telephone line.
