Four Photo Buttons with Autodial

The four empty slots on the main phone base can be fitted with pictures of the people that you contact most often, making it easy to call them without having to remember their phone numbers. Simply pick up the phone and press the picture of the person you want to call, it will then call them with no need for any further action. 

How Do I Add Photos to the Photo Buttons?

To add a photo to the photo buttons, simply print out the photos of your loved ones in a small 3 x 2cm size. After that, simply place the photo into one of the supplied transparent photo covers, and snap onto the desired buttons. Further instructions for setting each photo button's number can be found in the User Instruction Manual near the bottom of this page.

Can I Use the Memory Dial with the Additional Handset?

The additional handset doesn't feature enough room for the picture dial buttons, but it does include four lettered keys that allow you to speed-dial your favourite contacts. The letters correspond to the pictures on the main handset, making it easy to dial the correct person.
