I bought this phone as an extension part for Quattro Panasonic KX-TG6524GN conditioning. After setting up and connecting, it has immediately connected to the base or as registered. The manual is unfortunately close, have little experience with computers especially for older people. Have "Computer" written because the instructions were provided with signs or abbreviations that are commonly used in the above-mentioned range. However, the handling of the phone is very intuitive. The phone itself has a simple structure, without playful features (color screen, etc) but it Easy to use, perfectly adequate with large numbers and letters, so for the average consumer. For 5 star and Recommendation.
