I've looked at the device before buying in a store. The large buttons, large display and the 3 speed dial memory I liked. That's why I bought it for my 82 year old mother in law. On the shortcut keys I have three important numbers stored for it. The operation we were able to explain to her quickly: Call: First press Speed Dial, then enter the green handset, or only phone numbers, then green receiver Hang up: Press red handset During testing it has managed it well. The very next day she complained, however, that the phone does not work and the keys are locked. The reason I have found relatively quickly: She presses the buttons very carefully and long. 1. This is fatal for the speed-dial buttons, as the long press corresponds to the programming mode. Only when the keys are pressed and released, the stored number, when held down, nothing happens appear. 2. We live in the neighboring village, if they want to call us with the phone number requires the prefix. A long press on the "0" but activates the keypad lock. Then no more input is no longer possible.
Although we explained to her that she should press the keys only briefly, but with her 82 years, she no longer gets out the. The instructions to unlock the keypad it can not implement unfortunately.
Conclusion: Absolutely not suitable for elderly with slow motion
