In the mobile phone, I then deactivated once almost all functions and the preset service numbers removed.
Despite simple operation (open - press one of the 3 direct dialing buttons - green button) and be prescribed procedure has lasted many weeks until it hinbekommt it halfway safe ("When I have to press the green button", "Do I have to before entering the secret code? "). It is sometimes the verzweilfeln.
As I foresaw these difficulties in part, I wanted to pretend an absolutely secure algorithm: Whenever the home screen (date and time) is not visible (who was accidentally phonebook, menu, or something else called), it should turn off the phone (long on the red button) and then back on again. In this way, would always be a well-defined initial state exists.
Unfortunately, the phone turns off but not so !!! Because that only works if you are on the home screen. Once you are in a submenu, the phone turns off no longer: If you press the red button for a long time (it was even often times 30 s and longer long problert), purely nothing happens. And when it snaps shut, and for example, 10 min waiting, one is after opening still at the same location. So you have to navigate back only by repeatedly pressing the red button until the start screen, before you can turn it off!
So simple it sounds, for my father sometimes makes the already an intractable problem and the statement, the red button several times to press until the home screen is visible (that may well be 12-15 times -. If eg a long displayed phone number is deleted), also does not work one hundred percent. In one way or another was once the telephone entry of the emergency pharmacy in the menu and the red button but not active. Only after confirming with the green button you could navigate back to the home screen using the red button. The problem I could only solve on my next visit to the rehab clinic. Until then, my father could not make calls, but still be called. Sometimes things happen, to which one does not even think in a dream.
Well, but apart from this strange turn-off behavior (for which I have a point deducted) I am very pleased with your phone and the device can Recommend.
