The menu for the most important settings after a short employment therefore almost self-explanatory, in that individual deviations from the printed manual that is to get over. Callers sound clear and easy (despite a slight background noise). The handset is the slim shape well in the hand. The keys are a bit stiff and the awful ringtones (I had the other reviewers who have criticized that, subject to eccentricity in the spirit - I must ruefully withdraw); I have the ringtone completely issued to the base station and set the well-known telecom Jingle in second lowest volume on the handset - which gives an idea of well, what to expect at the Alternative ringtones (maybe that is also the Group's strategy to 'design' all other ringtones so cruel that one is almost forced to make in your own home acoustic Telekom Advertising). It is good that you can turn off the ringer by a long press of the star key easily (especially an advantage when the phone is in the bedroom and you want to sleep late on weekends). I am not a frequent and certainly not a happy phone users - I would be, I might have invested in selecting more time and money.
