Procured as a replacement for a defective landline phone. Delivery, packaging, etc. everything was ok. The commissioning was completely unproblematic. The general handling, menu navigation, etc is easy. Very specifically, it is, if you want to make settings that are not contained in the menu. Then you need the Operating Manual, because special code entries for this are necessary, as an example: the number of calls to the answering machine takes over. This could also be deposited directly in the menu.
The transfer of data from the phonebook of your old appliance only manually possible. That is not on the device but the fact that there it is no manufacturer standard.
