FRITZ!Fon C4 Service - Knowledge Base
Functions that can be used with base stations from other manufacturers
All FRITZ!Fon models support the DECT standard and the DECT-GAP profile. The DECT-GAP profile enables you to use cordless telephones with base stations from different manufacturers. It also covers basic functions such as the procedure for registering a telephone with a base station and establishing telephone calls. However, DECT-GAP does not define convenience functions, which means that we cannot guarantee that you will be able to use these functions when using a FRITZ!Fon with a base station from a different manufacturer. The call list, telephone book, answering machine, clock, Internet services, software update function, RSS feeds and e-mail are only available if you use a FRITZ!Box as the base station. German is selected as the menu language in the FRITZ!Fon's factory settings. Once it registers with a FRITZ!Box, it uses the language selected in the FRITZ!Box user interface as its menu language. Since the telephone's software automatically controls the language selection, the language can only be changed if the telephone is registered with a FRITZ!Box.
