Portable or mobile radio which can send pre-stored messages to radios whose addresses are also pre-stored

摘要

A portable or a mobile radic 2 can communicate with other such radios (4,6), and can place calls to telephone subscribers. A permanent memory 32 in the radio 2 serves as an address book. A user interface circuit 42,44 enables a user to send pre-stored messages to radios whose addresses are also pre-stored. Other regions of the permanent memory 32 store an access code which can be used to make a DTMF telephone call. The telephone calls can be 'live dial', but may be made to pre-stored telephone numbers automatically.
