Abstract
In order to be able to convert a fully functional telephone, in particular a mobile telephone, into a “child's telephone” without requiring a large degree of expenditure, it is provided that, if appropriate in addition to further keys, just one of more keys for dialing a telephone number are accessible on the telephone, which further keys cause a stored telephone number to be dialed when they are activated.
