ABSTRACT:
A telephone training device to be operated by children or someone without a working knowledge of telephones, uses at least one working telephone, and a memory to store a first set of numbers, a receiver to accept a second set of numbers, a comparator to compare the second set of numbers to the first set of numbers, and a tone generator. The tone generator generates one tone when the handset is removed from the telephone, a second tone when the second set of numbers is different from the first set of numbers, and a third tone when the second set of numbers is the same as the first set of numbers.
