ABSTRACT:
A radio apparatus, particularly a personal transceiver, includes a manual keypad for keying numerical data, read and write function keys, and a data processor. The processor is programmed to store keyed numerical data representing part of a multi-digit destination code into a storage location of a read-write memory in response to operation of the write function key and store keyed numerical data representing the address of the storage location. The stored part-destination code data are retrieved in response to successive operation of the read function key and the keyed keying numerical data representing the address of the storage location. In response to subsequent operation of the keypad keying numerical data representing an additional digit, the latter is appended to the part-destination code read from the memory to complete a full destination code.
