Abstract: In a housing (20) taking the form of a microtelephone, a dial-speech circuit (4), a receiver (24), a transmitter (25), a control unit (5), and a key pad (22) are accommodated. The telephone set further includes a subscriber listing (1) divided into sections (11). In each section a bar code (13) corresponding to a speed-calling number (12) is printed, and space is left free for writing in the name of a telephone subscriber and high or her telephone number (14). Disposed at one corner of the housing is an optical transmitter-receiver (21) which, together with the housing, forms a hand-held bar-code reading wand. Connected to the control unit is a memory (3) having storage locations defined by the speed-calling numbers, at each of which locations a certain telephone number (32) is stored. By using the hand-held wand to read the speed-calling number storage code in the subscriber listing, the associated telephone number is automatically dialled by the control unit.
