It does not normally have a keyboard. The only control keys provided on this machine besides the power switch are the carriage return (CR) key, which provides a means of locally returning the type box to the left-hand margin, and the line feed (LF) key, which provides a means of locally feeding up the paper. SHIPBOARD TYPES Most of the teletypewriter sets used by Navy ships belong to the model 28 family of teletypewriter equipments. The model 28 equip- ments feature light weight, small size, quiet- ness, and high-speed operation. They present relatively few maintenance problems, and are suited particularly for shipboard use under severe conditions of roll, vibration, and shock. Another feature of the model 28 teletype- writers is their ability to operate at speeds of 60, 75, and 100 words per minute. Con- version from one speed to another is accomplished 124.
