NSN CR28A/U4M000000

Quartz Crystal Unit

A item composed of a display, optoelectronic and an integral control, optoelectronic, that performs the dual function of controlling the operational mode of, and presenting numeric, alphanumeric, symbolic, or graphic characters on an optoelectronic display. For items that do not include a control device, see display, optoelectronic. For items which are designed to display quantitative information in a specific format, see indicator (as modified), and control-indicator.
