Abstract
System objectives and design criteria for an in-mine visual personnel paging system are discussed. Display technologies are evaluated and trade-offs leading to display selection are described. The prototype dispatcher's console, battery/receiver box, and visual display assemblies are functionally described. The report includes circuit descriptions, schematics, parts lists, and equipment cabinet drawings for the three assemblies. The report concludes with an estimate of the manufacturing cost for each assembly.
