The Mark IV™ format was designed to transmit tone-only pages, to forward a single digit to a pager or to forward up to four digits to a pager depending on the way information is encoded. Multitone pagers using the Mark IV™ format can display one digit and sequentially display four digits. Pagers utilizing the Mark V™ pager provided a five-digit display and could display up to ten digits. These pagers have been used extensively within hospital private paging systems.
