Abstract:

A read-out of eight distinct function codes is obtained in a pager or similar device having a single two-word address code plug by creating a second, but dependent, address within the pager and transmitting one of eight possible variants of the two words of the two address codes and their complements. Two code plugs may also be used to provide two addresses with four function codes associated with each. Upon receipt of a coded address, the user is alerted, and the function code is stored in a write-over memory, available to be read-out on command unitl a new code is received. The memory can also be erased manually as desired. Display segments are scanned in sequence to conserve power, and a status check of the segments is provided at each power turn-on. Power status indication is also provided, at turn-on and at "read" command, utilizing both audio alert channels and the visual display elements.
