  • Patent number: 5463368
    Abstract: In order to change a subscriber alert mode of a radio pager from an audible alert mode to an inaudible alert mode, a normally open function switch is depressed while the radio pager operates in the audible alert mode. The function switch is subsequently depressed. Following this, a timer is set to count up to a predetermined time period. A pager display exhibits a silent time duration for which the pager will operate in the inaudible alert mode if the timer counts up the predetermined time period. Subsequently, another timer is set to count up to a predetermined time period if the function switch is released. Thereafter, if the second timer counts up the second predetermined time period and if the function switch remains released, the radio pager is set to operate in the inaudible alert mode for the set silent time duration.
