Abstract
A selective call personal paging radio receiver has audio and visual means to alert the user when he or she receives a selective call transmission. The audio alerting means has low and high volume modes and a three position slide switch selects either the low volume, high volume, or power OFF modes. The switch also has an integral momentary contact push switch function. When the switch is moved from the OFF position to either the low or high volume mode and the push switch function is activated within a first predetermined time after the switch is moved and maintained activated for a second predetermined time, a distinctive alert sequence is generated and then the silent alert mode is entered. In the silent alert mode, the audio alerting means is disabled and the visual alerting means remains active.
