ABSTRACT:
An alerting device, such as a radio (10), activates, responsive to the times when an information signal (12) is received, a silent alert, via a vibrator (24), during a first predetermined time period, and an audible alert, via a loudspeaker (22), during a second predetermined time period, exclusive of the first predetermined time period. A radio user can configure the priority and the duration of the silent and audible alerts. The radio (10) also detect the reception of the information signal and the intercoupling between an accessory 51 to the radio 10. Responsive to the detection thereof, the radio (10) activates the audible alert. Thus, the user gains a high degree of confidence that the radio (10) will activate the proper alert in situations having a wide range of ambient noise levels and distances of the radio relative to the user's body.
