In the case of selective call receivers, such as pagers, it is common to switch between audible and silent alerts by means of a manual switch located on the exterior of the pager. The principle shortcoming of this approach is that it relies on the user to execute the manual switching. Therefore, should the user forget to switch to silent alert in a conference room scenario, an audible alert might be generated, thus disturbing all participants in the conference room or meeting. This problem can be overcome by utilizing the system shown in Fig. 1.
