Abstract: Embodiments of the present invention relate to an electronic device and/or program therefor configured to modify alert modes of the electronic device. Specifically, based on at least one predetermined criterion (e.g., a set of time coordinates, a calendar entry, etc.), a reduced alert mode may be activated in which the electronic device may be silenced or subject to a reduced volume. However, when a communication attempt is received on the device, the sender thereof will be identified and compared to a list of approved senders. If the sender is an approved sender, the reduced alert mode will be deactivated. In alternative embodiments, the reduced alert mode may be deactivated when an emergency call is received, and/or a predetermined number of communication attempts have been received from a single sender. In yet another embodiment, the electronic device may be placed in a heightened alert mode.
