A notification device comprises control software including a calendar-type application, which is capable of managing notification messages and where the messages are associated with at least an item of notification content and a time of notification. The method comprises the steps of: deciding to notify a user, based at least in part on a comparison between said time of notification and current time, obtaining an audio signal based on the item of notification content, and outputting the audio signal through a speaker of the portable communication device with the resulting effect of notifying the user.
