USER RECORDABLE ALERT TONE
by Wendy Lim Li Hoon
OVERVIEW
User recordable alert tone is a feature to enable a pager user to implement a preferred alert tone instead of using a pre-programmed alert tone.
When a pager beeps in a public area, other pager users in the vicinity tend to be mistakenly alerted to the pager's beeping. This confusion occurs because only a few alert tones and melodies are used for alerting and, when in a crowded area with many pager users, an alert tone for one pager is not easily distinguishable from another.
With user recordable alert tone as a feature, the pager user can record melodies, tones, music or even his or her own voice, instead of having to use the pre-programmed alert tone. Thus, an incoming page with this feature activates a tone which is pre-recorded by the pager user and, therefore, can be easily distinguishable from alert tones of other pagers.
Such a feature advantageously provides record- ing and playback for a pager and enhances the pager user's personality. Furthermore, applied with voice recordings, messages are easily understood and there is, therefore, no need for the pager user to memorize alert cadences.
