An improved handheld electronic device and an associated method provide a plurality of output modes that can be selected by a user depending upon the circumstances of a given environment. The various modes include, for example, a NORMAL mode, a SILENT mode, a LOUD mode, an OFF mode, and a TELEPHONE ONLY mode. The various annunciation settings applicable to a routine are customizable within the routine. All of the annunciation settings are output settings that are in effect whenever the NORMAL mode is active on the handheld electronic device. The other modes are alternate modes that provide operational masks which, when one of the alternate modes is active on the handheld electronic device, can override certain of the output settings that ordinarily are associated with the NORMAL mode.
