| Zusammenfassung: | The device has conventional display and operating controls for time-setting augmented with a switch (201) enabling the user to choose whether the alarm sound is a simple buzz or a combination of the buzzer with a sequence of audio tones from a semiconductor memory, into which the tones can be input by microphone (203) when another switch (202) is operated. The relatively narrowband buzzer signal is emitted by a loudspeaker (204) while the microphone serves also as a speaker for the audio tones. |
