#2 I know it so that when the timer is set, the heat is automatically switched off at the end of the baking time - apparently not here and the alarm clock is so quiet that you cannot hear it - is that correct? In addition, the oven cracks strangely when it heats up.
If only the timer (minute minder) is set, the device does not switch off automatically after the time has elapsed. A duration and / or end (time) must be set for this. Further information on this can be found in the instructions for use from page 15. The volume of the acoustic signal cannot be changed, but you can change the duration of the acoustic signal in the oven's basic settings or change its duration. However, please understand that we cannot judge noises from a distance. In general, noises or tones are perceived very subjectively, so that they are perceived differently by different people.
