Alarm clock: Switch off alarm-sound
Which button has to be pressed to switch off an alarm tone after the alarm has occurred, only the alarm tone and not the entire alarm via the =Info / Menu= button, and also not the snooze setting. But only the alarm tone so that the alarm wakes up again the next day with the Daily/Weekdays/Weekend setting.
Unfortunately, I have not yet found a way to just turn off the alarm sound on the device. Unfortunately, this is not described in the instructions.

Thanks for your help
