Can the alarm volume be set differently from the normal "radio listening volume"? If so, is this possible for both alarm types (radio and buzzer)? In the manual I read something about "gradually louder" and there should also be a volume setting when programming the alarm (step 4). How is this to be understood exactly? Background to my question: I would like to listen to the radio at a low volume using the switch-off timer to fall asleep, but then be woken up louder in the morning. Thank you in advance for your feedback.
