Online alarm clock for 2:59 am
You have just woken at 2:59 am to prepare the studio for a live broadcast with Europe, so the first job is simply getting upright and focused. Set the alarm for the time you need, then use the arrival of 3:00 am as a clear boundary between waking up and beginning the overnight setup.
While you check the run sheet or connect the audio gear, this alarm page may sit behind the browser window you are actively using. It should keep counting there, and returning to the page lets you confirm that it is still armed. Keep the browser running and prevent the computer from sleeping: otherwise, the studio alarm may not sound when your preparation time ends. Leave the volume at a level you can hear over fans, monitors, or a test signal.
Before going to bed, arrange the control room lighting so waking for the broadcast does not mean searching for switches in darkness. A low lamp near the doorway can guide you in, while a brighter desk light can be ready for reading notes once you sit down. At this hour, avoid lighting the whole studio unnecessarily; illuminate the console, cables, and any equipment you need to handle, and keep glare away from screens used during the European feed.
