How to use the online alarm clock
While you watch the clock for the airport dispatcher shift handover, set the alarm for 3:14 am and keep the remaining duties within reach. The alert marks the exact handover moment, leaving the period before 4:00 am for checking the log, noting unresolved movements, and preparing a clear briefing without repeatedly unlocking your phone.
During an overnight airport shift, another page or app may push the alarm tab into the background. Leave the browser running and return to the alarm page occasionally so you can confirm that it is still active and the volume is audible. If the browser is closed or the phone goes to sleep, the airport shift handover alert cannot sound. Use a system alarm as a backup when missing 3:14 am could delay the incoming dispatcher.
Before handing over under dim control-room lighting, lower the screen brightness enough to read the movement notes without a harsh glow. Keep the phone slightly below eye level, use the interface’s dark appearance if available, and avoid staring at the countdown continuously. Brief checks are usually sufficient while you monitor the desk, and the alarm can provide the final cue at 3:14 am.
Common questions
Does closing the browser tab stop the alarm from ringing?
The page must remain open for the 3:14 am alarm to sound. Switching tabs, minimising the window, or using another application will not end it, but closing the alarm tab or quitting the browser will.
Can the alarm ring if this tab is no longer open?
Think of the browser tab as the alarm's running space: once that tab is closed, the alarm scheduled for 3:14 am can no longer continue. It does not need to stay visible, so you may minimise the window or browse elsewhere.
Will my alarm work once I have closed the tab?
No, closing the page stops the alarm rather than leaving it active in the background. For an alert at 3:14 am, keep that particular tab open; it can sit behind other tabs or inside a minimised browser window.
Does the tab need to stay open for the alarm?
Your device will not take over the alarm after the webpage closes. The tab containing the alarm for 3:14 am needs to stay loaded until it rings, although you are free to switch windows, check another site, or minimise the browser.
