Isn't there a particular problem with alarms on the Libre 3 using the Libre 3 app?To give a different perspective on this, speaking as a school exams officer if your son is in a small room because of the alarms then it wouldn’t make any difference if it was on vibrate or just with the volume low. Vibrate can be at least as loud as a beep. Just make sure you inform your school’s exam team and they will make any necessary adjustments I’m sure. Good luck with his exams and my only comment from years of dealing with students and from doing exams myself with type 1 is to remind him to check 45 minutes before the exam so that if he’s low he can treat it and fully recover before the exam.
From what I've read elsewhere if someone wearing Libre 3 and using the Libre 3 app on their mobile phone chooses to have the alarms on, neither the alarm volume nor the alarm tone can be changed.
One is stuck with the alarm volume and alarm tone preset by Abbott.
I understand the alarms on the Libre 3 and Libre 3 app can be turned off. But that defeats the purpose of using the product.
Users of the Libre 3 and the Libre 3 app have described the Libre 3 alarms as "ear piercing" and "shrill." I have no idea if that is true, but if it is, it seems unreasonable for any other students sitting in the same room to be disturbed by such alarms.
I understand that Dexcom have built far more flexibility into the alarms on their phone app for their glucose monitoring products.
