I've had an ongoing issue with the alert function and settings and hopefully someone can tell me if I'm doing something wrong or whether this is just an inherit problem with the Dex.
For example: I have my low setting at 80 and if I haven't physically pushed the buttons to looked at my Bg it will alarm as soon as it drops below 80, no problem, nice early catch. But if by chance I have previously looked to see where my Bg is and it's 83 →(sideways) and even though it shows → it really is dropping slowly enough not to trigger a falling arrow. But then the Bg falls below 80 but no alarms sound. Later, sometimes as much as 30 minutes or more, I'll get an low alarm but by then I'm 50. This condition only happens when I've pushed buttons to look at Bg previously and I'm above 80. It doesn't happen if the receiver has been left alone like at night or if I'm busy (no buttons previously pushed), it alarms right when it crosses the 80 limit, (within the 5 minute sampling schedule). The situation is the same for a rising Bg.
I think it has something to do with the "snooze" setting which must trigger on when buttons are pushed but I've tried both the least snooze time of "30 min" and "None" but can't overcome this time lag of alerts. I look often during the day and this is a problem especially if I get occupied and stop looking for awhile. At night there's no problem with getting a quick alert, other than the 3 feeble vibe/beeps that never wake me without the addition of the $100 baby monitor I've had to add.
Advice welcomed, thanks,
