Another Amber Alert today. After I got up I turned on my 4290 STB to listen to Stingray music on Channel 726 and immediately got an amber alert. Interestingly, it was only in French verbally. That box is not connected to a TV. I checked our iPhone 5S (which is always turned off (in standby)) and the alert was there (in both languages) with the alert issued at 4:58 AM.
I then checked my 9865 STB and got the alert there as soon as I turned it on, but again, although the written alert was in both languages, the verbal alert was only in French. I don't think that's how it should work... I hit "exit" on the box when the message repeated a minute or so later (again still only in French verbally). I'm not aware of any "archive", but perhaps there is one. I'm sure if you search the internet you'll find discussion of the topic. As a matter of fact, the notification on my iPhone 5S "goes away" after a couple of views and I need to remember to do a screenshot if I want to revisit it.

I see that the alert was over at 8AM. Why was I still getting the alert on my Rogers boxes at 9:30?
