For the past couple of months I’ve noticed a problem with my TT Adventurer shutting down during certain times. The first occasion is when the alarm goes off and I try to acknowledge it or press snooze it shuts off. The other time is when trying to set up an activity I go through sub menus and just get to the point to start the activity and it shuts off. It’s not a battery issue as it also does this even when it’s been on charge all night. Can anyone suggest what the fix is?
