AccuTracking

There could be various reasons for "not tracking": poor sky view, poor coverage, battery out etc.. Unfortunately there's no way to remotely diagnose the phone.
The only way to pinpoint the cause is to get the phone and read the message on the phone screen, then look it up here: http://support.accutracking.com/kb/article/000072

Installed tracking system on other phone. I go to accutracking map. Map says that phone is in a certain area for over 24 hours when I know it is not in that area.
What do I need to do to fix this?
