Tip: How do you know when an offline map is ready to use?
To start downloading an offline map, from the first page of the app, touch Offline Maps. On the Offline Maps page, check the checkboxes next to the maps you want, and press OK. If you have WiFi, the maps should start downloading onto the device right away.
You can check the progress of the download by touching the black Android bar above the app, and pulling it down. This will show what the the device is doing right now. You should see an
entry, with a moving blue bar, and a caption that says
downloading [name of offline map]
When this entry disappears, the offline map has finished downloading. The Observer Pro app needs a few minutes to assimilate a newly downloaded offline map before it is ready to display it. When it is ready, it will say
underneath the name of the offline map.
(If you ever want to get rid of an offline map that is already loaded, go to Offline Maps, uncheck the map, and press OK.)
