I - Compatibility and minimum requirements
a) PC* minimum requirements
- Operating system Windows 98SE/Me/NT/2000/XP or superior;
- DVD-ROM drive (4x or superior);
- Card reader;
II - First Steps
a) GPS
- To retrieve a position you must have, at least, 3 satellites with good reception (they appear with a
red bar in the GPS window). With 4 or more satellites you will have a more precise position and an
altitude measure;
- The first time you turn on the GPS, or without using it for a few hours, the first reception will take
longer (about 5 minutes to obtain signal in some cases);
- To speed up the signal reception you must be in a wide open place and with some visible sky above
you. Walking will increase the time to retrieve the first position;
- Clouds, trees, buildings and fog will decrease considerable the quality and intensity of the GPS
signal. The errors will be higher and the system will be slower.
