The orange icon on the side of a folder indicates
that the approaching alarm has been set on all the
contacts contained in that folder. To set the alarms,
see the Contact Management section (par 2.7.3.4).
The orange icon associated to a contact, indicates
that it has been assigned a GPS position, a telephone
number or both. In case you forget where you saved
a contact, you can always carry out a name search.
