A profile is a collection of settings that optimizes your device for a certain activity. For example, the data pages, settings, and views can appear differently when you use the device in an airplane than when you use it for hiking.

When you are using a profile and you change settings such as data fields or units of measurement, the changes are saved automatically as part of the profile.

To use profiles on your device, you must add the Profiles menu option to the main menu (Customizing the Main Menu).
