[ 14 ]• DYNAMIC MEMORY USESome features in your Nokia 6310i phone, including Calendar Notes,To-Do list, WAP, Java Applications and Wallet notes, use a commonpool of memory (storage capacity) called dynamic memory. When any ofthese features are used, there is less available memory for other featureswhich are also dependent on dynamic memory. This is especially true withheavy use.For example, entering 250 calendar notes, saving multiple WAP bookmarksand entering several items in your To-do list may consume most of theavailable dynamic memory. Consequently, if you attempt to download aJava midlet into your phone, a message saying Memory Full may appear.To proceed, you would need to delete some of the items/informationoccupying the available dynamic memory.• USE THE SELECTION AND SCROLL KEYSThe left and right selection keys ( ) are positioned beneatheach corner of the display, respectively. Centered beneath both selectionkeys are the two scroll keys .Use the scroll keys for choosing items in a list, paging through menus, andso on. Use the selection keys (often referred to as “soft keys”) to open ahighlighted feature or option, to exit or “back out” of a menu, open thePhone book, and more. A selection key’s function is always determined bythe text appearing above it in the display.For example, pressthe left selection key( ) when Menuappears above it toshow the Messagesmenu.
