User Mode (Normal or Advanced) - An Advanced Mode is provided for users who desire the
highest level of control over the Fishing System and Normal Mode for users who desire
greater simplicity and fewer menu choices. While you are in Advanced Mode, additional
Advanced menu choices will be displayed throughout the menu system when you navigate
to specific menus. Any changes made while in Advanced Mode will remain in effect after you
switch back to Normal Mode. See Setup Menu Tab: User Mode for specific instructions on
changing to Advanced User Mode.

Total Screen Update™ - when you change any menu settings that affect the Sonar View, the
view will update immediately (i.e. you don't have to exit the menu to apply the change to
the screen). For instance, by switching between "Inverse" and "Structure ID®" from the
X-Press™ Menu it is possible to alternate quickly between the two viewing methods.
