Humminbird 141c - Manual (Page 21)

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. Additional Advanced menu choices
will be displayed throughout the menu system when you navigate to specific menus
while in Advanced Mode. 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).
