Chart Speed; Reset Xte (Only When Navigating); Di Colors - Humminbird 688ci HD DI Operation Manual

Chart Speed determines the speed at which the sonar information moves
across the display, and consequently, the amount of detail shown.
A faster speed shows more information and is preferred by most anglers;
however, the sonar information moves across the display quickly. A slower
speed keeps the information on the display longer, but the bottom and fish
details become compressed and may be difficult to interpret.
Reset XTE is available during navigation. When it is selected, the cross track
error (XTE) will be recalculated from the boat's current position to the next
waypoint in the route.
For example, when you've deviated from a route to navigate around an island,
select Reset XTE to update the unit's course calculations from the current boat
position instead of from the previous waypoint in the route.
DI Colors allows you to select which color palette you would like to use for the
Down Imaging® display.
