Humminbird 998c SI - Manual (Page 107)

97 Down Imaging™ X-Press™ Menu
Lower Range
Settings: AUTO, 10 to 1500 ft, 3 to 500 m
[International Models only]; Default = AUTO
Lower Range sets the deepest depth range that will be displayed by the unit.
Auto: The Lower Range will be adjusted by the unit to follow the bottom
automatically. Auto is the default setting.
Manual: You can adjust the Lower Range to lock the unit on a particular
depth.
will be displayed in the lower right corner of the screen to
indicate the unit is in Manual mode. Adjust the Upper and Lower Range
together to view a specific depth range, especially when looking for fish or
bottom structure.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and
Lower Range regardless of the settings entered manually.
Chart Speed
Settings: 1-10, where 1 = Slow, 10 = Fastest,
Default = 5
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.
SI Colors
Settings: Blue, Amber1, Amber2, Brown, Green,
Inverse, Gray, Green/Red, Default = Blue
SI Colors allows you to select which color palette you would like to use for
the Side Imaging® and Down Imaging™ display.
Cancel Navigation
(only when Navigating)
Settings: Press the RIGHT Cursor key and follow
screen instructions.
Cancel Navigation discards the current route and exits Navigation Mode.
This menu option will only appear when you are currently navigating a route.
This will not delete a previously-saved route.
For example, if you are fishing in 60 feet of water but are only interested in
the first 30 feet (surface to a depth of 30 feet) you should set the Lower
Depth Range limit to 30. The display will show the 0 to 30 foot range,
which allows you to see a more detailed view than you would see if the
display went all the way to the bottom.
