Humminbird LCR 4x6 Operation Manual page 5

The use of the split screen is very easy. Whenever any of three functions, Zoom, Bottom Lock,
or Screen Memory, is turned on the screen automatically splits.
LEFT HALF OF SCREEN

SHOWS EXPANDED VIEW, IN
CASE
THIS CASE FROM 18 FEET TO
33 FEET
When Zoom is activated, for example as shown in figure 2, the left half of the screen any shows
the expanded information while the right half shows the full depth scale information. The Zoom
range can be moved up or down to search out any area. Even the depths of the upper and lower
part of the Zoom region are digitally displayed for precise location of fish and structure.
The bottom lock and screen memory work in the same way to give you the benefit of split screen
comparisons. The detailed operation of each of these functions is explained later in this manual.
TOTAL SCREEN UPDATE
Total Screen Update was invented by Humminbird engineers. You will find this unique feature
very useful and beneficial. It will allow you, when changing depth scales, for example, to totally
change the entire screen to the new depth scale. It will also allow you to ZOOM in and look at
information in much finer detail even after you have already gone over the area.
