OPERATIONAL INSTRUCTIONS

Zoom and Bottom Lock: You will find the Zoom feature of the LCR4000 to be a
very valuable tool. The Zoom Range is controlled by the Range Up or Range Down
buttons. Each time one of these buttons is depressed the zoom region will move one
division. If the button is held down the region will continue to move as long as the button
is held down.
The Zoom Region is indicated by the group of bars at the extreme right of the display.
This region is 7 ½ feet on the 0 to 15 ft and 0 to 30 ft scales and is 15 ft on the 0 to 60 ft
and 0 to 120 ft scales. This means that when zooming in on the 15 ft or 30 ft scales
each dot is 1 ½ inches, and on the 60 ft or 120 ft scale each dot is 3 inches.
What Zoom Does
The zoom feature on the LCR4000 will allow you to look at underwater readings in very
fine detail and with the LCR4000's Total Screen Update you have the capability to zoom
in on bottom, fish and structure, even after you have gone over the area.
How To Use Zoom
First position the Zoom
Region (See Figure 16) next
to the area that you want to
expand by pressing the
Range up or down button.
Next, by pressing the Zoom
On/Off button the Zoom will
be activated. You will notice
that the letter Z appears in the
lower right hand corner of the
display, indicating
that the
Zoom is on. You will also
notice that the entire screen
has been changed to show an expanded view of the area from the top of the Zoom
Range to the bottom of the Zoom Range. The LCR4000'S Total Screen Update feature
allows you to zoom in on an area even after you have passed over it. Figure 16 shows
two screens, one with Zoom off and one after turning Zoom on.
