BOTTOM LOCK 
 
5.  Using Bottom-Lock; 
 
Factory Setting: OFF 
 
Bottom-lock provides an up-close view like Zoom, except 
that in this case the zoomed view automatically moves 
up or down to stay on the bottom. To use this feature, 
select BTM LOCK and press ON-OFF. The range of the 
display is shown when Bottom-Lock is on. 
 
This is an ideal feature for finding structure or Iocating 
fish near the bottom. 
 
Remember: If Bottom-Lock is the last function selected, 
you can use the ON-OFF button to switch Bottom-Lock 
on and off without having to press SELECT first. 
 
 
DISPLAY SPEED 
 
6.  Setting Display Speed; 
 
Factory Setting: One level below maximum 
 
The LCR 400ID display is “updated” (advances across 
the screen) as you move through the water. The speed 
at which the display is updated depends on the Display 
Speed setting. To adjust it, select SPEED, and press 
the Up arrow for a faster setting or the Down arrow for a 
slower setting. 
 
In general, higher Display Speed settings provide faster 
updates, while slower Display Speeds provide more 
detailed information.
