USING THE LCR400ID 
 
This section provides complete 
information on operating the LCR 400ID 
through its front panel controls. You are 
encouraged to read this information 
completely as you first learn to use the 
LCR 400ID. Doing so will ensure you 
make the most of its many features and 
functions. 
 
The first part of this section explains the 
use of the built-in practice simulator, 
which you can use to practice selecting 
functions through the front panel. The 
remaining instructions, which can be 
followed while using the simulator or in actual operation, explain each function and are 
organized according to the front panel layout. 
 
USING THE BUILT-IN SIMULATOR 
 
The LCR 400ID includes a built-in simulator that helps you learn to use your new 
equipment. The simulator displays a typical underwater scene, and lets you practice 
with the controls. 
 
The unit must be turned off before you start the simulator. To activate it, press down 
and hold the POWER button until a chirping sound begins. Release the button, and the 
built-in simulator begins displaying a typical LCR 400ID reading. 
 
You can use the simulator to learn the functions explained in the following pages, just 
as if you were getting actual on-the-water readings (but note that “Sensitivity” is 
disabled). To turn off the simulator, turn off the unit by pressing the POWER button 
again. 
 
Of course, the best way to learn the LCR 400ID is with actual use, especially in familiar 
waters. If you know what’s below and see it on-screen, you’ll quickly become an LCR 
400ID expert.
