OPERATING THE LCR-100 

 
 

The LCR 100 offers several functions that you can adjust with the 

front panel buttons. (Note that to select something with a button, you 
must press it fully so that you hear a "chirp" sound.) 
 

You can get acquainted with these features by actual operation, 

or when using the simulator. 
 
POWER: Press this once to turn the LCR 100 on. Pressing it again turns 
the LCR 100 off. (Any adjustments you make with other front panel 
buttons are retained, even when the unit is turned off.) When the unit is 
off, keeping POWER pressed for about 2 seconds starts the built-in 
simulator. 
 
STOP: Press this to "freeze" the display so you can study it. Press it 
again to restart the display movement. 
 
SELECT: This button is used to access the following functions for further 
adjustment: 
 
Sensitivity/Units 
Bottom Alarm 
Fish Alarm 
Zoom 
Bottom Lock 
Display Speed 
Depth Range 
 
To adjust any of these, press SELECT until the function you want appears. Each function's 
display tells you how to use the arrow buttons and ONOFF for adjustment; These functions 
should be apparent, but when first learning, you may want to refer to the following instructions. 
 
 

After you adjust any function, the display returns to its full- screen reading. 

 
NOTE: The last function you select remains "active" - that is, you can adjust it without having to 
press SELECT again. You can use this to simplify operations. 
 
 

For example, if the bottom alarm was the last function used, you can readjust the alarm 

by pressing one of the arrow buttons. Or if you often use Zoom, you can select it once, then 
switch it on and off by simply pressing ON-OFF. 
 
 

The following pages describe each function, in order of appearance as you first press 

SELECT.
