Humminbird 100 Guia Do Utilizador

HOW THE LCR-100 WORKS 
 
There are two main components to your LCR 100 installation: The transducer, which was 
installed beneath your boat, and the LCR 100 unit, mounted either in-dash or on a gimbal 
bracket. The transducer and LCR 100 communicate by means of a cable, and are powered by 
your boat's 12-volt DC battery. 
 

              

 

 
The transducer and LCR 100 use the basic principles of sonar to reveal objects beneath the 
water's surface. The LCR 100 continuously sends electronic signals to the transducer, which 
converts them to ultrasonic signals that it aims toward the bottom. Each signal travels downward 
until it strikes an object or the bottom, then immediately echoes back to the transducer. As the 
transducer receives these signals, it converts them back to electronic signals for display on the 
LCR 100 screen. 
 
The LCR 100 uses the returned signals to display a detailed underwater image, and constantly 
updates the display as you travel across the water. The display informs you of the current depth 
and reveals individual fish, schools of fish, their location, and bottom details. 
 

 

 
Easy-to-use controls on the LCR 100 allow you to set the depth range, adjust display speed and 
sensitivity, enable a fish alarm and bottom alarm, and display a "zoom" window of still more 
detailed information. 
 
 
THE HUMMINBIRD ADVANTAGE 
 
 

The LCR 100 incorporates the best of available technologies, and offers advantages you 

won't find in other depth sounders. 
 
 

The liquid crystal display (LCD) offers sharp viewing even in bright, direct sunlight, and is 

continuously lit for nighttime operation. Advanced LCD "super-twist" technology built into the LCR 
100 offers a wider viewing angle and higher contrast than ordinary LCD screens.
