Руководство Пользователя для Humminbird 4000

 
The Humminbird LCR4000 will operate fully automatic or manual at the discretion of the 
operator. At the heart of the LCR is a  microcomputer which is making thousands of 
decisions every second. With the LCR4000'S automatic features you will quickly and 
easily learn the basics of operating your unit, and after a couple of trips on the water 
you'll be operating the LCR4000 like an expert. It is suggested that you familiarize 
yourself with each of the features and controls prior to operating your LCR4000. 
 
1.  Power: To activate the unit, depress the power “On” switch. The LCR4000 always 
comes on in the automatic mode. In the automatic mode, the unit will find the bottom by 
varying the sensitivity and selecting the proper depth range for a satisfactory return. 
Also, the display below the bottom is blacked out to make the display easier to read. 
 
To turn the unit off, depress the power “Off” switch. 
 
2.  Depth: In the automatic mode, the proper depth range is found as soon as the unit 
is turned on. As you move into deeper water and the bottom goes off the screen, the 
next deeper range will automatically be activated. Also, as you move into shallower 
water and the bottom is within about ten dots to the top of the screen, the depth range 
will automatically change to the next shallower scale.
