Humminbird LCR 8000D manual

side of the display and moving to the left. The small gap in the zero line allows you to see movement on the display even when the bottom is not changing.

TROUBLE SHOOTING: If nothing happens when the "On" button is pushed, check your electrical connections and fuse. Also check that the red wire on the power cable is connected to the positive battery terminal and that the black wire is connected to the negative battery terminal. If these wires are reversed it will not damage the LCR. It is normal if when reversing the boat, the bottom return is lost, since air from the prop is being forced under the transducer. Remember the transducer cannot transmit through air.

TROUBLE SHOOTING: If the display comes on when the "On" button is pushed but no bottom information is seen, check that the transducer connector is securely locked to the rear of the LCR. Also insure that the transducer is completely submerged. A transducer cannot work properly in air or through air bubbles in the water.

TROUBLE SHOOTING: In very shallow water, the bottom reading might have gaps or the range might change to a deeper range. This is normal in about two feet or less. The automatic mode cannot "lock" onto the bottom in very shallow water.

TROUBLE SHOOTING: If the LCR comes on without pressing the "on" button or if you cannot turn it off by pressing the "off" button, carefully inspect the transducer cable. This condition will be seen if the outer jacket of the cable has been cut and is touching any metal piece of the boat (or if a metal BNC connector is touching metal).

Step 2

Still moving at a slow speed, begin going toward deeper water. Continue to move into deeper water until the bottom return goes off the display. The LCR will automatically change to the next deeper depth range. Notice that the entire screen is changed to the new depth range. This is the Total Screen Update feature.

Step 3

Press the depth set button and then the • button to change to the next lowest range. If the bottom is deeper than this range, the computer will automatically change back to the proper range. Remember, the depth range can be changed either up or down by pressing the depth set button and the A (increase) or * (decrease) button. You do not have to hold down the set button while pressing the • or Step 4

Press the Stop/Resume button to freeze the display. Move the Zoom Range down by pressing Zoom set and V button and position it down to the bottom of the water. Next, activate the Zoom by pressing the Zoom on button. You will see that the left side of the screen has changed to give you a much more detailed view. Notice that with the LCR's Total Screen Update you can see an expanded view of an area after you have already passed by it! You do not have to stop the display to use Zoom, but at first it is probably easier to learn this way.

With the Zoom on, move the Zoom Range up and down. This is how you can search up and down an entire area. Turn the Zoom off.

Step 5

Press the Stop/Resume button to begin normal transmitting and receiving.

Set the Bottom Alarm below the bottom by first pressing the Bottom Alarm On/Off button to turn the Bottom Alarm on. Now move the setting down by pressing the Bottom Alarm range set and then hold down the V button. When the setting is below the bottom, a continuous alarm will sound. You may want to move the setting above the bottom or you can turn it off by pressing the bottom Alarm On/Off button. Turn the Fish Alarm on by pressing the Fish Alarm On/Off button.
