Humminbird LCR 8000D - Manual (Page 26)

Notice the Fish Alarm indication on the screen. Any fish (or objects not on the bottom) will trigger
a short fish alarm sound indication.
Step 6
Press the Auto Sensitivity On/Off button to change to the manual mode. Notice that the word
AUTO in the lower left corner of the display has gone off. Also, the area below the bottom is no
longer blacked out. You can now change the sensitivity setting by pressing the manual set and
_A or * buttons. Notice that the digital bottom reading goes off in the manual mode. Note: In the
manual mode the depth range will not automatically change. The automatic depth change works
only in the automatic mode. Push the Auto On/Off button to go back to the automatic mode.
Step 7
Steps 1 through 6 have verified that your LCR is working properly. You are now ready to increase
boat speed to test the transducer installation. As you increase boat speed the LCR should give a
continuous bottom return. With a proper transducer installation your LCR will perform well at high
speeds.
TROUBLE SHOOTING: If at high speeds the bottom return is not continuous or there are gaps in
the bottom, then the transducer installation or location is such that air is going under the
transducer face. Refer back to the transducer mounting procedure for adjustments or for other
mounting options.
TROUBLE SHOOTING: If at high speed and high sensitivity setting the display begins to blacken,
then cavitation noise from the propeller is being received by the transducer. The transducer
should be moved away from the prop or to another location to reduce the cavitation noise.
TROUBLE SHOOTING: If a fault condition is displayed on the screen, turn the unit off and then
on again. If this does not clear the fault condition the unit should be returned for repair.
LEARNING TO USE SCREEN MEMORY
The operation of the LCR Screen Memory was discussed in detail earlier in this manual. By
following the steps below you will be able to easily learn how to use this unique feature of your
unit.
Step 1
Your LCR has been pre-programmed at the factory with 16 screens. These pre-programmed
screens will aid in your learning and hopefully let you have some fun, too.
Press the Mode Select Button to change from the digital depth display (in the lower right corner of
the screen) to the Memory Display (See Figure 21). If the screen number is not 1, press the
Memory Select Button (or hold it down) until 1 is displayed.
Step 2
To recall screen number 1 simply press the Memory Recall Button. The left side of the screen will
now display the screen that was pre-programmed at the factory.
Step 3
Now let's store a screen into location 1. Press the Store R (right) button. Recall screen 1 by
pressing the recall button and see that the old pre-programmed screen has been erased and has
been replaced by the information from the right half of the screen. This screen will remain in
location 1 until another screen is stored in its place.
A screen may be stored at any time, but you might find it easiest to stop the display before storing
a screen.
A screen does not have to be recalled before storing another screen in its place. For example, to
store a new screen in location 1, first use the memory select button to go to location 1. Now the
left side or right side can be stored by pressing the Store L or Store R button. The Recall Button
does not have to be pressed unless you want to see the stored information before it is erased and
replaced by the new information.
