USING THE LCR 4000
OPERATIONAL INSTRUCTIONS
In bottom lock the expanded information always comes onto the screen at the same
location. However, as the information moves across the screen and as the bottom
contour moves up or down, the displayed information will also move so that you can see
the actual bottom contour. Remember, in bottom lock, the bottom always comes on the
screen at the same location but then as it moves across the screen it will move up or
down as the bottom contour changes.
When the bottom lock is activated, the LCR4000 will change to the 120 foot scale, so
that the bottom can always be tracked.

Display Speed:
The LCR4000 has a total of eight display speeds. When the unit is
turned on the display will be advancing at a medium speed. To increase the display
speed, depress the “Fast” button once or hold it down to change rapidly. An audible
sound is heard each time the speed is advanced. When the limit has been reached a
chirping sound will be heard. At this point the speed will be advancing at its maximum.
To decrease the speed, simply depress the “Slow” button until the desired advance is
reached.
The speed of the boat and the display speed will have a large effect on the way
information is displayed. You should select the fastest display speed for high speed
operation, but use a slower display speed for idle or trolling speed.
10.
Digital Bottom Reading:
The digital bottom reading is displayed in the lower left
area of the screen. This digital reading will operate while the unit is in the automatic
mode, on any depth scale or with zoom or bottom lock activated.
The digital bottom
reading will not be seen while in the manual mode.
