A. You can store 16 half screens in memory. Once stored, the Screen Memory will remain
virtually forever. You can disconnect power from the LCR, store it over the Winter, bring it
back out in the Spring and still be able to recall stored information.

(indicated on the menu and at the lower middle of the display) the screen will automatically
split to display the screen in memory on the left side and the full depth scale information on
the right.

on, press the button. Any information previously stored in the memory location will be
erased and replaced with the new information currently being displayed on the right half of
the screen.

the present.
BUILT-IN SIMULATOR
Your LCD4x6 has a built-in simulator. This simulator will display a typical underwater scene
which can be used for demonstration or for learning how to use and understand your unit.
To activate the simulator, the unit must first be turned off. Next, push in the
two seconds, until you hear the chirping sound. Then release the button and the simulated
display will begin.
In the simulation mode all buttons and features can be used. It should be noted, however, that
increasing or decreasing the sensitivity setting will not affect the information being displayed.
CARING FOR YOUR LCR:
Since your Humminbird LCR is completely waterproof, it can be cleaned with soap and water or
hosed off after salt water use with no fear of damage to the unit or its electronics. When cleaning
the lens, it is suggested you use a chamois cloth and a non-abrasive cleaner such as Windex Do
not wipe while dirt or other gritty material is on the lens. Care should be exercised to avoid
scratching the lens. Keep chemicals such as bug repellant, ammonia or gasoline away from the
LCR case and lens.
As with any electrical instrument, do not leave your LCR on the dash board or rear window
area of the car. The sun can create extremely high temperatures which can damage the case
and internal electrical components. During extended periods of non-use, such as Winter, you
should store the LCR and other removable depth sounders in the house or garage. This will help
prolong the good appearance and operation of these instruments.
