OPERATION
The LC-507 is a sophisticated depth sounder, yet very easy to
operate. All of the main sonar controls are right on the front panel.
There are even seperate controls for each beam. Figure 13 shows the
control panel of the unit.

TURNING THE UNIT ON
Once the unit is connected to power you can turn it on.
Press the ON/OFF button. You will hear a series of short
beeps before the display shows up. To turn the unit off, press
this button again. All of your feature and menu settings will auto-
matically be saved in memory. When you turn the unit on again,
these settings will be restored.
USING THE BUILT-IN SIMULATOR
When learning the operation of the unit, it may be helpful to acti-
vate the internal simulator. This will play a short program, on the
display, that will simulate a real world situation. You can experi-
ment with all of the panel controls and menu functions and see the
results on the display.
To turn the simulator on, first make sure the unit is off. Now,
press the ON/OFF button and hold it in. You will hear the normal
series of beeps, followed by up to three more sets of beeps, about
three seconds later. Release the button after the last beep and the
simulator will start. There are three different programs. Each time
you start the simulator, a different program will start.
