OPERATIONAL INSTRUCTIONS
4. Automatic or Manual Mode
Automatic Mode- Each time the unit is turned on, the automatic feature is on. In the
automatic mode the sensitivity is adjusted automatically to give a good return and the
correct depth range is selected. The word Auto will appear in the lower left corner of the
display any time the unit is in the automatic mode. The sensitivity bar at the bottom of
the screen will increase or decrease automatically in deciding the amount of sensitivity
being used. In deeper water this bar will increase indicating more sensitivity. In shallow
water the sensitivity needed to achieve a good return will be less. Also, in the automatic
mode, the unit will black out the display beneath the bottom line.
Manual Mode- There are two
ways of putting the LCR in the
manual mode: (1) depress the
Auto "On/Off" button or (2)

word Auto in the lower left corner
of the display has gone off. The
operator can control the amount
of sensitivity by depressing the
(+) or (-) button. There are 15
sensitivity settings. When the (+)
or (-) button is pressed once the
sensitivity setting will change by
one division. If the (+) or (-)
button is held down the setting
will move up or down as long as
the button is held down. When
the maximum or minimum setting
