You should also note that it is possible to have the sensitivity set too high such that reflection off of
suspended matter or air bubbles will begin to black out the display.
In the manual mode the depth scale does not change automatically. To once again activate the
automatic mode, depress the Sensitivity Auto “On/Off” switch.
5. Alarm: The LCR 2000 is equipped with an audible alarm which, when activated, will advise the
operator of the presence of fish, structure or shallow water. The alarm controls are distinguished from
the other controls by their yellow color. The alarm is activated by pushing the Alarm “On/Off” button.
When first activated, the alarm is set at five feet. The desired alarm depth can then be adjusted up or
down by pressing the increase range or decrease range. When the increase or decrease button is
pressed once, the alarm setting will change one division. If the button is held down the setting will move
as long as the button is held down. The alarm setting is indicated down the right hand side of the
display. It is possible to set the alarm anywhere between the 4 foot to the 120 foot range. When the
bottom enters the alarm range it will trigger a continuous audible signal. Fish which enter the alarm
range will trigger a short alarm. Therefore, if you want to use the alarm feature to locate fish simply set
the alarm close to the bottom and listen for the short alarm indication.
The alarm depth will adjust itself when the depth range changes from one scale to another. Thus a
depth alarm set ten feet deep while on the 15 foot depth scale will remain at ten feet deep should the
unit advance to the 30 foot scale. Note: To set the alarm with the most accuracy, set it using the lowest
scale. For example, for a ten foot alarm setting, use the 0-15 foot scale to set in ten feet exactly. Turn
off the alarm by again pushing the Alarm “On/Off” button. The alarm setting will then go to zero. If the
alarm is turned on again before the unit is turned off, it will still be set at the previous setting.
6.Display: Stop/Resume: Anytime during the operation of the LCR, the operator may “freeze” the
display by simply pushing the display “Stop/Resume” button. This feature will aid in the learning and
