If they are pressed, a chirping sound will indicate that these functions cannot be changed while
display is stopped. All other functions, such as Zoom and Depth Scales, are active with the display
stopped. When the “Stop/Resume” button is pressed again the unit will resume reading at the
immediate point at which the boat is sitting in the water.
7. Alarm: The LCR3000 is equipped with an audible alarm, which when activated will advise
the operator of the presence of fish, structure or shallow water.
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 be
adjusted up or down by pressing the depth set button and then the increase
(upper arrow sign) or decrease (lower arrow sign) button.
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 (se fig. 13). It is possible to set the alarm anywhere
between the 4’ to the 480’ 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 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 at ten feet while on the 30 foot depth
scale will remain at ten feet deep should the unit advance to the 60 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 0-30 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.
