USING THE LCR
OPERATIONAL INSTRUCTIONS
In bottom lock the expanded information always comes onto the screen at the same
location. However, as the information moves across the screen and as the bottom
contour moves up or down, the displayed information will also move so that you can see
the actual bottom contour. Remember, in bottom lock, you will be seeing up from the
bottom and this expanded area will move up or down as the bottom contour changes.
When the bottom lock is activated, the LCR will change to the lowest depth range, so
that the bottom can be tracked to the maximum depth.
6. Audible Alarms: The LCR is equipped with two audible alarms, a Fish Alarm and a
Bottom Alarm.
Fish Alarm:
The LCR Fish Alarm will give a short alarm sound anytime a return is detected between
the boat and the bottom. It will not alarm on the bottom, but only on objects off the
bottom.
To activate the Fish Alarm press the Fish Alarm “On/Off” button. The indicator in the
lower part of the screen will indicate that the Fish Alarm is on. The Fish Alarm is
operational only while the LCR is in the automatic mode. See “Manual Mode” in this
section for use of the alarm in the manual mode.
The Fish Alarm may occasionally sound when no target is displayed. This can happen
when the display sweep speed is slow such that the target was detected but gone by
the time the display is updated.
To turn the Fish Alarm off, simply press the Fish Alarm “On/Off” button again.
Bottom Alarm:
The Bottom 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 he adjusted up or
down by pressing the depth set button and the increase or decrease 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 tong as the button is held down. The
alarm setting is indicated down the right side of the display. The Bottom Alarm may be
set anywhere from 4 feet to the maximum depth. When the bottom enters the alarm
range it will trigger a continuous audible signal.
The Bottom Alarm will operate both in the automatic and manual modes, however the
operation is slightly different depending on what mode is on.
