4. Enabling Fish Alarm;
Factory setting: OFF
The Fish Alarm alerts you with a chirping sound
whenever the LCR 3D detects fish (or other objects) above
the bottom. You can set it for large fish, large and medium
fish, or all fish.
To activate it, select FISH ALARM and press
ENTER. The alarm is initially set for large fish; press the
UP or DOWN arrow to display available settings. An on-
screen fish symbol shows when the alarm is on.
NOTE: Displayed fish sizes generally indicate
relative fish size, but different species may have different
sonar characteristics. Strength of return is corrected for
depth, so shallow fish don't appear larger than deeper fish.
5. Using Zoom
Factory Setting: OFF
Zoom provides a detailed view of a portion of the
screen image and can be used in any view. The zoom
range, or area to be enlarged, depends on the current
depth range: 10' 20', or 40'ranges are available. There are
two ways to use zoom: use the UP or DOWN arrow to
adjust the zoom range to the area to be enlarged, using
the digital range indicator in the zoom menu as a
reference, or by watching the zoom preview bars on-
screen. Pressing ENTER activates zoom. You may also
activate Zoom first, and then use the UP and DOWN
arrows to lower the zoom range to the area of interest. The
Zoom preview bars will always be present on-screen if the
zoom menu was used last. This allows adjustment of the
Zoom range when the menu is not present.
