The Fish Alarm alerts you with a chirping sound
whenever the LCR 400ID detects fish (or another object
not attached to the bottom). To activate it, select FISH
ALM and press the ON-OFF button. A fish symbol
reminds you that the alarm is on.
ZOOM
4. Using Zoom;
Factory Setting: OFF
Zoom provides an up-close view. To activate it, select
Zoom and press ON-OFF. The Zoom view initially
begins at the surface; pressing the Up or Down arrow
adjust the Zoom depth. The range of the display is
shown when the Zoom is on.
The Zoom range depends on the current Depth Range:
7 ½’ in the 15’ and 30’ Depth Ranges, 15’ in the 60’ and
120’ Depth Ranges, and 30’ in the 180’ to 600’ Depth
Ranges.
Remember: If Zoom is the last function selected, you
can use the arrow button to adjust the Zoom depth or
ON-OFF to switch Zoom on and off without having to
press SELECT first.
