The LX-9 has an Auto Range feature that allows you to simply turn on the unit and begin fishing.
To enter Auto Range, press RANGE. This will open a window with 11 range options. Now use
the UP button to highlight “Auto”. Now press MENU, and the LX-9 will automatically lock into
the appropriate depth range. For instance, in 32 feet of water, the LX-9 will lock into the 40 foot
range. In 45 feet of water the LX-9 will automatically lock into the 60 foot range. Your Range
gauge will show an “A”, and the needle will be all the way to the left.
Dynamic Depth is another exclusive feature that functions similarly to the “Auto Range”, but
fine tunes your range even farther. The Dynamic Depth will maximize the space on your display
by utilizing a constantly variable range that will always be just slightly deeper than the actual
depth. For example, if you were fishing in 23 feet of water, the Dynamic Depth range will be 25
feet, if you were in 29 feet of water, the Dynamic Depth range will be 32 feet. The Dynamic
Depth range will not go shallower than 10 feet.
To
manually adjust the LX-9’s depth range, press RANGE. This will open a window with 9
range options. Now use the UP or DOWN button to highlight whichever range you would like to
be in. Your selected range will lock in as soon as the selected range has been highlighted.
IR (INTERFERENCE REJECTION)
-- The Interference Rejection system is designed to
suppress competing return signals from other sonar units being used within close proximity.
When other sonar units are causing interference to the display of the LX-9, activate the IR
feature by depressing the IR button located on the control panel of the LX-9. Interference is
indicated by unusual signals flashing or scrolling across your display.
There are 12 levels, or channels, of interference rejection. Press the IR button once to open the
IR window, now use the UP/DOWN buttons to select the desired level of IR. The correct level
of IR will be achieved when the display is clear of display clutter. In some extreme cases, clutter
will be greatly reduced but not totally eliminated.
Anytime two or more sonars are being operated in proximity to each other, there is the potential
for interference. Deep water and hard bottom will increase the likelihood that one or more of the
competing sonars will experience interference. Besides experimenting with different levels of
IR, the anglers experiencing interference can also try having their transducers set at different
levels, going to narrow cone angles, and reducing gain or sensitivity settings.
