TO INITIATE ICE MODE,
simply press the
UP
and
DOWN
buttons simul-
taneously. You will now see the “
ICE
” mode indicator appear at the top of
the Showdown 5.6 Dual Beam display screen. In
ICE
mode, an internal LCD
heater is initiated. To exit
ICE MODE
and return Showdown 5.6 to normal
operating mode, press the UP and DOWN keys simultaneously. The
ICE
MODE
indicator will no longer show at the top of the display screen.
SENS (SENSITIVITY)
— The Showdown 5.6 is a highly-sensitive sonar unit
capable of reading the tiniest of solid objects below. It features a 25-level
Sensitivity function that adjusts either automatically or manually. By simply
turning on your Showdown, it will automatically select a level of sensitivity
appropriate for the given depth and signal strength. Ideally the Sensitivity
should be set at the lowest level possible to still view your lure and
surrounding fish, while at the same time "tuning out" excessive clutter in the
water column. Clutter can make reading the sonar screen more difficult.
Clutter can be caused by any number of suspended items including algae,
zooplankton, tiny bubbles, and other particles.
If you’re seeing too much clutter, simply decrease the Sensitivity level until
the clutter disappears. Conversely, if you’re not reading your lure directly
below the transducer, consider increasing the Sensitivity level.
MANUAL SENSITIVITY
— While your Showdown will automatically select an
appropriate level of sensitivity, you may wish to adjust the level yourself. To
manually adjust Showdown 5.6
SENSITIVITY
press the
SENS
button. The
“
SENS
” indicator will appear at the lower left of view-screen, along with a
number and bar indicator that displays Sensitivity level (0 to 25) at the
bottom of the screen.
With the
SENS
indicator active, press the
UP
or
DOWN
key to increase or
decrease your
SENSITIVITY
to the desired level. In most cases, you will have
the best performance with the Sensitivity set between 5 and 10.
RANGE
— The Showdown 5.6 is equipped with 6 separate depth ranges—20,
40, 60, 80, 120, and 240-feet. Regardless of the manual depth range setting,
Showdown 5.6 will always display digital depth, even if the bottom is deeper
than the bottom limit of the
RANGE
setting, (down to 240’).
AUTO RANGE
— In Auto Range mode, Showdown 5.6 will automatically lock
into the depth range appropriate to the depth of the water. For instance, in
32-feet of water, Showdown 5.6 will automatically lock in at the 40-foot
depth range. Auto Range allows you to simply turn on the power and begin
fishing.
MANUAL RANGE
— To manually adjust the Showdown’s depth range, press
the
RANGE
key. This will cause the digital depth markers to flash on-and-off,
indicating that the sonar has switched from
AUTO RANGE
mode to
MANUAL
RANGE
mode.
While the display is flashing, press either the
UP
or
DOWN
key to toggle
between depth ranges—20-FT, 40-FT, 60-FT, 80-FT, 120-FT, 240-FT. Pressing
UP
moves RANGE to the next shallower depth zone;
DOWN
moves to the
next deeper zone.
