different species of fish have different
sonar characteristics, so it is not always
possible to distinguish fish size
between varying species. The signal
intensity is “normalized” for depth so a
small fish close to the boat does not
appear as a large fish symbol.

adds an additional piece of
information to help the user locate fish.
On selected fish symbols, the digital
depth of the designated fish is drawn
to help locate the fish vertically.
CONTROL FUNCTIONS
The 105SX uses a simple five button
keypad for all user input. Press any
button and an audible “chirp” confirms
the control input. If a button has no function or is
inappropriate for the situation, an audible “error”
is heard. The unit sounds multiple chirps.
Power. The Power button powers the 105SX up
for normal operation. When the unit is on,
POWER turns the unit off. POWER can also be
used to go directly into Simulator mode. To enter
simulator, with the unit powered off, press and
hold POWER for several seconds until a
continuous chirp is heard.
Light.
LIGHT controls the unit’s display backlight.
With the unit powered on, press LIGHT once to
turn the backlight on “high.” Press LIGHT a second time to turn the
backlight on “low,” and a third time turns the backlight off. The backlight
is very effective for low-light and nighttime operation. When the backlight
is on, the 105SX will consume more power than with the backlight off. This
is important when using the 105SX in a portable configuration powered by
a separate battery, or when powering the unit from a trolling motor battery.
