USING THE 105SX

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.

ID+ 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

ID+ Fish Depth

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.
