CONTROL FUNCTIONS
Fish ID. The 200DX uses advanced signal processing to
further evaluate any sonar return between the surface and
the bottom. For instance a small school of Bait fish usually
appears as a dense cluster of individual dots. If the return
meets certain additional criteria, a fish symbol is assigned.
There are three different size fish symbols used to indicate
the intensity of the sonar return. While signal intensity is a
good indicator of relative fish size, 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.
The fish symbols indicate the sonar beam the fish is detected in. This gives you a
reliable indicator of side to side location of the fish relative to the boat. Fish symbols that
are hollow are detected in the wide beam and are around the boat. Solid fish symbols
represent fish detected in the narrow beam and are directly under the boat.
CONTROL FUNCTIONS
The 200DX 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 200DX 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 chime is heard.
