Humminbird 400TX Fish Finder User Manual


 
SIMULATOR OPERATION
The 400TX contains a simulator that allows you to use the unit as
if you are on the water. The simulator is invaluable for learning
how to operate the 400TX.
There are two ways to start the simulator. If the unit is powered off,
press and hold the POWER button for approximately three
seconds until you hear a continuous chirp.
The simulator can also be started by selecting the Simulator option on the start-up screen after
you power-up the unit. When this screen is shown, simply press the DOWN ARROW until
"Simulator" is highlighted. When the screen times out, the unit will be in simulator mode.
Once the Simulator mode is selected, the next screen will allow you to
select either "down" simulator or "side" simulator. The "down" selection
simulates normal operation of the unit with the Tri-beam transducer
connected. "Down" simulator is the default setting, so if no adjustment is
made, the down simulator will be selected. The "side" simulator simulates
operation with a Wide Side transducer connected. This is an excellent way
to see if you like the way the unit works using the optional Wide Side
transducer.
When in simulator operation, the 400TX responds to control inputs as if it is in actual operation,
so feel free to experiment, or to customize the unit for your particular operation.
To exit Simulator mode, power the unit off.
FEATURE MEMORY
If your 400TX is installed with a transducer connected, any changes you make to the set-up or
User Options (see Control Functions) while in Simulator are retained in the unit's memory. This
allows you to use simulator to experiment with the various set-up options, and retain your
selected settings for normal operation.
If you are using the 400TX in Simulator when no transducer is connected, any selected options
are lost when the unit is powered off. The 400TX will return to Factory Settings, or options
selected when last used with a transducer, if no transducer is connected.
IMPORTANT A transducer must be connected to the 400TX in order to retain user settings
selected when in simulator mode. If no transducer is detected, the unit defaults to pre-selected
options when powered off.
