TESTING THE INSTALLATION
After installing your Ultima, transducer, and cables, you should test the installation.
Testing should be performed on the water, since that is the only way to check your transducer's
performance.
With your boat at idle, press the POWER button until it "chirps" once to turn the unit on.
The Ultima performs a self-test on its electronics, then automatically selects the right depth range
and sensitivity level for conditions. Momentarily, you'll see the reading start to "march" across the
screen from right to left.
Increase your boat speed to ensure that you get a continuous bottom reading as the boat
moves. Your Ultima and its transducer are designed to operate at up to 120 kph. However, use
caution when operating any boat at high speed. (High-speed testing does not apply to portable
transducers with suction-cup mount)
If the Ultima performs well at idle or slow speeds, but the display is not continuous at
higher speeds, the transducer is not installed properly. Air bubbles or turbulence from the boat
hull are passing across the transducer face, blocking the transmitted signal. By following the
instructions in "Mounting the Transducer," you can make simple adjustments that should fix the
problem.
NOTE: If other problems occur, see "Troubleshooting" later in this manual for lips from the
Humminbird engineers. If you don't find the solution there, call our toll free Customer Service
Hotline.
USING THE ULTIMA
This section provides complete information on operating the Ultima through its front panel
controls. You are encouraged to read this information completely as you first learn to use the
Ultima. Doing so will ensure you make the most of its many features and functions.
The first part of this section explains the use of the built-in simulator, which you can use
to practice selecting functions through the front panel. The remaining instructions, which can be
followed while using the simulator or in actual operation, explain each function and are organized
according to the front panel layout.
USING THE BUILT-IN SIMULATOR
The Ultima includes a built-in simulator that helps you learn to use your new equipment.
The simulator displays a typical underwater scene, and lets you practice with the controls.
The unit must be turned off before you start the simulator. To activate it, press down and
hold the POWER button until a chirping sound begins. Release the button, and the built-in
simulator begins displaying a typical Ultima reading.
You can use the simulator to learn the functions explained in the following pages, just as
if you were getting actual on-the-water readings (but note that "Sensitivity" is disabled). To turn off
the simulator, turn off the unit by pressing the POWER button again.
Of course, the best way to learn the Ultima is with actual use, especially in familiar
waters. If you know what's below and see it on-screen, you'll quickly become an Ultima expert.
