CALIBRATE STEERING AND THROTTLE (cont’d)
Calibrate Steering and Throttle allows the operator to set the steering and throttle mechanisms for
optimum control during game play. Poorly calibrated player controls can reduce profits. Calibrate the

control switches to select Calibrate Steering and Throttle and press the TEST button to activate the test.
Each of the controls has a minimum analog value of 0 and a maximum of 1.0 for its full range of motion.
These numbers correspond to digital values from 0 to 255. Both sets of numbers must track correctly to
achieve accurate steering of boats. W hen properly adjusted, the digital value will be equal to the analog
value multiplied by 255. For example, a steering value of 0.5 (straight ahead) translates to a digital value
of 128, exactly half way in between left and right steering wheel limits.
