OPERATING INSTRUCTIONS > THE SETUP MENU

Calibrate Speed

This only appears if you are using a speed-capable transducer. Calibration is required to ensure that the speed shown on your unit is accurate. Use the boat’s speedometer, a stopwatch, or a GPS device to determine your speed. If using a stopwatch, measure the distance that the boat travels in a period of time (distance / time = speed). It is recommended that the calibration take place in water having little or no current.

To calibrate the speed:

1.Highlight Calibrate Speed, and press the ENTER key.

2.Bring the boat to cruising speed, note the top speed, and then stop the boat.

3.With OK selected, press the ENTER key.

4.Using the up or down Arrow key, set the maximum speed, and press the ENTER key.

NOTE: If the boat is not moving fast enough or the speed sensor is not registering a speed, you will see Speed Too Low displayed in the selection box. With OK highlighted, press ENTER and check that the speed sensor wheel is moving or safely increase boat speed. If there is a problem with the speed sensor/unit, check the cable connections.
