Calibrate Speed

The speed sensor can be calibrated to compensate for inaccuracies. Be-
fore you change the setting, first calculate the percentage that the
speed is off. You will enter this percentage in a moment.
For example, if you figure the sensor is reading 10 percent faster than
actual speed, you will enter – 10 in the calibration window. If the sen-
sor is reading 5 percent slower than true speed, you will enter + 5 in
the window.
Perform your test in relatively calm water free of current, if possible.
(Unless, of course, you are taking the current speed into consideration
when making your calculation.) After you have a correction figure,
here's how to enter it:
1. Press
MENU
2. Enter the number you calculated earlier: press ↑ or ↓ to change the
first character (+ or –), then press → to move the cursor to the next
number and repeat until the percentage is correct, then press
is blank, indicating the alarm is turned off.
