Setting the correct speed
Set the displayed (current) speed using one of the following methods:
•Use the Adjust to Speed Over Ground (SOG) screen to automatically set the current speed to SOG (if available from SeaTalk). You must be running in slack tide conditions to successfully use this method.
•Manually apply a calibration factor by means of the Cal factor adjust screen, to set the displayed speed value to your best estimate of the vessel’s speed.
