• Use the Adjust to 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.
Adjust to SOG
The Adjust to SOG screen is displayed only if SOG data is available from
SeaTalk. The current SOG is displayed in the top right of the display (12.8
in the illustration), and the current speed registered by the instrument is
shown as large figures (
12.4
in the illustration).
It is recommended that, if you are running in slack tide conditions, you
press the
reset
key for 3 seconds, to accept the SOG as the current speed.
The calibration factor is automatically re-calculated.
If you do not wish to accept SOG as the current speed, press the
timer
and
reset
keys together to select the Cal factor adjust screen.
Cal factor adjust
The Cal factor adjust screen enables you to manually adjust the
calibration factor. It shows the current calibration factor in the top right of
the display, and the current speed as large figures (12.4 in the illustration).
Use the
timer
or
reset
key to adjust the calibration factor so that the
current speed is the speed through the water.
If SOG data is available from SeaTalk, you can turn to the Adjust to SOG
screen by pressing the
timer
and
reset
keys.
Note: If neither of the above methods gives satisfactory results, carry out
the Speed calibration procedure (part of Intermediate calibration).
