4. If the calculated speed is:
• The same as the current speed value noted during the calibration run, then the
calibration is correct at this speed, so proceed from Manual calibration step 6.
• Not the same as the indicated speed:
i.Calculate a new, corrected calibration factor, as follows
ii.Press
iii.Scroll to set the displayed calibration factor to the new calculated value.
5. Repeat Manual calibration steps 2 to 4, until the current speed value displayed
during the calibration run is the same as the calculated speed.

Speed calibration for smart transducer

When fitted, a smart (DST800) transducer is calibrated to a set of six default speeds:
• 0.5 kt, 1.5 kt, 2.8 kt, 4.8 kt, 10.6 kt and 80 kt
These values provide acceptable transducer performance in most circumstances.
However you can insert and/delete different calibration speeds, up to a maximum of
eight, to provide a range of speed values to best suit the way the boat will be used.
To do this:
1. With the Transducers Found menu displayed
(see Preliminary procedure on page 45), scroll
to the DST option.

tion page. This shows the list of speeds to
which the DST800 transducer is calibrated.
5. To change these speeds, press
the Airmar Speed Calibration menu. This gives
the following options:
• Add point. Use this to add a speed value to
the list of calibration speeds (see below).
• Delete point. Use this to remove a speed
value from the list of calibration speeds (see below).
• Factory Reset. Use this to reapply the default list of calibration speeds.
