4 Function, Display versions
4.1 NWW-82 Main Display Two axis SOG and one axis STW
Display with corresponding distances for JLN-900 Speed Log systems.
In the top right corner two LEDs will indicate if STW or SOG is displayed.
By default SOG will be displayed in both SPEED WINDOWS if available and valid.
If SOG is not available STW will be displayed automatically if available and valid.
Generally if no valid speed is available “---“ will be displayed.
It is possible to force the NWW-82 Main Display to indicate STW by pressing the
STW button. The LED above the STW button will then be lit confirming that STW is
chosen by the user and only STW will be displayed in the SPEED WINDOWS until
the STW button is pressed/released again, i.e. LED unlit.
