Description
Set the brilliance for key LED.
Select the engine-related data to show from
[ENGINE], [SHAFT], or [PITCH].
Select the number of engine, shaft, or propel-
ler.
Set the wind averaging time to smooth wind
data. The longer the setting, the more the data
is smoothed. To find the momentary wind di-
rection and speed, select the shorter time.
Select the mounting location of the rudder
from [SINGLE], [STBD] (starboard), or
[PORT].
Select the indication of direction from [AR-
ROWS] or [TEXT] for speed, ROT (rate of
turn), rudder and engine/shaft/pitch.
If there is a difference between the dot-matrix
LED brilliance and the 7-segment LED bril-
liance, adjust the DOT LED CAL or 7-SEG
LED CAL so that both brilliances are the
same. -3 is the darkest and 3 is the brightest.
