2) The lower button retracts the blades in parallel
("BOW UP").
3) The left button lowers the starboard blade and
retracts the port blade ("TILT PORT").
4) The right button lowers the port blade and retracts
the starboard blade ("TILT STARBOARD").

NOTICE
The trim tab blade operation starts when
pressing the button and stops when releasing
it.
NOTICE
When the engine stops (power supply to the
panel is lost), the trim tab blades will fully
retract after a few seconds.
The LEDs on the panel have variable light intensity
in four steps and OFF. By pressing the left and right
buttons simultaneously for approximately 1 second,
the light intensity of the LEDs takes one step
down. As long as the 2 buttons are pressed in, the
intensity takes one more step down for each 0.5
second. When the intensity reaches the OFF level,
it returns to maximum intensity again and keeps
toggling like this as long as the 2 buttons are pressed
in. When the buttons are released, the intensity of the
LEDs will stay at the current value. If several panels
are connected to the system, only the panel where the
buttons are pressed will be affected. After power off,
the panel LEDs will restart at maximum light intensity
when power on.

B. Control Listing
Wind, loading and many other factors can result in the
boat tilting or leaning towards one side while running.
This is called listing and can be negated using trim
tabs.
After stabilization of speed and direction, press the
correct trim tab button to achieve a level side to side
running attitude.
C. Induce Planing & Controlling Trim Angle
Trim tabs can also be used to facilitate faster planing
and allow better control of the running angle.
Before accelerating and trying to gain plane, press
upper button. This will cause both trim tab blades to
lower in parallel and force the bow down when
running. This can also be used when running the boat
with a heavy load aboard.
Moving the trim tab blades downward will in crease the
lift and the boat will achieve plane faster, or stay on
plane at a lower engine and boat speed.
After gaining plane and establishing cruising speed,
pressing the lower button retracts the blades in
parallel and will allow the bow to rise. This should be
used to adjust the run ning attitude of the boat to
decrease the drag at cruising speed or above, or
when run ning in a following sea.
When running at an engine speed that results in the
boat falling off plane or causes the boat to plane
inefficiently, lowering the blades slightly (bow down)
will improve the running angle and improve operating
efficiency.
Optimum efficien cy is obtained when operat ing at a
3 to 5 degree running angle. Utilizing too much "Bow
Down" trim tab can reduce operat ing effi ciency and
cause substan tial stee ring and handling difficul ties.
Be extreme ly careful when running in a following sea.
The effect of trim tabs is ampli fied under such condi-
tions. Steer ing and handling difficulties can result from
im proper trim tab usage, espe cially in a following sea.
If unsure of proper trim tab positioning, raise the trim
tabs to the full-up position.
