Safety instruction: Indicates a hazardous situation that, if not avoided,
could result in death or serious injury.
CAUTION!
Safety instruction: Indicates a hazardous situation that, if not avoided,
could result in minor or moderate injury.
NOTICE!
Indicates a situation that, if not avoided, can result in property damage.

Supplementary information for operating the product.
2 General safety instructions
The manufacturer accepts no liability for damage in the following cases:
• Physical damage to the product.
• Damage due to incorrect installation or connection voltage.
• Alterations to the product.
• Use for purposes other than those described in the operating manual.
The CE declaration of conformity can be requested from the manufacturer (contact
information on the back of this manual).
2.1 General safety
• Read and understand all instructions included with your system prior to use.
• Disconnect power from the actuators (with battery switches or circuit breaker)
before working at the transom of the boat.
• Only use the trim tab system as intended.
• Do not use tabs as a boarding step.
•
When liing the boat, do not place the liing straps or forks on the tabs or actuators.
• Do not push or pull on the tabs or actuators when putting the boat on or off
a trailer.
• Do not tie off or secure anything to the actuators.
• See an Optimus-certified dealer for repairs if the trim tabs, actuators, or controller
are modified, damaged or not working correctly.
•
The controller and actuators are not user serviceable; do not attempt to disassemble.

2.2 Safe operation
• The trim tab actuators are powerful mechanical devices that can cause injury.
Ensure no one is at risk of being injured before operating a tab when
swimmers are in the water, or when operating the tabs on a trailer with people
or children around.
• The trim tab system is not a toy. Do not allow children to operate the system.
WARNING!
Exercise sound judgment when using trim tabs in challenging sea
conditions. In some cases the safest action is to run with tabs fully
retracted.
3 Technical description
Your Adaptive Trim Tab System is the industry’s first trim system with position feedback.
This state-of-the-art system gives you immediate, precise, and repeatable control of
vessel trim. With built-in intelligence, it can be integrated with Optimus Electronic
Power Steering for complete vessel control. When integrated with Optimus, the
system is called the Optimus Adaptive Trim Tab System.
The AdaptiveTrim Tab System consists of three primary components: the adaptive
actuators, the sheet metal tabs, and the adaptive dial controller. The adaptive dial
controller is unique in the industry with smart function buttons and an intuitive dial
control that makes roll adjustment simple and obvious.
The system operates on 12VDC, and uses a Controller Area Network (CAN) bus for
communications. The controller can control up to four trim tab actuators and precisely
synchronize their movement.

4 Trim tab principles of operation
Trim tabs are plates, installed in pairs, used to control the pitch and roll of a boat
by directing water as it flows past the transom. They work by harnessing the
hydrodynamic forces exerted by moving water, so the boat must be in motion
for the tabs to have an effect.

3.2 Controller operating and display elements
WITH TRIM TABS IN USE WITHOUT TRIM TABS
When a tab is lowered, the directed water flow will exert an upward force at the stern
of the boat. If both tabs are lowered at the same time the upward force at the stern
will force the bow down (pitch control). If only one tab is lowered it will force the bow
down on the opposite side, causing the boat to roll (roll control). The combination
of pitch and roll is the boat’s attitude.
By adjusting the boat’s attitude, the boat operator can get on plane faster, stay on
plane at lower speeds, increase top speed, correct a small list, improve ride quality
and visibility, reduce porpoising, and improve fuel economy.

5.1 Basic features and operation
The dash-mounted Adaptive Dial Controller is designed for intuitive operation. The
function of each interface feature is described below.
Displays the status of the trim tab system.
Steady green System is ready
Steady magenta Holeshot mode is activated, based on SOG
Steady lime green Holeshot mode is activated, based on RPM
Flashing blue System is in LED brightness adjustment mode
Flashing cyan The system has memorized the favorite position
Steady blue Tabs retracted automatically
Flashing yellow Controller has a non-critical fault (see section 6)
Flashing red Controller has a critical fault (see section 6)
System
Status
Indicator
Shows the position of port and starboard tabs. At full retraction a
single LED is shown at the top. As the tabs are extended the LEDs will
illuminate to show the tab position.

Lowers both tabs simultaneously, causing the bow to drop. Press and
release to move both tabs a preset increment, or press and hold until
the desired pitch is achieved. To enable fine control, the actuator
speed is reduced for the first second the button is held, aer which
the actuators move at full speed for larger adjustments.
Raises both tabs simultaneously, causing the bow to rise. Press and
release to move both tabs a preset increment, or press and hold until
the desired pitch is achieved. To enable fine control, the actuator
speed is reduced for the first second the button is held, aer which
the actuators move at full speed for larger adjustments.
Rolls the boat in the direction of rotation. Rotating the dial to starboard
(clockwise) will cause the port tab to lower and the starboard tab to
raise, causing the boat to roll to starboard. Turning the dial to port
(counterclockwise) will have the opposite effect.

Use this control with caution: turn one click at a time and wait a
moment to see how the boat reacts before making further adjustments.
While this control can be used to correct a list due to uneven loading,
best practice is to load your boat as evenly as possible, and to keep
passenger movement at a minimum while underway at high speeds.
The relative positions of the tabs are maintained when using the Bow
Down and Bow Up controls, so if you’ve used the roll control to
correct for a list it will remain corrected as you alter the bow position.
Press once to retract actuators to their fully retracted home position.
Use this button when:
• you encounter difficult sea conditions and need to raise the bow,
• preparing to load the boat onto a trailer,
• preparing the boat for liing.
The home button will immediately override any automatic operation
of the trim tab actuators and return them to home position. When the
tabs reach the home position the trim tab position indicator LED will
blink three times.
The Favorite button has two functions, described in detail in section 5.2:
1. Set and recall a Favorite trim tab position.
2. Toggle Holeshot mode on or off.
You can switch between these functions by pressing and holding the
Favorite and Bow Up buttons together for three seconds. The system
status indicator will briefly flash magenta to show the Holeshot function
is enabled, or green to show the Favorite function is enabled.
5.1.1 Adjusting LED brightness
Press and hold the Home and Favorite buttons together.
✓The system status indicator flashes blue and the starboard tab position
indicators all light up.
✓As you continue to hold the buttons, the brightness of the LEDs will cycle
through five levels.
Release the buttons at the desired brightness level.

NOTE: Integrated brightness control
If your boat is equipped with Optimus Electronic Power Steering (EPS),
the trim tab controller brightness can be adjusted using the CANtrak
display’s brightness control. See your Optimus User Manual for
instructions.
NOTE
To use this function it must be enabled. See the description of the
Favorite button in section 5.1.
5.1.2 Preparing to trailer or li the boat
Press the Home button.
✓The actuators will retract. When both tab position indicators show only one
LED, the tabs are fully retracted.
You are ready to trailer or li the boat.
NOTICE! Material damage
Trailering or lifting the boat with the trim tabs extended may cause
irreparable damage to the tabs and actuators.
5.2 Advanced features and operation
5.2.1 Setting and recalling a favorite position
With this function you can memorize a trim tab position and return to it at any time
with a single press of a button.
Setting a favorite position:
Press the Favorite button (fig. 21, page 1) for five seconds.
✓The system status indicator will flash cyan three times to confirm the position
has been saved.
Recalling a favorite position:
Press the Favorite button.
✓The tabs will adjust to the saved favorite position.
CAUTION! Varying sea conditions
If sea conditions have changed since you last set a favorite position,
use caution when recalling it.
