Measuring the Potential Front-of-Boat Offset
The front-of-boat offset compensates for the physical location of
the radar scanner on a boat, if the radar scanner does not align
with the bow-stern axis.
1
Using a magnetic compass, take an optical bearing of a
stationary target located within viewable range.
2
Measure the target bearing on the radar.
3
If the bearing deviation is more than +/- 1°, set the front-of-
boat offset.
Setting the Front-of-Boat Offset
Before you can set the front-of-boat offset, you must measure
the potential front-of-boat offset.
The front-of-boat offset setting configured for use in one radar
mode is applied to every other radar mode and to the Radar
overlay.
1
From a Radar screen or the Radar overlay, select Menu >
Radar Setup > Front of Boat.

Autopilot
You can use the autopilot feature only at a station installed next
to a helm, throttle, and helm control device.
You are responsible for the safe and prudent operation of your
vessel. The autopilot is a tool that enhances your capability to
operate your boat. It does not relieve you of the responsibility of
Autopilot
WARNING
safely operating your boat. Avoid navigational hazards and
never leave the helm unattended.
Always be prepared to promptly regain manual control of your
boat.
Learn to operate the autopilot on calm and hazard-free open
water.
Use caution when operating the autopilot near hazards in the
water, such as docks, pilings, and other boats.
The autopilot system continuously adjusts the steering of your
boat to maintain a constant heading (heading hold). The system
also allows manual steering and several modes of automatic-
steering functions and patterns.
Opening the Autopilot Screen
Before you can open the autopilot screen, you must have a
compatible autopilot installed and configured.
Select A/V, Gauges, Controls > Autopilot.

rudder sensor is connected.)
Adjusting the Step Steering Increment
1
From the Autopilot screen, select Menu > Autopilot Setup >
Steering Mode > Step Turn Size.
2
Select an increment.
Setting the Power Saver
You can adjust the level of rudder activity.
1
From the autopilot screen, select Menu > Autopilot Setup >
Power Saver.
2
Select a percentage.
Selecting a higher percentage reduces rudder activity at the
expense of heading performance. The higher the percentage,
the more the course deviates before the autopilot corrects it.
TIP: In choppy conditions at low speeds, increasing the
Power Saver percentage reduces rudder activity.
Enabling Shadow Drive
NOTE: The Shadow Drive feature is available only on hydraulic
steering systems.
From the autopilot screen, select Menu > Autopilot Setup >
Shadow Drive > Enabled.
Engaging the Autopilot
When you engage the autopilot, the autopilot takes control of the
helm and steers the boat to maintain your heading.
From any screen, select Engage.
