Introduction WARNING See the Important Safety and Product Information guide in the product box for product warnings and other important information. You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that will enhance your capability to operate your boat. It does not relieve you from the responsibility of 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. In addition to the basic heading-hold functionality, the system allows manual steering and several modes of automatic-steering functions and patterns. You can operate the autopilot system using the helm control device. Using the helm control, you engage and steer, set up, and customize the autopilot system. For information about installing, see the installation instructions for each device. Device Overview À Á Â Ã Autopilot status/autopilot status indicator.
