Preface ix• Make sure that all members of crew know how to disengage theautopilot.• Regularly check for other boats and any obstacles to navigation –no matter how clear the sea may appear, a dangerous situation candevelop rapidly.• Maintain an accurate record of the boat’s position by using eithera navigation aid or visual bearings.• Maintain a continuous plot of your boat’s position on a currentchart. Ensure that the locked autopilot heading will steer the boatclear of all obstacles. Make proper allowance for tidal set – theautopilot cannot.• Even when your autopilot is locked onto the desired track using anavigation aid, always maintain a log and make regular positionalplots. Navigation signals can produce significant errors undersome circumstances and the autopilot will not be able to detectthese errors.EMC conformanceAll Raymarine equipment and accessories are designed to the bestindustry standards for use in the recreational marine environment.The design and manufacture of Raymarine equipment andaccessories conform to the appropriate ElectromagneticCompatibility (EMC) standards, but correct installation is required toensure that performance is not compromised.Handbook informationTo the best of our knowledge, the information in this handbook wascorrect when it went to press.
