Engaging the autopilot could not be easier. Simply steer your vessel onto the required heading, press the AUTO button and release the wheel/ tiller. When you want to return to manual steering simply press STANDBY and regain control. Caution: Hand steering is not possible when your vessel is under autopilot control. The pilot MUST be disengaged by pressing STANDBY. It is the skippers responsibility to ensure that all crew members are aware of this procedure. Course Changes Course changes under autopilot control are made using the ­1, +1, ­10 and +10 keys. These keys allow you to make changes in 1° or 10° increments to port (­) and starboard (+). Track Track mode tells the autopilot to steer under the supervision of a radio or satellite navigation system. Therefore, the following basic guidelines should be observed before track is engaged: · Always steer your vessel to within 0. 1nm of the track. · Make sure that there are no navigational hazards either side of the intended track. · Make regular plots to verify the computed position provided by your position transducer. · Maintain a proper lookout at all times. 6 ST80 Autopilot Keypad Operation Manual Track Advance/Acceptance If your navigation receiver is transmitting waypoint number and bearing to waypoint, a waypoint alarm will sound whenever a new target waypoint is selected. The autopilot maintains the current heading and automatic track control is suspended. Check the new bearing to waypoint, make sure that it is safe to turn, and then return to automatic track control by simply pressing the track key. The new target waypoint is accepted and the autopilot steers your vessel onto the new heading. You may find that the tidal offset is very different on the new bearing. Therefore, it is advisable to check the cross track error (XTE) after a couple of minutes. If the cross track error increases, make a course adjustment (e. g. , 10°) in the direction of the arrow. This helps to speed up track control correction for the new tidal vector. Response There are three response levels. Level 1 is the default and suitable for most situations. This setting provides the best compromise between course-keeping accuracy and power consumption. Level 2 ensures tighter course-keeping at the expense of increased power consumption and wear and tear due to increased pilot activity. [. . . ] Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but good installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product. 3. 2 Installation To avoid the risk of operating problems, all Autohelm equipment and cables connected to it should be: · At least 1m (3 feet) from any equipment transmitting or cables carrying radio signals, e. g. , VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 2m (7ft). · More than 2m (6ft) from the path of a radar beam. [. . . ]
