Failure to do so could result in personal injury, damage to your boat and/or poor product performance. WARNING: Electrical safety Make sure you have switched off the power supply before you start installing this product. WARNING: Although we have designed this product to be accurate and reliable, many factors can affect its performance. [. . . ] For accurate speed readings the transducer should be sited within the clear water flow areas indicated by the shaded areas in the following diagram. Sailing vessel Planing power vessel Displacement power vessel Transducer siting D4349-1 The transducer should also: · Be ahead of the propellers (by a minimum of 10% of the water line length). · Be at least 6 in (150 mm) away from the keel (ideally ahead of the keel if a sailing yacht). · Be as near as possible to the center line of the vessel. · Be clear of other through-hull fittings or projections. Chapter 3: Installation · Have sufficient clearance inside the hull to fit the nut. · Have 4 in (100 mm) of headroom to allow for withdrawal. There must also be a viable route for the transducer cable to be routed to the instrument. 13 Instrument With standard bezel 4. 33 in (110 mm) 0. 95 in (24 mm) 0. 6 in (15 mm) With low profile bezel 4. 85 in (123 mm) ST60 instrument dimensions 0. 25 in 1. 4 in (6. 2 mm) (35 mm) D5785-4 CAUTION: The presence of moisture at the rear of the instrument could cause damage either by entering the instrument through the breathing hole or by coming into contact with the electrical connectors. ST60 instruments can be fitted either above or below deck, provided the rear of the instrument is sited where it is protected from contact with water. Each instrument must also be positioned where: · It is easily read by the helmsman. · It is protected against physical damage. · It is at least 9 in (230 mm) from a compass. 4. 85 in (123 mm) 3. 54 in (90 mm) diameter 4. 53 in (115 mm) 3. 54 in (90 mm) diameter 14 ST60 Speed Instrument Owner's Handbook · It is at least 20 in (500 mm) from radio receiving equipment. · There is reasonable rear access for installation and servicing. EMC installation guidelines All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment. Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct 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. The guidelines given here describe the conditions for optimum EMC performance, but it is recognized that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment. For optimum EMC performance, it is recommended that wherever possible: · Raymarine equipment and cables connected to it are: · At least 3 ft (1 m) from any equipment transmitting or cables carrying radio signals e. g. In the case of SSB radios, the distance should be increased to 7 ft (2 m). · More than 7 ft (2 m) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element. · The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. [. . . ] At the end of the return leg, press the trip key. At this point: · The text START 2 alternating with the new calibration factor is displayed at the top of the screen. · The displayed distance freezes. This value should be very close to the actual (measured) distance of the calibration run. 34 ST60 Speed Instrument Owner's Handbook 8. [. . . ]
