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
•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. VHF radios, cables and antennas. 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 nor- mally 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 dam-
