For full functionality of the chartplotter you need to provide position and
heading data.
• Orientation - heading data is required for chart to operate in Course Up and
Head Up.
• MOB requires heading and speed data. Alternatively, SOG and COG
(derived from the same source as position data) enable the MOB function.
• Position data is required for full functionality of the chart display.
Full details of heading, position and other data are given in Section 6.8.
Planning the Installation
Before you install your system, plan the installation, considering:
• Location of the display unit, as described in Section 6.3 .
• Cable Runs, including cables for an integrated system (to provide heading
and position data etc.), as described in
Section 6.4 .
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
normally be assumed to spread 20 degrees above and below the radiat-
ing element.
