Multi-media chart cards
The A-Series Multifunction Display is pre-loaded with Navionics
chart data. If you wish to use different chart data, you can insert
Navionics chart cards into the CompactFlash card slot on the unit.
When archiving data, Raymarine recommends the use of SanDisk
CF memory cards. Other brands of CF memory card may not work
in your unit.
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 Electro-
magnetic 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 equipment.
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.
• Place equipment at least 5ft (1.5 m) from any equipment trans-
mitting or cables carrying radio signals, e.g. VHF radios, cables
and antennas. In the case of SSB radios, the distance should be
increased to 7ft (2 m).
• Place equipment more than 7ft (2 m) from the path of a radar
beam. A radar beam can normally be assumed to spread 20 de-
grees 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 and starter mo-
tor transients can cause the equipment to reset. This will not
damage the equipment, but may cause the loss of some infor-
mation and may change the operating mode.
• Cables are not cut or extended unless doing so is detailed in the
installation manual.
Remember
Where constraints on the installation prevent any of the above
recommendations:
• Always allow the maximum separation possible between differ-
ent items of electrical equipment. This will provide the best
conditions for EMC performance for the installation.
