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.
