2.8.5 Heat Management: The display is designed to work within most high ambient heat
conditions. There are extreme yet rare conditions that may cause the display to go
black or " Blackout ". This is normally caused by concentrated and excessive UV rays
(DIRECT SUNLIGHT) acting on the LCD panel.
To minimize the risk of the Display being subjected to the above one should endeavour
to:-
2.8.5.1
2.8.5.2
EMC Guidelines
2.9
All Nauticomp Displays and accessories are designed to the best industry standards for use in the
rugged electronic environment. The design and manufacture conforms to the appropriate
Electromagnetic Compatibility (EMC) standards (Section 1.4.5 refers), 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 where ever possible Nauticomp Displays and
cables connected should be:
2.9.1 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).
2.9.2 More than 7 ft (2 m) from the path of a radar beam. A radar beam can normally be
assumed to spread above and below the radiating element.
2.9.3 Supplied from a separate battery from that used for engine start. Voltage drops below
10 V, and starter motor transients, can cause the equipment to reset and or cause the
loss of some information and may change the operating mode.
2.9.4 Used with Nauticomp specified cables. Cutting and rejoining (Splice) these cables can
compromise EMC performance and must be avoided.
NOTE:
If a suppression ferrite is attached to a cable; this ferrite should not be removed.
Employ additional cooling to assist with heat dissipation.
Provide additional shading.
