7. If the push buttons of the product are not illuminated, an external, dimmable illumination (IEC 60945 Ed. 4, 4.2.2.3,
e.g. Goose neck light) is required for navigational use. The illumination shall be dazzle-free and adjustable to
extinction.
8. Information about necessary pull-relievers for cables is indicated in the Physical Connection section of this manual.
Attention must be paid to this information so that cable breaks will not occur, e.g. during service work.
9. Do not paint the product. The surface treatment influences on the excess heat transfer. Painting, labels or other
surface treatments that differ from the factory default, might cause overheating.
10. Expose to heavy vibration and acoustic noise might under certain circumstances affect functionality and expected
lifetime. This must be considered during system assembly and installation. Mounting position must carefully be
selected to avoid any exposure of amplified vibration.
Installation limitations
Due to environmental factors, please review the points noted below.
A: Overheat prevention:
For Maritime Multi Computer (MMC, Panel Computers) it is advised that you do not mount the unit in a
vertical angle lower than ±30 degrees, as noted in point 3 (previous section), i.e. flat mounting of the unit.
This is to prevent both overheating the unit as well as ensure proper cooling airflow to sustain long-life and
stable operation. Panel Computer units generate more heat than regular Display units naturally because of
CPU and mainboard chips.
It should be noted that 24” and 26” MMC units have internal fans providing additional cooling airflow of
their own, whilst smaller units (typically 8” to 19”) has no internal fans. In such cases, the ±30 vertical angle
may in certain situations allow for lower angle mounting provided that the console casing has adequate
cooling (see point D), however this is suggested as a trouble-shooting tip during installation or during short-
term observer use if found suitable. It should not be considered as a defintive trusted solution.
B: Glass Display Control™ (GDC) front glass touch buttons:
As this uses Projected Capacitive technology (instead of conventional hard physical buttons and knobs),
the touch controller can react and are sensitive to raindrops (for outdoor installations). To ensure that
raindrops do not stay on the unit’s flat glass surface, please do not mount the unit in a vertical angle lower
than ±30 degrees, i.e. flat mounting of the unit. This is to prevent accidental touches that are similar to a
human finger (cover area for a x period of seconds) as well as make sure the raindrops are “moving” and
slides down off the glass surface.
For Maritime Multi Display / Industrial Standard Display (MMD/STD) units (not Panel Computer units) the
angle could potentionally be lower as the On Screen Display (OSD) menu offers a “OSD Key Outdoor”
function with 5 seconds delay before activation on front glass functions. Please review the “OSD Menu
Functions” to learn more. In certain situations this might help, but is only suggested as a trouble-shooting tip
during installation or during short-term observer use if found suitable. It should not be considered as a
defintive trusted solution.
C: Projected Capacitive Technology (PCTouch) MULTITOUCH and in general Touch Screen glass:
For all units with a factory mounted touch screen and for outdoor use especially, please review point B above
regarding staying raindrops. Only solution to this situation is not to mount the unit in a vertical angle lower
than ±30 degrees, i.e. flat mounting of the unit to ensure touch screen is not activated and accidentally
automatically chooses functions in your running chart, radar or other software installed.
