4) When selecting the site of a display unit, the maximum cable lengths have
to be considered.
5) When a product is being installed, the surface base or bulkhead must be
checked to ensure that it is flat in order to avoid twisting of the unit when
the fixing screws are tightened, because such twisting would impair
mechanical functions. Any unevenness should be compensated for by
means of spacing-washers.
6) The grounding screws of the units must be connected to the body of the
ship (ground); the wire used should have a cross sectional area of at least
6 mm
2
(10AWG).
7) Transportation damage, even if apparently insignificant at first glance,
must immediately be examined and be reported to the freight carrier. The
moment of setting-to-work of the equipment is too late, not only for
reporting the damage but also for the supply of replacements.
8) The classification is only valid for approved mounting brackets provided by
C & C Technologies. The unit shall be mounted stand-alone without any
devices or loose parts placed at or nearby the unit. Any other type of
mounting might require test and re-classification.
Ergonomics
1) Adjust the unit height so that the top of the screen is at or below eye level.
Your eyes should look slightly downwards when viewing the middle of the
screen.
2) Adjust screen inclination to remain gaze angle to the center of the screen
approximately perpendicular to the line of gaze.
3) When products are to be operated both from a sitting position and from a
standing position, a screen inclination of about 30° to 40° (from a vertical
plane) has turned out to be favorable.
4) The brightness of displays is limited. Sunlight passing directly through the
bridge windows - or its reflection - which falls upon the screen workplaces
must be reduced by suitable means (negatively inclined window surfaces,
venetian blinds, distance from the windows, dark coloring of the
deckhead). However, units can be offered with optical enhanced
technology to reduce reflections and are viewable in direct sun light; but
as a general rule it is recommended to install or mount the units at the
bridge wing area by suitable alignment or bulkhead / deckhead mounting
in such a way that reflections of light from the front pane of the display are
not directed into the observer’s viewing direction.
5) The use of ordinary commercial filter plates or filter films is not permitted
for items of equipment that require approval (by optical effects, “aids” of
that kind can suppress small radar targets, for example).
