General Installation Recommendations

Ergonomics

1. The front surface of the display glass has an anti-reflective (AR) coating which can be scratched and damaged with
improper cleaning. It is recommended to use only 90+% pure Isopropyl alcohol (Isopropanol) and a soft fabric cloth
for this first cleaning. Fold a cloth into a small pad, dampen the cloth with alcohol, and wipe the glass from one edge
to the other in one direction with one continuous motion.
The product glass will require cleaning as needed. The soft cloth & alcohol wipe is recommended to clean
fingerprints and oils off the glass. Water stains (including coffee, tea & coke) should be first cleaned off the glass
with a soft fabric cloth wet with water, immediately followed with wiping using an alcohol wetted cloth.
2. 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.
3. Adjust screen inclination to remain gaze angle to the centre of the screen approximately perpendicular to the line
of gaze.
4. 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 favourable.
5. Series 2 are optically enhanced to reduce reflections and are viewable in direct sun light, but as a general rule the
units at the bridge wing area is recommended to be installed or mountedby suitable alignment or bulkhead / deck-
head 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.
6. 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).
General mounting instructions
- The useful life of the components of all Electronics Units generally decreases with increasing ambient temperature;
it is therefore advisable to install such units in air-conditioned rooms. If there are no such facilities these rooms must
at least be dry, adequately ventilated and kept at a suitable temperature.
- With most Electronic Units, cooling takes place via the surface of the casing.
- In the area of the wheel house, the distance of each electronics unit from the magnetic standard compass or the
magnetic steering compass must not be less than the permitted magnetic protection distance.
This distance is measured from the centre of the magnetic system of the compass to the nearest point on the
corresponding unit concerned.
- Units which are to be used on the bridge wing must be installed inside the "wing control console" protected against
the weather. In order to avoid misting of the viewing screen, a 25 ... 50 W console-heating (power depending on the
volume) is recommended.
- When selecting the site of a display unit, the maximum cable lengths have to be considered.
- 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.
