General Mounting Instructions - Hatteland HD 12T04 series User Manual

General Installation Recommendations
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 mounted
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.
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.
