light conditions and reflections. |
|
2 |
Make sure that the physical installation of the unit has been completed.
|
a |
Make sure that the structure to which the display is fastened is substantial enough to hold the unit securely under all operating
conditions. |
|
b |
Make sure that ample space is provided around the unit to allow for maintenance and replacement of parts. |
|
c |
Make sure that the bolts, screws or studs that have been used are all of the correct size. |

|
e |
Make sure that all the nuts have been tightened properly. |
|
f |
If applicable: Make sure that ample ventilation is provided to avoid overheating. |
|
g |
If applicable: Make sure that the display (or the display mounting bracket) is bolted or welded securely to the deck and/or bulkhead. |
|
h |
If applicable: Make sure that all welds and brackets have been painted with the correct preservation medium to prevent corrosion. |
|

3 |
Make sure that the unit is not physically damaged, and that the surfaces and paint-work are clean without dents or scratches.
The physical handling during the installation may have caused some minor scratches to the surfaces or paint-work. This can be accepted. However, if rough handling has caused serious damage, this must be recorded with a written statement and necessary photos,
so that corrective actions can be made.
