4.1 Mounting location
Choosing the right location is important for correct functioning of the display.
Please mind the following recommendations:

Although the display has an antiglare filter it is recommended to choose a position where the
displ
ay doesn’t reflect direct light.

If the operator will need to operate the display it must be in reach or the optional remote panel
should be installed.

Dimming can also be remotely controlled using the NMEA DCC message.

Allow enough space for cabling.

Allow enough space for service.

Mind the viewing distance according
IEC 62288:2014 paragraph 4.3:
o
For the wind speed indication in the center, the character height is 10 mm which
corresponds to a nominal viewing distance of 2.85 meters
o
For the other numeric fields the character height is 7 mm which corresponds to a
nominal viewing distance of 2 meters
4.2 Mounting position
The display can be mounted either in Landscape (default) or Portrait position.
Landscape is preferable since it allows maximum use of the display area. Portrait mode has 2 data
positions less.
The display can be panel mounted, desktop or ceiling mounted.
For ceiling or desktop mounting an optional bracket is available.

For new installations we recommend to use the large cut-out of 228x142mm.
Optional the display can be fitted in the 144x144 position (cut-out 138x138mm) and optional spacer is
available. This can be useful for refits (replacement of the OMC-138, 139 or 934 or any other 144
