1 Introduction
The OMC- 140 is a multi functional NMEA display primarily designed for wind information.
It is capable of calculation Theoretical and True wind if required data is available.
This manual is intended for the Operator of the display.
An Operators Guide with the basic essential information is also available.
For installation instructions we kindly refer to the Installation manual.
The Installation manual also contains information for the system administrator.

2 Safety
Do not open display.
Potential lethal voltages inside.
No user exchangeable parts inside.
Only use indoors.
For outdoor use an IP66 or better housing is required.
For correct functioning of this display the display and connected
sensors must be installed according installation instructions as
described in the OMC-140 Installation manual.
Remember: instruments are tools.
They do NOT replace your own observations!
After end of life dispose this product according local regulations or
return to manufacturer.
