Advanced use of (STR) MEM
The text [STR OFF] or [MEM] is displayed.
Press CLEAR. The text [OFF] or [MEM] is flashing, select one of
the following four different steering modes that are available;
[MEM], [AWA], [BTW], [CTS] or [OFF] and press SET.
Each function is explained in detail. The function [STR] is a Nexus network function,
i.e. it will transmit the steer reference data to other FI-30 instruments. The steer
information used on the Compass Data instrument is functioning within the same
concept as the  STEER Pilot  instrument. The instrument is  especially designed for
displaying steer or Compass heading information in the most efficient way. You may
also use one or more external TRIM buttons to set new references. To be able to
utilise the wind steer function AWA, you will need either a Wind Data instrument, or a
FI-30 Server with a wind transducer. For the [BTW] and [CTS] functions you will need
any NMEA GPS, Decca or Loran C navigator to be connected.
Also, if you have installed a FI-30 Autopilot, and it is activated, you may change the
course or wind angle by using the STR function.
You can not activate or turn the pilot off with STR, so use with care !

Press CLEAR. The text [OFF], [MEM] or the previous selected function is flashing,
select [AWA] and press SET.
A copy of the present  windangle is flashing, press SET  to accept, or enter preferred
windangle, then confirm with SET.
You will now see the text WA flashing with a pointer at the left or right side. For now,
just press the SET  again, then press  PAGE to see the closed
hauled angle.
Example, you have set 40
°
 as your tacking angle.

windangle deviation is displayed as a filled sector. When
sailing too high, segments are.
