The text [CHK] starts flashing and a pointer will show you the

course where to end. When you have taken the boat through the

minimum 360°

turn, press SET again, and if successful, the text [CHK Atd] will

appear again, otherwise, ERR 17 or ERR 19 will appear, i.e. the

difference between the last Autodeviation and this Autocheck is to

big to be accepted. Make a new Autocheck, and if you still get ERR

19, make a new Autodeviation since the last one was probably

disturbed.

When the Autocheck is OK, the Compass will store the average

result from both Autodev and Autocheck.

If you by any reason prefer to reset the deviation created by the

Autodeviation function, press SET when text [CLR Atd] is

displayed, you are now asked to confirm the flashing text YES by

another press on KEY, or select no by use of PLUS or MINUS

button, then SET.

This function is used when the Compass is giving a constant

course error, i.e. it is not mounted exactly aligned as the boat (there

is no need to mount the transducer at the boats centreline). Make

sure that the local magnetic variation is entered before you make

the alignment adjustment, otherwise you are unable to see the

difference between local magnetic variation and alignment error.

The Compass may be installed reversed 180° , but never at

perpendicular, or 90° relative the centreline.

when the boats average course is more thenset value. The text

[OCA OFF

allowed course error, then press SET again.
