Setting  KEY On will make a beep at every  KEY-press, and
when KEY is OFF, There is no beep.

Setting  REF  On will show a reference pointer in the true
direction as a steer indicator in the Compass graphical mode.
When set to OFF, no reference indicator will be visible. When
the indicator is activated and a MEM course is set, this pointer
will slowly ”blink” and when overlapping your Compass pointer,
you are on course.

This is a race sailing function that will help you to decide when
to tack. When activated, a ”knock timer” will pop up when you
are sailing lower than the ”knock angle”. When the ”knock
angle” is set to 00 it is OFF.
Example, when KTR is set to 15

°

 and you are ”knocked” i.e. sailing 15

°

 lower than the

”reference set” course for more than 5 seconds, a timer will pop up, telling you the
elapsed time spent at ”knocked” angle. Also read chapter 4.5.3 Tactical use of MEM.

Calibration value for speed and distance (1.00 - 1.99).
Drive the boat a measured distance at normal speed.
Compare the distance with the trip counter.
Calculate the value with the following formula.

True distance from the sea chart: T
Log trip counter distance:

The current calibration value:

New calibration value:

If you suspect a current in the water, drive the boat in both directions and divide trip
counter distance by two.
