C15 Beep when key is pressed

Setting KEY On will make a beep at every key press, and when KEY is
OFF. There is no beep.
5.1.5

C16 Referens pointer On/OFF

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.

C17 "Knock Timer" KTR

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.

C22 Calibration of log transducer

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.
