rudder gain (RUDD GAIN) screen
• then press -1 or +1 to change the level
•press disp or wait for 5 seconds to return to the previous
display and save the temporary changes

course keeping. By minimizing helm movements this will reduce
power consumption and wear.

permanent rudder gain setting in Dealer setup (see page 94).
