2.3.1.6 Joystick Gain Setting
The system starts up in Joystick Manual. This mode can take full use of all thrusters. To limit the system to use less than
maximum thrust, the JSM GAIN setting is available. The joystick gain setting is used for both joystick modes; manual
joystick as well as auto joystick mode. See Heading and Position Keeping Gain, Speed and Alarm Settings on page
36.
The Joystick Gain (%) (parameter adjustable) value determines the amount of thrust supplied when the joystick or
rotation button is moved to most outer positions. (If set at 100% is full thrust). Advisable value in harbor is approximately
30%.
