Speed Log
Same procedure as in STANDBY mode.
Off Heading Lim
Same procedure as in AUTO mode.
Nav Gain
The Navigation Gain determines how many degrees the
autopilot must change the vessel's heading in order to bring the
vessel back on track using the Cross Track Error and the
vessel's speed.
The higher the value of the Nav Gain, the greater the correction.
If the value is set too low, the vessel may use a long time to
reach the track. It can also drift away at strong side current.
Too high value will cause the vessel to overshoot or oscillate
around the track.
The default setting depends on the boat length and the range is
0.5 to 7.0.
Turn Mode
Same procedure as in AUTO mode.
ROT/RAD
Same procedure as in AUTO mode.
Thruster Sens
Same procedure as in AUTO mode.

NAV-WORK Mode

To enter the User Set-up menu when in NAV-WORK mode,
quickly double press the NAV-button.
The User Set-up menu for the NAV-WORK mode is identical to
the NAV mode User Set-up menu, except that you have the
option to select separate NAV-WORK values for Seastate filter,
Rudder, Counter Rudder and RateOfTurn. Move through the
menu item by pressing the Port and Stbd buttons. Use the course
knob to change value.
Selected values for Seastate filter, Rudder, and Counter
Rudder are stored in the AP50 memory and are automatically
recalled when returning to NAV-WORK mode.
