Rudder Bias will be the first line on the list, and will show the current helm bias. You can
change this value to suit, using the COURSE CHANGE knob. This feature is useful in
order to accommodate changing load or sea conditions.
As mentioned earlier, WORK mode will automatically be disengaged if the boat’s speed
rises above the Work Trip Point set by the user. While it is disengaged, all normal features
such as automatic trim and off-course alarm will be operational.
Manual WORK Mode
Even if no NMEA source of speed data is available, WORK mode can still be used, by
manually initiating it.
To do so, switch to AUTO or NAV mode, and then press the WORK button for ~1 second
until the letter `A´ or `N´ in the upper left portion of the display stops flashing, and a small
letter `W´ appears beside it.
Then, double-press the WORK button to bring up the Work menu. Highlight “Work Mode
State”. Then use the COURSE CHANGE knob to change the selection to “M_On” (Manual
On). WORK mode is now engaged.
Caution! When Manual WORK mode is engaged, large rudder movements may occur. If
your boat is traveling too fast, these rudder movements may affect the stability of the
boat. Do not engage Manual WORK mode without first ensuring that it is safe to do so
and that the boat speed is appropriate for using WORK mode.
To disengage WORK mode, again select “Work Mode State” in the Work menu and
change it to “A_Rdy” (Automatic Ready).
To cancel WORK mode completely, press and hold the WORK button for 1 second, or switch
to STANDBY or POWER STEER mode.
You can also manually disengage WORK mode, if it has been engaged in the automatic
mode. Double-press the WORK button to bring up the Work menu. If WORK mode is
engaged, the “Work Mode State” will show “A_On” beside it. Highlight “Work Mode State”,
then use the COURSE CHANGE knob to change it to “M_Rdy” (Manual Ready).
