BASIC OPERATION
AUTOPILOT
Turn the master select switch to the STANDBY
position. The display will show the vessel's
current compass heading. If the heading displayed
by the autopilot does not agree with the compass,
press and hold the GYRO OFF or WIND OFF
key, and then use the up or down ARROW key
to adjust the heading on the display.
Turn the master select switch to the POWER
STEER position. The red and green ARROW
keys can now be used to turn the rudder port and
starboard. The display will continue to show the
vessel's current compass heading.
Turn the master select switch to the PILOT
position. The vessel will continue on its present
heading under autopilot control. Adjust the
RUDDER, COUNTER RUDDER, and YAW
controls for the best steering. Touch the
COMPASS key to view the vessel's actual
compass course on the display. Touch the
COURSE key to return the programmed course
to the display.
Leave the master select switch in the PILOT
position. Estimate the number of degrees of
course change required. Alter course in one
degree steps by pressing and releasing either the
red or green ARROW key. Alter course by ten
degrees per second by pressing and holding either
the red or green ARROW key until the display
shows the desired course. Press the U-TURN key
together with either the red or green ARROW
key for 1 second to start a special turn (U-Turn,
Emergency Turn, or Continuous Turn) in that
direction.
Press either the red or green DODGE key for a
panic turn in that direction to avoid obstacles in
the water. When the vessel has turned far enough
to clear the obstacle, press and hold both
DODGE keys to hold the vessel off course. The
vessel will return to the programmed course at the
rate set by the TURN RATE control when the
DODGE keys are released.
Turn the master select switch to the NAV
position when the autopilot is to interface with a
Navigation Computer. The autopilot will set its
own course using information sent to it by the
Navigation Computer. To select which Nav Port
is active, press the U-TURN key followed by the
red ARROW key. To select the Cross Track
Error sense (normal or inverted) for the selected
Nav Port, press the U-TURN key followed by the
green ARROW key . The DODGE keys operate
as described in (5) above, except that the vessel
will return to the original track to the waypoint,
rather than the original course, when the DODGE
keys are released.
For more complete operating instructions,
refer to the CONTROLS and OPERATION
sections.
