ComNav Marine 1420 Autopilot System
Setting the Fast Speed Rudder
Response
In order that the 1420 Autopilot can steer
your boat in a straight line & make
smooth turns when your boat is moving at
“fast” speeds, you will need to adjust the
Sensitivity of the Fast Speed Rudder
Response.
These adjustments are very similar to the
ones you made for Slow Speed Rudder
Response.
Press the Pilot Key
to start steering a
Course with the Autopilot.
Advance the throttle so that your vessel is
moving at a “fast” speed (for example,
your normal Cruising speed).
To select the Fast Speed Rudder
Response, press the Speed Key twice
quickly. The light below the Speed Key
will turn on to tell you that the fast speed
Rudder Response is now active.
⇒ If your vessel is turning back and forth
across the course line, the Fast Speed
Sensitivity is set too high.
To decrease the Sensitivity
Press and hold the Speed Key
. Press the
Red Key
briefly. Wait a few minutes, and
see if the boat settles on a steady
Course.
Continue this procedure until the boat is
steering satisfactorily.
⇒ If your vessel falls away from the
Course line, the Fast Speed Rudder
Response Sensitivity is set too low.
To increase Sensitivity:
Press and hold the Speed Key. Press the
Green Key.
If the vessel continues to fall away from
its course, repeat the above steps.
Fast Speed Turns and Course
Changes
All the Autopilot’s Turn, Course Change
and Dodge features described above for
the Slow Speed Rudder Response also
work when Fast Speed Response is
selected.
But!
Your vessel will turn more quickly than it
does when you are using the Slow Speed
Rudder Response.
Experiment with Turns, etc. at Fast
Speed Response, so that you will be
familiar with the effects.
All commands in the Fast Speed Rudder
Response setting work as they did in the
Slow Speed Response setting.
A table of all Autopilot commands is
provided at the end of this manual (see
page 53).
