The LED on the Take Command button is used to indicate joystick status:
LED State Joystick Status
Off joystick is inactive
Steady blue joystick has control of the vessel
Slow flashing blue joystick is initializing rudder and EST system
Alternating red and joystick has control of the vessel, but there is an
blue flashing active non-critical warning fault*
Fast flashing red joystick has a critical fault* and is awaiting transfer
of control to a control head
Steady red joystick has a critical fault* and is not available for
operation
* See section 4 for fault handling information.

Used with the optional SeaStation boat positioning system (see separate
instructions if so equipped).
Operation fundamentals
The levers on the active control head must be in the neutral position before
a joystick may take command of the system.
1. The joystick has three primary operational modes (see figures next page):
a) Forward/Reverse – engaged by pushing the joystick directly fore/aft.
Causes the boat to move directly fore and aft. In this mode, the boat
can be steered by rotating the handle. Always engage the Forward
Reverse Mode by moving the handle directly fore/aft then rotating the
handle to steer. Rotating the handle first then pushing fore/aft would
enter Rotation Mode and apply a forward correction in rotation mode.
b) Sideways – engaged by pushing the joystick directly to port or
starboard.
Causes the boat to move directly sideways. In this mode, the handle
can then be moved fore/aft or rotated to correct the vessel's
heading or position.
c) Rotation – engaged by twisting the joystick while it is at center
position.
Causes the boat to rotate on the spot. A fore/aft handle movement
after engaging rotation mode will cause the boat to rotate but with a
forward or reverse bias. Always engage Rotation Mode first then
apply the desired correction. Pushing the handle fore/aft then
twisting would cause the system to enter Forward/Reverse mode
with a steering correction.
2. When released, the joystick always returns to the center position,
which provides neutral-idle for engines.
3. The joystick is proportional and guided in each axis — the more the
joystick is moved, the more throttle is applied.
See the following pages for examples of each of the primary
operational modes.
