When a Jog Lever is activated, the rudder will move immediately in the requested direction,
to Port or Starboard (the autopilot system allows connecting any desired number of Jog
Levers).
As long as the Jog Lever is held activated, the rudder will keep moving in the corresponding
direction.
• If one or both of the Power Steer Rudder Limits and/or the Auto/NAV Limits are set, then
the autopilot will stop moving the rudder when it gets to the smaller of the limits.
• If neither of the Rudder Limits are set, then the autopilot will stop moving the rudder when
it gets within a few degrees of the physical limits of rudder travel.
When you release the Jog Lever, the autopilot will return the vessel to the current
commanded Heading if in AUTO or WORK modes, or to the current track to the next
waypoint if in NAV mode.
Whenever a Jog Lever is activated, a large “J” is displayed in the upper left corner of the
Control Head’s screen (see Figure 71) – temporarily replacing the current mode’s indicator
letter.
The jog Levers are ignored when the autopilot is in STANDBY mode, or in DOCKSIDE
SETUP mode.
Caution! You should always be prepared for a change in the vessel’s direction when you
release the Jog Lever.
