Standby Menu
The Standby menu consists of a number of items that have a general bearing on how the
autopilot operates. To access the Standby menu, double-press the red STANDBY/ON/OFF
button.
Figure 56 – Standby Menu (pages 1, 2, and 3)
Station Lock
The P4 system can accommodate up to three Control Stations; one main Control Head, and
any combination of Control Heads and Remotes on the two AUX ports.
One of these Control Stations is always the main control, and the others are simply repeater
stations. You can take command with any of the repeater stations by simultaneously pressing
the PORT and STARBOARD ARROW buttons on the repeater.
However, to prevent an unauthorized person from doing this, the main Control Head can lock
out all of the others. Station Lock must be changed to Unlock before the repeater stations can
take command. For more detail, refer to Station Lock/Unlock section of this manual.
Default Turn
The P4 System has a number of Special Turns pre-programmed into it. The variety of turns
available depends somewhat on the system configuration and what mode you are operating
in.
Set the Default Turn parameter to the type that you are likely to use most often. Then, when
you press the TURN button to initiate a Special Turn, the default turn will be the first one
offered.
Compass Source
There are a number of separate inputs for the many different types of compasses that may
be used with the P4 (N2000, Analog, Nav1 and Nav2) system. You may choose to have more
than one type connected at any given time. This menu item allows you to switch from one to
another whenever the operator chooses.
The selected input can be the same one used for the Navigation data source and/or the
Speed source.
Compass Cal - Compass Calibration
This feature allows you to synchronize the compass on the autopilot with an external source.
Simply turn the COURSE CHANGE knob until the Compass Cal value reads the same as
your reference source.
NOTE: For safety reasons, Compass Cal may not be adjusted in AUTO or NAV modes,
so it does not appear if the Standby menu is entered in one of those modes.
