• If Cross Track Error data is being received, but no
Bearing To Waypoint data, then the display will show
“– – –” instead of the Bearing To Waypoint.

2.5 Set Key

The

Set

key performs several functions, including adjust-

ing the parameters of the AP14 such as seastate, dodge
angle etc. Refer to the relevant sections for more infor-
mation on these.

In addition, depending on the NMEA data being received
by the AP14, the following data can be displayed by
pressing the

Set

key the specified number of times -

Press SET

Data Shown

Cross Track Error [

XTE

] (Fig 2.5)

Bearing To Waypoint [

] (Fig 2.6)

Distance To Waypoint [

] (Fig 2.7)

• The individual data will only be shown if it is being
received from the navigational receiver, so for example, if
BTW is not being received, the second press will show
DTW. Subsequent presses of the

Set

key will access func-

tions in the following order -

SEASTATE SETTING

(Section 3.2)

OFF COURSE ALARM ANGLE

(Section 2.8)

DODGE ANGLE

(Section 2.10)

DEFAULT BOAT SPEED

(Section 2.9)

2.3 Adjusting Course

While in Autopilot Mode, precise course adjustments can
be easily made -

• Press the

key once to make a 1º course adjust-

ment, confirmed by one beep and on the display by the
new heading shown

• Press and hold the key for a 10º course change, con-
firmed by a double beep and on the display by the new
heading shown (Fig 2.3).

2.4 Nav Mode

The AP14 has an inbuilt interface which allows it to be
connected to NMEA0183 compatible equipment such as
GPS, LORAN, Chart Plotters etc.

Once connected, the AP14 can steer using data from this
source in addition to the compass, allowing a highly accu-
rate course to waypoint

• To enter Nav Mode the pilot must be in Auto Mode and
receiving waypoint or route data from the navigational
receiver.

Press

Nav

to activate Nav Mode (Fig 2.4). The display will

show NAV and the pilot will steer to the first waypoint.

• If no NMEA information is being received, the AP14
will beep twice and will not enter Nav Mode.

• If

Nav

is pressed while in Standby mode, the pilot will

beep once if Nav Mode is available when in Auto Mode,
or twice if Nav Mode will not be available.

At the target waypoint, an intermittent alarm will sound.
As a safety feature (to avoid an unexpected course
change) the next waypoint will not be loaded until the

Nav

key is pressed again. When the boat reaches the final

waypoint, the pilot will switch back to Auto Mode, hold-
ing the current course.

Note - If a course correction is made while in Nav Mode
using the

and

keys, the boat will gradually return to

the original track, so that the boat can avoid an obstacle
without exiting Nav Mode or having to reset the boat on
the correct course.

Pressing

Nav

when in Standby mode will bring up the

current Bearing To Waypoint (BTW) on the display.
