USING YOUR PROPILOT 725
The Autopilot Control
This is the unit where you, the Helmsman, tell your autopilot
what you require is to do for you.
It communicates to you using an 8 digit Liquid Crystal Display
(LCD), a Light Emitting Diode (LED) and its internal audible
alarm. You communicate with it using the 14 keys and the
rotary Course Selector Knob.
Remember Inan EMERGENCY press OFF to regain manual control.
Getting Started The autopilot has 2 basic modes of operation.
1. Standby Mode where the autopilot is switched on but not
in control of the vessel.
2. Auto Mode where the autopilot is in control of the vessel.
The ON/ST’BY key turns the autopilot on. There will be a
delay of about 10 seconds while the autopilot checks itself. If
it detects something is wrong it will display an error message.
These are explained in the section on Error and Fault Displays
in the Installation and Servicing Manual.
HEAD 035 Usually all will be OK so the LCD displays HEAD to tell you
the autopilot is in Standby Mode and is displaying the vessel’s
heading (035º in this example). This changes as you steer,
just like a conventional compass. The autopilot is not in
control of the vessel.
The AUTO key now switches the autopilot from Standby to
Auto Mode which puts the autopilot in control of the vessel’s
course.
Full stops within the LCD text align with a sub-menu at the
base of the LCD to indicate whether the autopilot is under
Navigator Control (NAV 1/NAV 2), if the Gyro is operational, if
Power Steer is on or if a Compass Variation is entered. In
addition flashing points above the directional arrows indicate
that the vessel is off course.

PROPILOT 725 USER’S GUIDE
-6- 807-251-1-96
C.OMP 08.1 The LCD displays COMP to tell you the autopilot is in Auto
Mode, steering from a compass, steering the course displayed
(081º in this example).
So you could simply turn your autopilot on, steer to the
heading you want to maintain then switch to Auto Mode
letting the autopilot hold that course until you tell it
otherwise. This method is termed Autofollowing.
Changing Course
Changing course is just as simple. You could switch your
autopilot back to Standby Mode, steer to the new course
manually then switch back to Auto Mode.
COMP 091 Alternatively, if you are in Auto Mode you can just rotate the
Course Selector Knob until the new course is displayed on the
LCD. The autopilot will then bring the vessel to the new
course for you.
Pre-selecting a Course
You may pre-select a course while the autopilot is in Standby
Mode. Simply rotate the Course Selector Knob.
CTS 120 The LCD will display CTS so that you know the reading is no
longer your heading but the autopilot’s Course To Steer. The
numbers indicate the heading that the autopilot will steer the
vessel to if you press the AUTO key and put the autopilot
into Auto Mode.
WARNING This can cause a very sudden and severe course change if
the Course to Steer is a lot different from the current
course.
When you put the autopilot into Auto Mode the LCD will
change from CTS to COMP.
Course Dodging
When you are in Auto Mode and you press the or key
the vessel will turn and continue to turn until you release the
key. The autopilot will then return you to its preset heading.

This function is used to sidestep small obstacles in the vessel’s
path and will return you to a parallel track from your original.
The internal alarm will sound and the warning light will
illuminate while the key is being pressed.
Press the key and the display will indicate a dodge to Port
(left) and the vessel will turn to Port.
Press the key and the display will indicate a dodge to
Starboard (right) and the vessel will turn to Starboard.
Using Two Courses
There is a function which allows the Helmsman to quickly
and easily alternate between two courses, ideal for tacking
sailing vessels.
PREV 127 Each time the AUTO key is pressed, the autopilot remembers
the course prior to the press of the key. This course can then
be recalled by pressing the FUNCT key once. The LCD will
display the prefix PREV to tell you that it is the previously
stored course.
COMP 127 Pressing the AUTO key will instruct the autopilot to follow
this new course and at the same time store the old course.
PREV 213 Pressing the FUNCT key once again will display the
previously stored, or old, course.
COMP 213 Pressing the AUTO key will instruct the autopilot to follow
this course and at the same time store the previous course.
So by following this simple sequence the Helmsman can
alternate between two courses as often as he likes.
If you press the FUNCT key and the previously stored course
is not the one that you wish to use, you can change it:
a) by rotating the Course Selector Knob until the required
course is displayed, or
b) by pressing either the or key to enter the current
heading.

ALARMS
The autopilot has its own internal audible alarm and a red
visual alarm that will light up. You may also connect further
external alarms to the autopilot system.
There are three alarms that can be set by the Helmsman, an
Off Course Alarm, a Watch Alarm and a Timed Alarm.
Off Course Alarm
This alarm will trigger after the vessel has been off course by
more than the set amount, for a period of 30 seconds. The
alarm will be triggered instantly if the vessel is off course by
more than twice the set amount.
OC ALARM When the alarm triggers, the LCD will display the Off Course
Alarm message. Once the vessel is back on course the alarm
will cancel, it cannot be manually cancelled.
Setting the Off Course Alarm
OCAL--00 Press and hold the ALARM key to enter the alarm options,
the Off Course Alarm setting is the first option and will be
displayed immediately. The right had two digits indicate the
number of degree’s the vessel may go off course before the
alarm is triggered. The OCAL--00 value is the alarm’s
default setting and represents a maximum setting of 20º, the
Off Course Alarm cannot be switched off.
OCAL¦15 To set a higher value, press the key and the set value will
increase. An arrow will also appear to confirm the value is
increasing.
OCAL§10 Press the key and the value will start to decrease. An
arrow will confirm that the value is decreasing.
The value displayed is the one that the autopilot will use. The
ALARM key will step through the other alarm settings or the
AUTO or ON/ST’BY keys will take you back to the
appropriate displays.

SFIA Versions The SFIA (Sea Fish Industries Authorities) version includes a
Watch Alarm and Power Fail Alarm that comply with the SFIA
regulations and therefore cannot be disabled.
Watch Alarm
*WATCH** Ifthe autopilot is in Auto Mode and a key has not been
pressed after four minutes the alarm is activated. This display
indicates that the watch alarm has been triggered and is
accompanied by the integral low level audible alarm. If this is
not reset by pressing the ALARM key within one minute, an
external high level audible alarm will sound.
*RESET* Toreset the high level alarm, press either the or key.
Note: ALARM can be pressed at any time before the alarm
sounds, at which point the alarm cycle is reset.
Power Fail Alarm
The external, high level alarm shares the autopilot’s primary
supply but has an independent secondary supply. In the
event of a power failure of either the primary or secondary
supplies, the audible alarm will sound.
PWR FAIL If the secondary power supply fails, the display PWR FAIL
can be cleared by pressing either the or key. The
audible alarm can only be cancelled by restoring the
secondary power supply.
If the primary power supply fails, the autopilot also switches
off and the display will be blank. The external audible alarm

SEA STATE ADJUSTMENTS
As conditions around you vary, it is best to optimise how
your autopilot reacts in order to obtain optimum
performance. The two settings RESPONSE and RUDDER
should enable you to fine tune the autopilot’s performance to
most conditions.
Proper setting of these controls has a marked effect on
steering system wear and tear and in sailing craft, also upon
battery life. Aim to set these controls so that the autopilot-
controlled helm movements are of roughly the same
frequency and magnitude as those performed by hand when
steering manually.
Selecting Pilot A, B or C
You can store three sets of Sea State adjustments, called
PILOT A, PILOT B and PILOT C. These enable the
autopilot to be tuned for differing speeds and sea conditions.
They are linked to the Configuration Settings which are
explained in the Installation and Servicing Manual.
To select a pilot set press the MODE key.
PILOT A The set which the autopilot is currently using will be
displayed.
PILOT B Press the MODE key and the alternative sets are displayed,
once displayed these are automatically selected.
You may change any of the settings and the autopilot will use
them but it will not store them until the unit is turned off by
the OFF key.
Rudder Ratio The Rudder Ratio setting is used primarily to match rudder
movement to boat speed. Generally the higher the speed,
the lower the setting needs to be.
If the setting is too low the vessel will understeer and tend to
drift off course to one side.
Sea State Adjustments

PROPILOT 725 USER’S GUIDE
-17-
807-251-1-96
If the setting is too high the vessel will oversteer and build up
oscillations from side to side.
To Adjust the Rudder Setting
Use the MODE key to select Pilot A, B or C then press the
SEA STATE key and the LCD will show the rudder setting.
RUD--05 Thesetting will be between 0 and 20.
Change the setting by using the or key.
RUD¦08 Press the key and the setting value begins to increase.
An arrow on the display confirms that it is increasing.
RUD§06 Press the key and the setting value begins to decrease.
An arrow on the display confirms that it is decreasing.
Response (Yaw) The Response setting, also known as the Yaw setting, is
primarily the autopilot’s “weather” control. It sets the
amount that the vessel is permitted to move off course before
rudder is applied to bring it back onto its set heading.
You may need to open the Response (ie increase the setting
value) in heavy seas and close it (ie decrease the setting value)
in calm seas.
If the Response setting is too high the vessel moves a long
way from the course before it is corrected. You will need to
decrease the Response setting to overcome this.
If the Response setting is too low the vessel will hold its
course but the helm will be constantly and rapidly moving,
making small unnecessary corrections. You will need to
increase the Response setting to overcome this.
To Adjust the Response Setting
Select Pilot A, B or C using the MODE key and then press the
SEA STATE key two times, the LCD will show the Response
setting.
Sea State Adjustments

PROPILOT 725 USER’S GUIDE
-18- 807-251-1-96
RESP--07 The setting will be between 0 and 20.
Change the setting by using the or key as detailed in
the Rudder Ratio section above.
Pulse Width Modulation
Also accessible within this group of settings is the Pulse Width
Modulation (PWM). This is a method of controlling the
steering motor of the vessel’s drive unit, so that it gives a
smoother rudder operation, especially useful if the vessel has
a high steering inertia. It can however, generate RFI (Radio
Frequency Interference) in some instances and so there is a
simple means of switching it off if necessary.
PWM-ON The third press of the SEA STATE key will display the status
of the PWM setting. It can only be ON or OFF. Pressing
either the or key will change the setting.
For all settings, the value displayed is the one that the
autopilot will use. Pilot A settings can be set different to Pilot
B or Pilot C settings.
The SEA STATE key will step through the other Sea State
adjustments, alternatively the AUTO or ON/ST’BY keys will
take you back to the relevant displays.
Remember... ..changed settings will only be stored if the autopilot is
turned off using the OFF key.

NAVIGATOR CONTROL
Using Navigator Control
Connection and message format selection information for the
Navigator are given in the Installation and Servicing Manual.
Ensure that the autopilot is programmed to receive the
correct format messages.
In the event of the Navigator indicating an alarm condition,
the autopilot will display NAV DATA on the LCD. The
autopilot will hold the vessel on its present heading and will
not accept any further changes until this error is cleared.
(Note: the Navigator should also indicate this alarm
condition.) To clear the above alarm from the autopilot, press
any key except , or OFF. If the alarm clears the
autopilot will accept data. If the above condition still exists,
turn the autopilot off and resume autopilot control under
Compass Control or manually steer the vessel.
