Safety notices
WARNING: Product installation
This equipment must be installed and operated in accordance
with the instructions contained in this handbook. Failure to do so
could result in poor product performance, personal injury
and/or damage to your boat.
WARNING: Electrical safety
Make sure the power supply is switched off before you make any
electrical connections.
WARNING: Calibration
We supply this product calibrated to default settings that should
provide stable performance for most boats. To ensure optimum
performance on your boat, you must complete the procedures
detailed in the Commissioning section of the handbook for the
relevant Autopilot controller.
WARNING: Navigation aid
Although we have designed this product to be accurate and
reliable, many factors can affect its performance. As a result, it
should only be used as an aid to navigation and should never
replace common sense and navigational judgement. Always
maintain a permanent watch so you can respond to situations as
they develop.

Your Raymarine autopilot will add a new dimension to your boating
enjoyment. However, it is the skipper’s responsibility to ensure the
safety of the boat at all times by following these basic rules:
• Ensure that someone is present at the helm AT ALL TIMES, to
take manual control in an emergency.
• Make sure that all members of crew know how to disengage the
autopilot.
• Regularly check for other boats and any obstacles to navigation –
no matter how clear the sea may appear, a dangerous situation can
develop rapidly.
• Maintain an accurate record of the boat’s position by using either
a navigation aid or visual bearings.
• Maintain a continuous plot of your boat’s position on a current
chart. Ensure that the locked autopilot heading will steer the boat
clear of all obstacles. Make proper allowance for tidal set – the
autopilot cannot.
• Even when your autopilot is locked onto the desired track using a
navigation aid, always maintain a log and make regular positional
plots. Navigation signals can produce significant errors under
some circumstances and the autopilot will not be able to detect
these errors.
EMC conformance
All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environment.
The design and manufacture of Raymarine equipment and
accessories conform to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to
ensure that performance is not compromised.
Handbook information
To the best of our knowledge, the information in this handbook was
correct when it went to press. However, Raymarine cannot accept
liability for any inaccuracies or omissions it may contain. In addition,
our policy of continuous product improvement may change
specifications without notice. As a result, Raymarine cannot accept
liability for any differences between the product and the handbook.

EMC installation guidelines
All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environment.
Their design and manufacture conforms to the appropriate
Electromagnetic Compatibility (EMC) standards, but correct
installation is required to ensure that performance is not
compromised.
Although every effort has been taken to ensure that they will perform
under all conditions, it is important to understand what factors could
affect the operation of the product.
81131_8.book Page 36 Thursday, October 7, 2004 11:03 AM
The guidelines given here describe the conditions for optimum EMC
performance, but it is recognized that it may not be possible to meet
all of these conditions in all situations. To ensure the best possible
conditions for EMC performance within the constraints imposed by
any location, always ensure the maximum separation possible
between different items of electrical equipment.
For optimum EMC performance, it is recommended that wherever
possible:
• Raymarine equipment and cables connected to it are:
• At least 3 ft (1 m) from any equipment transmitting or cables
carrying radio signals e.g. VHF radios, cables and antennas.
In the case of SSB radios, the distance should be increased to
7ft(2m).
• More than 7 ft (2 m) from the path of a radar beam. A radar
beam can normally be assumed to spread 20 degrees above
and below the radiating element.
• The equipment is supplied from a separate battery from that used
for engine start. Voltage drops below 10 V, and starter motor
transients, can cause the equipment to reset. This will not damage
the equipment, but may cause the loss of some information and
may change the operating mode.
• Raymarine specified cables are used. Cutting and rejoining these
cables can compromise EMC performance and must be avoided
unless doing so is detailed in the installation manual.
• If a suppression ferrite is attached to a cable, this ferrite should not
be removed. If the ferrite needs to be removed during installation
it must be reassembled in the same position.

Wheel drive (wheel pilots only)
The Raymarine wheel drive will fit 3, 4, 5, 6, 7 or 8 spoke wheels. It is
designed to operate with steering systems with between 1 to 3.5 turns
lock to lock.
Installation stages
Installing the wheel drive involves four stages:
1. Drilling the spoke clamp holes in the front cover.
2. Securing the wheel drive to the wheel.
3. Attaching the pedestal bracket.
4. Connecting the drive to the control unit.

Drilling the spoke clamp holes
1. Remove the wheel drive front cover:
• the front cover is held onto the wheel drive by three ‘push-fit’
posts which sit in three sockets on the drive ring
• to remove the cover, hold the motor in one hand and use your
other hand to pull the cover up and away from the drive unit
(as shown below)
2. Identify the appropriate spoke clamp holes for your wheel. With
the arrow at the top, refer to the following diagrams:
• the holes are numbered inside the cover (e.g. if you have a 5
spoke wheel, you need to drill the 4 locations marked with ‘5’)
• mark the appropriate spoke clamp holes and check them by
holding the cover against your wheel
