Chapter 1: Operation
1.1 Introduction
Your ST40 Speed instrument provides:
• Speed information (current, maximum and average), in either knots
(KTS), miles per hour (MPH) or kilometres per hour (KPH).
• Log and trip information. These are given in either nautical miles
(NM), statute miles (M) or kilometres (KM).
• Water temperature information. This is given in either degrees
Celsius (°C) or Fahrenheit (°F).
Note: The required speed, distance and water temperature units are
selected during User calibration (see Chapter 4, Calibration).
CAUTION
Your instrument is calibrated to factory (default) settings when
first supplied and must therefore be calibrated before use, to
ensure optimum performance on your vessel. Do NOT use the
instrument until the calibration procedures have been
satisfactorily completed, using the procedures in Chapter 4,
Calibration.
Coloured bezel and Desktop Mounting Bracket options are available
for your ST40 instrument. Contact your Raymarine dealer for further
information.
1.2 Operating procedures
Operating information is presented in flow chart form. The flow charts
show the various operating screens and key presses necessary to carry
out the various instrument functions. Key presses are momentary unless
otherwise stated.
Note that:
• The maximum speed reading is reset to zero at power up.
• The average speed reading is reset to zero at power up.
• The Log screen shows the total distance covered by the vessel since
the ST40 Speed instrument was fitted.
• The trip reading is reset to zero at power up.

Chapter 2: Maintenance and Fault Finding
2.1 Maintenance
Servicing and safety
•Raymarine equipment should be serviced only by authorised
Raymarine service technicians. They will ensure that service
procedures and replacement parts used will not affect performance.
There are no user-serviceable parts in any Raymarine product.
•Some products generate high voltages, so never handle the cables/
connectors when power is being supplied to the equipment.
•When powered up, all electrical equipment produces
electromagnetic fields. These can cause adjacent pieces of electrical
equipment to interact with one another, with a consequent adverse
affect on operation. In order to minimise these effects and enable
you to get the best possible performance from your Raymarine
equipment, guidelines are given in the installation instructions, to
enable you to ensure minimum interaction between different items
of equipment, i.e. ensure optimum Electromagnetic Compatibility
(EMC).
•Always report any EMC-related problem to your nearest Raymarine
dealer. We will use any such information to improve our quality
standards.
•In some installations, it may not be possible to prevent the
equipment from being affected by external influences. In general
this will not damage the equipment but it can lead to spurious
resetting action, or momentarily may result in faulty operation.
•Always switch off the power to Raymarine equipment before
working on it.
When requesting service, please quote equipment Type, Model
Number, Serial Number and, if possible, Software Release Issue. The
Software Release Issue can be ascertained by means of the
Intermediate Calibration facility, see Chapter 4, Calibration.

Instrument
Certain atmospheric conditions may cause a small amount of
condensation to form on the instrument window. This will not harm the
instrument and will clear after the instrument has been switched on for a
short period.
Periodically clean your ST40 instrument with a soft damp cloth. Do
NOT use chemical or abrasive materials to clean the instrument.
Transducer
Refer to the Installation and Maintenance instructions supplied with the
transducer.
Cabling
Examine all cables for chafing or other damage to the outer shield and,
where necessary, replace and re-secure.
2.2 Fault finding
Preliminary procedures
If you appear to have a problem, first check the security of the
connections at the rear of the instrument and reconnect any that are
loose.
Changes in the electronic environment may adversely affect the
operation of your ST40 equipment. Typical examples of such changes
are:
•Electrical equipment has recently been installed or moved aboard
your vessel.
•You are in the vicinity of another vessel or shore station emitting
radio signals.
Fixing faults
All Raymarine products are subjected to comprehensive test and
quality assurance programmes prior to packing and shipping. However,
if a fault occurs, the following guidelines may help to identify and
rectify the problem.

Chapter 3: Installation 9
Chapter 3: Installation
This chapter describes how to install the ST40 Speed instrument, and
associated speed transducer. The transducer is fitted in the hull of the
vessel and is connected to the rear of the instrument.
3.1 Planning your installation
Determine the best positions for both transducer and instrument, such
that the EMC installation guidelines and the Site requirements (below)
are satisfied.
EMC installation guidelines
All Raymarine equipment and accessories are designed to the best
industry standards for use in the leisure marine environment.
Their design and manufacture conform 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.
The guidelines given here describe the conditions for optimum EMC
performance, but it is recognised 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:
•All Raymarine equipment and cables connected to it are:
•At least 1 m (3 feet) 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 2 m
(7 ft).
•More than 2 m (7 ft) from the path of a radar beam. A radar beam
can normally be assumed to spread 20 degreesabove and below
the radiating element.
157_2c03.p65 01/05/01, 12:229

10 ST40 Speed Instrument Owner’s Handbook
•The equipment is supplied from a different battery from that used for
engine start. Voltage drops below 10 V in the power supply to our
products, 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 at all times. Cutting and
rejoining these cables can compromise EMC performance and so
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.
Suppression Ferrites
The following illustration shows typical cable suppression ferrites fitted
to Raymarine equipment. Always use the ferrites supplied by
Raymarine.
D3548-2
Connections to Other Equipment
If your Raymarine equipment is going to be connected to other
equipment using a cable not supplied by Raymarine, a suppression
ferrite MUST always be fitted to the cable close to the Raymarine unit.
Tools required
The tools required for fitting the standard ST40 instrument system are
shown in the following illustration.

The transducer should:
•Be ahead of the propellers (by a minimum of 10% of the water line
length ).
•Be at least 150 mm (6 in) away from the keel (ideally ahead of the
keel if a sailing yacht).
•Be as near as possible to the centre line of the vessel.
•Be clear of other through-hull fittings or projections.
•Have sufficient clearance inside the hull to fit the nut.
•Have 100 mm (4 in) of headroom to allow for withdrawal.
The transducer should be sited within the clear water flow areas
indicated by the shaded areas in the following diagram.
