Preface i
Important information
WARNING
Although your ST40 instrument is designed to give accurate and
reliable performance, it should serve only as an aid to navigation
and should never lead to the erosion of good seamanship. Always
maintain a permanent watch and be aware of situations as they
develop.
EMC conformance
All Raymarine equipment and accessories are designed to the best
industry standards for use in the leisure 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, the Raymarine policy of
continuous product improvement may change product specifications
without notice. Consequently, unavoidable differences may occur
between the product and the handbook from time to time, for which
Raymarine cannot accept liability.

Chapter 1: Operation 1
Chapter 1: Operation
1.1 Introduction
Your ST40 Bidata instrument:
• Provides speed information (current, maximum and average), in
either knots (KTS), miles per hour (MPH) or kilometres per
hour (KPH).
• Provides log and trip information. These are given in either nautical
miles (NM), statute miles (M) or kilometres (KM).
• Provides water temperature information. This is given in either
degrees Celsius (°C) or degrees Fahrenheit (°F).
• Provides depth information in either feet (FT), metres (M) or
fathoms (FA).
• Records the minimum depth encountered during the period it is
switched on. You can reset this at any time.
• Enables you to define alarm thresholds for shallow water, deep
water, shallow anchor and deep anchor.
• Enables you to see what offset is applied to the depth reading.
Note: The required speed, distance, depth 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.
Display
The ST40 Bidata display comprises upper and lower data areas, each of
which shows either depth or speed information, selected as shown in
the following illustration.

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:
• Up/down depth-trend arrows are displayed, if the seabed is rising or
falling at a significant rate.
• The minimum depth reading is reset to zero at power up.
• 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 Bidata instrument was fitted.
• The trip reading is reset to zero at power up.
Display action
During normal operation (see Normal operation flow charts), the
Speed, Depth and Water temperature screens are permanent
screens, i.e. once one of these is selected, it will remain until another
screen is manually selected. All other screens are temporary and after
5 seconds, will time out to the permanent screen which was last
displayed for 5 seconds or more.
Silencing alarms
To silence an alarm (see the Alarms section, later in this chapter),
momentarily press any one of the instrument keys.

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.
159_2c02.p65 01/05/01, 15:149

10 ST40 Bidata Instrument Owner’s Handbook
Periodically clean your ST40 instrument with a soft damp cloth. Do
NOT use chemical or abrasive materials to clean the instrument.
Transducers
Refer to the Installation and Maintenance instructions supplied with the
transducers.
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.
Action
Recharge your vessel’s battery as
soon as possible
