Preface

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

Chapter 1: Operation

1.1 Introduction

Your ST40 Compass instrument:

• Provides true and magnetic bearing information.

• Enables a locked bearing to be defined either manually, or
automatically by a course computer. In this mode, the instrument
shows the deviations from the locked bearing and the direction to
steer to achieve the locked bearing.

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.

Silencing alarms

To silence an alarm (see the Alarms section, later in this chapter),
momentarily press any one of the instrument keys.
