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. [. . . ] Note: The High wind speed alarm screen is available only on master instruments. It is a temporary screen and will time-out to the previous permanent screen (Apparent wind or True wind) after 5 seconds.

1. 3 Screen descriptions
Apparent and true wind screens
Boat heading Wind angle Either A (apparent) or T (true)
Wind direction with respect to boat heading. Either apparent or true.
Wind speed Either apparent or true, as indicated above. If apparent wind information is displayed, press to apply the current wind bearing as the locked heading
D4792-2
Locked apparent wind screen
Flashing segment indicates the divergence of the apparent wind from the locked wind angle
STEER
Locked wind angle P = port, S = starboard. Relative direction of the locked wind angle
Apparent wind speed
Direction to steer indicator to achieve locked wind angle
Use or to change locked wind angle, as required. Press to return to the Apparent wind screen
Note: In auto lock mode, a similar screen is displayed with an A LOCK annunciator, to indicate that the locked wind angle is controlled by the course computer and cannot be changed manually.

1. 4 High wind speed alarm
The high wind speed alarm threshold is set up at the Set high wind speed alarm threshold screen and the alarm sounds if the alarm is switched on and the wind speed exceeds this threshold.

WIND
D4754-2
True wind
If boat speed information is available at the ST40 Wind instrument (from a SeaTalk bus), the alarm is triggered if TRUE wind speed exceeds the threshold.
Apparent wind
If boat speed information is not present, the alarm is triggered if the APPARENT wind speed exceeds the threshold.
Enabling/disabling alarm
You can enable or disable the high wind speed alarm function (i. e. switch it on or off ) by selecting the Set high wind speed alarm threshold screen (see Normal operation) and holding down the key for 3 seconds (toggle action).

2. 1 Maintenance
Servicing and safety
· Raymarine equipment should be serviced only by authorised Raymarine service technicians. 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. Low battery Action Recharge your vessel's battery as soon as possible

Chapter 3: Installation
This chapter describes how to install the ST40 Wind instrument, and associated Rotavecta wind transducer.
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. In the case of SSB radios, the distance should be increased to 2 m (7 ft). A radar beam can normally be assumed to spread 20 degrees above and below the radiating element.

ST40 Wind 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. [. . . ] SeaTalk is a proprietary Raymarine system which links different compatible products, to provide a single, integrated navigational system. SeaTalk can also communicate with non-SeaTalk equipment using the internationally- accepted National Marine Electronics Association (NMEA) protocol. Contact your Raymarine dealer for details.
