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.
