Chapter 1: Operation 1

Chapter 1: Operation

Your ST40 Depth instrument:

• Provides depth information, in either feet (FT), metres (M) or

fathoms (FA), as set during User calibration (see Chapter 4,

Calibration).

• 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.

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.

1.1 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.

Silencing alarms

To silence an alarm (see the Alarms section, later in this chapter),

momentarily press any one of the instrument keys.
