Chapter 1: Operation
1.1 Getting started
This handbook describes how to operate, maintain and install the Raymarine
ST60 Depth instrument.
CAUTION: Calibration requirement
The ST60 Depth instrument is calibrated to default settings when
supplied. To ensure optimum performance on your boat, this
product MUST be calibrated before use. Do NOT use the product
until it has been calibrated using the procedures in Chapter 4,
Calibration.
1.2 Normal operation
Use the flow charts in this Chapter to operate your ST60 Depth instrument. The
flow charts show the sequence of key presses and displays for the various
operating tasks. All key presses are momentary unless otherwise stated.
Depth measurement units
The depth measurement units can be either feet, meters or fathoms. The required
units are selected during user calibration (see
Chapter 4, Calibration
).
Displayed information
When first switched on, your ST60 Depth instrument shows the current depth. The
instrument memorizes the minimum and maximum depth values encountered
during the period it is switched on, and these can be recalled at any time (see the
Reading depth values
flow chart).
The display will revert to the current depth display after 8 seconds.
You can reset the MIN and MAX values by pressing the
reset key for 3 seconds.
The current depth display provides depth-trend indicator arrows to show whether
the depth is increasing or decreasing. A rising sea-bed is shown by an up arrow
and a lowering sea-bed by a down arrow.
If there is no depth signal from the transducer for more than 30 seconds, the last
known depth is displayed and LAST flashes at the top of the screen. If depth
information is not received from the transducer or from SeaTalk, then dashes are
displayed.
