Resetting depth values

To reset the minimum depth or maximum depth value:

1. In the Depth chapter, select the appropriate page (MIN DEPTH or MAX

DEPTH, as appropriate).

2. Hold down the button for 2 seconds. After 1 second the displayed

value flashes and after 2 seconds, it resets to the current depth

reading.

Depth transducer offset

Depths are measured from the Depth transducer to the seabed. During

setup, a depth transducer offset can be applied to the actual distance

measured, so that the displayed depth reading represents the depth either

from the waterline (positive offset) or from the bottom of the keel

(negative offset).

This is the value displayed on the DP OFFSETpage.

WARNING:

The use of incorrect offset values could result in misleading depth

information being displayed with a consequent risk of running

aground.

Before using your ST290 system, ensure the correct depth transducer

offset has been set, as detailed in Section 7, System Setup.
