Clearance pre-warning: These alarms are used to warn you if a

trawl or another towed object either moves too close to the

bottom, or lifts too f ar off the bottom. You must have the echo

sounder switched on to use this alarm. To enable it, set the

minimum limit to the minimum allowed distance between the

footrope and the bottom, and/or the maximum limit to the

maximum allowed distance between the footrope and the

bottom. Then, switch one or both alarms to ON. The alarm is

triggered if the reading from a Depth sensor mounted on the

footrope (or a manual depth marker) exceeds one of the defined

limits. To use this alarm for a single towed object, select the

Depth sensor as a Foot rope sensor in the Trawl info dialogue.
