8 Troubleshooting
Users who primarily use acoustic location can sometimes locate
actitiouslineCbetweenlineAandlineB.
It is possible to avoid this error by checking carefully the direc-
tional arrows on the display. The directional arrows show the
direction in which a line is located. Directly over a line the direc-
tional arrows turn into a diamond. As C is not a line, no diamond
appears.
