                     FSB-006 - TRANSDUCER CARE (HANDLING)
                  DATE/REV:  12APR89 / 0 (previously FSB 1-6)
==============================================================================

ABSTRACT:  Describes care and handling procedures for all ADCPs.

INSTRUMENT/PROGRAM AFFECTED:  All ADCPs.

DESCRIPTION:  Dents in the perimeter of the transducer cups or at the edge of
the urethane coating can cause a leak.  If a leak occurs, the entire system is
at risk.

SOLUTION/ACTION:  Use the following precautions when handling ADCPs.

a.  Never rest the transducer directly on a hard or rough surface.  Always
    rest the transducer on a foam pad or cushion.

b.  When deploying/retrieving the ADCP, do not bang the transducer into hard
    objects.

c.  Inspect the transducer for dents before and after each deployment.

d.  If in doubt about the extent of the damage, call RDI.
