* When mating connectors DO NOT allow any silicone spray (or grease) to contact the
black potting of the hydrophone. Should silicone come in contact with the hydrophone
potting, proper sound transfer from water to hydrophone will be prevented. Attempting to
remove silicone from the hydrophone can damage the potting material.
NOTE: If you are using an extension pipe with a sufficient inside diameter to allow the hydro-
phone cable to be fed through to the hydrophone, remember to run the cable through the
pipe before placing the 1/2-inch (13-mm) bolts in the mounting holes, as the connector
may not pass through when the bolts are in place. When drilling the lower hole, keep in
mind that you need enough space between the end of the pipe and the connector on the
top of the hydrophone itself to connect and disconnect the cable. For this reason, we rec-
ommend that the lower mounting hole be no more than two inches (5 cm) from the end
of the pipe.
Fasten the hydrophone and angle bracket to the extension pipe. Use screw eyes or other fasteners
for fore and aft guy attachments.
Using the "V" of the angle bracket as a guide, align the hydrophone (mark is facing forward) with
the vessel centerline as closely as possible. Lock in place.
Use some variation of the procedure in 2.4.1 to remove hydrophone bearing offset.
