2.1.2 ATTACHING HYDROPHONE TO ANGLE MOUNT
The hydrophone centerline, or zero bearing, is indicated by the index mark (mark is just above the
potted section of the hydrophone which is aligned with the slot in the pressure case as opposed to
the pin which faces aft or 180 from bow reference) and is generally aligned so that it corresponds
to the vessel heading. Most operations requiring a portable tracking system will be on various ves-
sels of opportunity, and require a quick and temporary mounting. See Figure 2-2 and 2-3 for a typ-
ical hydrophone mounting arrangement.
Fasten the hydrophone, Model 4213C, to an angle bracket (not supplied), (see Figure 2-4 Hydro-
phone Mount Angle Bracket, 4213BM0010 as an example) aligning the slot in the PVC base with
the “V” in the bracket. Using screw clamps secure the hydrophone to the proposed angle bracket.
Align the screw clamps with the grooved areas on the hydrophone case.
Feed the deck cable, Model 4113C or 4113C-DT, through the hydrophone extension pipe.
Connect the deck cable to the hydrophone. See Figures 2-5 and 2-6 for the Model 4113C and
4113C-DT cable assemblies.
The Deck Cable mates to the Hydrophone by lining up the pins in both connectors and pushing to-
gether. The mated connection is then held together with the locking sleeves. The following are
guidelines from the manufacturer.
 Align indexes on connectors and mate with minimum twisting and flexing
 Care must be taken not to damage contacts in unmated connectors
 Contact surfaces must be dry prior to mating.
 Lubricate mating surfaces with 3M Silicone Spray or equivalent* (see caution below). DO
NOT GREASE. Connectors must be lubricated on a regular basis.
 Avoid contact with solvents.
 Grip main body of connector during mating or unmating. Do not pull on the cable to discon-
nect.
 Avoid sharp bends at cable entry to connector.
 Elastomers can be seriously degraded if exposed to direct sunlight or high ozone levels for
extended periods of time.
