Step 3 - Hand tighten the end cap
Reposition the HR2 so the hydrophone (top end) is hanging over
the edge enough that the large hole is past the edge of the surface.
DO NOT let the receiver fall off the surface.
Hold the body of the HR2 securely in place.
Hand tighten
the end cap in a clockwise direction until the cap
and outer cylinder are fairly tight.
WARNING: DO NOT impact the threads on the end-cap or
they will dent and prevent the case from closing. For tips on
thread care, see
"The Threads Have Been Damaged", on
page 176 .
Step 4 - Prepare for final tightening
Place a hand on the back of the receiver or steel rod to hold
it in place.
Step 5 - Insert the steel rod - Top end
Hold the body of the HR2 securely in place.
Insert the steel rod into the hole at the top end of the
receiver and hold on to the rod – it can slide right through
the hole and potentially damage something below.
Make sure the rod is inserted through to the other side –
damage may occur to the hole if the rod is only partially
inserted.
