Maintaining the Recorder
Whether you decide to redeploy the recorder or place it in dry storage, follow
these maintenance steps.
1.
Remove and clean the O-rings. If a tool is required, use only plastic tools to
avoid damaging the smooth surface of the top cap where the O-ring sits.
2.
Inspect the O-rings for signs of wear; replace worn or damaged O-rings.
3.
Clean the top cap exterior, especially the O-ring area.
4.
Clean the inside of the cylindrical housing especially where the O-rings
make contact.
5.
Discard the desiccant pack. It is not reusable and must be replaced before
every deployment.
6.
Inspect the entire unit for damage to the housing, attachment points, or
hydrophone.
7.
Verify that the hydrophone is still tightly secured to the top cap. The bottom
of the hydrophone connector should make contact with the surface of the
top cap.
WARNING
: The hydrophone is a delicate instrument. Do not attempt to remove the
hydrophone from the top cap. Do not drop, shake, or apply force or pressure to the
hydrophone. Never use it as a handle or pick up the recorder or top cap by the
hydrophone. Removing or mishandling the hydrophone will void your warranty.
