Final Storage or Shipping Preparation
Store the RiverPro/RioPro in the original shipping crate whenever possible.
1. Remove the battery from the boat and ensure the interior of the boat is dry.
2. Disconnect the I/O cable and remove the transducer from the boat. Place the dummy plug on the
transducer cable connector.
3. Dissemble the boat (if required) and place it into its own shipping container.
4. Place the transducer in the foam cutouts in the bottom of the shipping case. The RiverPro trans-
ducer will fit into the shipping case with the mounting plate installed. If stored this way, remove
the extra foam material that has already been pre-cut from the instrument cavity. This will create
a slot in the foam allowing the mounting plate to slide into the case.
Always dry the RiverPro/RioPro before placing it in the storage case to avoid fungus or mold
growth. Do not store the RiverRay in wet or damp locations.
The dummy plug should be installed any time the I/O cable is removed. Use the dummy plug
when the RiverRay transducer is in storage or is being handled.
Do not leave the batteries inside the RiverPro/RioPro boat for extended periods. The
batteries may leak, causing damage to the boat. Store the batteries in a cool, dry location (0
to 21 degrees C).
Calibrating the Compass
RiverPro/RioPro compass calibration corrects for distortions in the earth’s magnetic fields caused by per-
manent magnets or ferromagnetic materials near the RiverPro/RioPro. These magnetic field distortions,
if left uncorrected, will create errors in the heading data from the RiverPro/RioPro. A compass calibration
should be conducted at each measurement location, and whenever the mounting fixture, boat, or ancillary
equipment such as batteries or radios are changed or rearranged. Be aware of the following items:
•
Compass calibration is especially important when using the RiverPro/RioPro on a manned boat
as they often have significant magnetic field distortions from the hull, engine(s), and ancillary
equipment. Accurate calibration may not be possible in extreme cases.
•
If the mounting fixture or frame has some magnetic field or magnetic permeability, calibrate the
RiverPro/RioPro inside the fixture. Depending on the strength and complexity of the fixture’s
field, the calibration procedure may be able to correct it.
•
Ferromagnetic structures such as bridges or sheet piling in the measurement location may inter-
fere with proper compass operation. The compass calibration procedure can NOT correct for
heading errors due to these types of structures.
For detailed instructions on calibrating the compass, see the WinRiver II User’s Guide.
