clean if needed. Do not use a dented cone. Incorrect readings may result.
Inspect the cone hanger to verify that the hanger is not bent or distorted. Check by
laying the hanger flat on a table. Make minor adjustments as needed to ensure that
the hanger lays flat. Carefully install the cone on the transducer mount pins on the
cone hanger as shown below. Insert the ends of the cone hanger into the
protruding cone hanger mount post holes, making sure they are properly seated.

3. If a transformer is to be used, plug it into the jack located at the lower left rear of
the unit. Then plug the transformer into a wall socket.
Note: There are transformers available for all plug and voltage configurations,
which can be ordered separately.
4. Allow sufficient time for the UW-7 to fully adjust to room
temperature. If the unit is not at room temperature, the transducer will be slowly
warming or cooling and will cause the readings to shift.
5. Obtain a bottle of the distilled and degassed water prepared following the
procedures discussed earlier in this chapter. Be sure that the water is at room
temperature before continuing with set up.
6. Open the bottle of degassed water. When the vacuum seal is broken you should be
able to hear it. If you do not hear or feel the seal being broken, discard the water.
