3. Securely mount the sensor.

4. Use a user-supplied bubble level or the 25619 bubble level to make certain

the antenna horn is aligned within 1° of vertical. The cap needs to be

removed when using the 25619. If the antenna is not vertical, a

trigonometric measurement error can occur with respect to the water. The

maximum range is reduced because of the off-axis return signal.

5. Orient the sensor such that one of its polarization markings is aligned

towards the wall or pier (see FIGURE 4-1 and TABLE 4-4).
