on the sensor. This includes both the incoming and outgoing sections of

the sensor.

3. Insert the sensor’s support arm into the mounting block of the mounting

bracket kit. Make sure the sensor points in the direction of the arrows that

appear after the word SENSOR on top of the bracket (see FIGURE 4-2).

Do not attempt to rotate the instrument using the sensor

heads, or you may damage the sensors; use the mounting

rod only.
