Rear View Safety
10
Summary
This bulletin addresses three solutions to the issue of false alarms
with the RVS-128, RVS-129, RVS-130:
• Sensor's orientation.
• Large surface anomalies in the sensor field of view.
• Use of steel screws in conjunction with the environment, resulting in reflections to the sensors.
Issue
Occasionally, when the system is installed and tested, there are constant false alarms as the vehicle
is moving even where there are no other vehicles in the area.
Solutions
Here are three additional possible causes and their solutions.
Wrong orientation
Change orientation 180°. The sensor should be oriented with the flat bottom attached to the
vertical side of the vehicle, perpendicular to the ground. The large end of the sensor should be
directed toward the back of the vehicle.

Why incorrect orientation is a problem: The microwave signal is emitted out of the larger end of the
sensor. The sensor will sense objects coming toward it. So, if it is pointing in the wrong direction,
it may sense things that are stationary, such as trees, as moving toward it. This is especially seen
when the sensor is pointing toward the front of the vehicle (all stationary objects would be moving
toward the sensor and cause false alarms).
