| WHAT
IS ECHOVISION?
-A blind spot
obstacle detection system. |
|
HOW DOES ECHOVISION
WORK?
-It sends out ultrasonic
pulses and listens for their return. |
|
DO I HAVE TO
TURN THE SYSTEM ON?
-No, it is
turned on automatically when you put the vehicle in reverse. |
| WHY
DOES THE SYSTEM BEEP EVERY TIME I PUT THE VEHICLE IN REVERSE?
-The system gives a short series of high and low tone
bursts every time it is turned
on as a test of the audible warning components. |
| WHAT
DOES THE "FAULT" AND "READY" ON THE DISPLAY MEAN?
-"Fault" means the system has a malfunction.
-"Ready" means the system is operating. |
| WHAT
WILL THE SYSTEM PICK UP?
-Obstacles
within approximately 10 feet of the rear of the vehicle. |
| WHAT
HAPPENS WHEN AN OBSTACLE IS DETECTED?
-If
the obstacle is within 10 feet but further, than 4 feet from the rear of
the vehicle an interrupted-tone alarm is sounded. The pulse rate of the this
warning increases as the distance between the sensors and the detected
obstacle
decreases. When the obstacle is within 3 feet an alternating
high/low tone
is sounded. |
| WHAT
WON'T THE SYSTEM PICK UP?
-Anything
outside of the 10 foot range.
-An object that cannot reflect sound waves back
to the receiver, e.g. a smooth flat
surface that deflects the ultrasonic waves
to the side. |
| CAN
WE GET FALSE ALARMS?
-Yes, if
you are backing down an incline such that the sensors are angled towards
the
ground you can get an alarm from the ground return.
-Also, ground level irregularities
such as potholes and curbs can reflect the
ultrasonic pulses and cause an
alarm. |
