Symptom
Possible Causes and Solution
No Distance Readings
Ensure you have power to the system as
needed.
Double check all Sensor, Camera and power
connections.
No Sound
Ensure the volume is turned up to a desired
level and not muted.
Improper Readings.
Make sure the Sensors are free from obstruc-
tion and nothing is blocking the signal.
Make sure the Sensors are properly aligned. If
the Sensors are mounted over 32 inches from
the ground, they may need to be aimed slight-
ly downward, but no more than 5 degrees.
Make sure the Sensor surfaces are clean and
clear of debris.
Make sure there are no sources of interfer-
ence, such as those from ultrasonic or electro-
magnetic fields.
The Sensor operates at 40 kHz. Noise in or
around that frequency may create interfer-
ence.
No Picture or Sound
Does the Monitor Power LED light up? If not, the
Monitor does not have power. This could be due to
using an improper power supply or a loose con-
nection. If it is RED, the Monitor has power but is
not turned on. GREEN indicates the Monitor is on.
If the unit is not working properly, please review the following suggestions, prior to
contacting Mobile Awareness:
1) Double check all connections, including all 4-pin Camera and extension cable
connections, as well as the 22 pin wiring harness.
2) Check your power and ground connections. If utilizing a back-up Camera, be sure
the Brown Trigger Wire (from the 22-pin wiring harness) is connected to the vehi-
cle reversing light power source.
