6) It is important not to drill the hole larger than the measurement indicated.
MUST use the hole saw provided.
6) Route the sensor wires through the bumper to a suitable location in the
vehicle trunk or rear hatch. Connect the main control unit RED wire to a
positive charge wire of the vehicle back-up light. Connect the main control
unit BLACK wire to a stable ground.
7) After routing and attaching the cables, use an offal (small block of wood, etc) to
press the sensors into place. NEVER push the sensor heads (center portion) to
push into the bumper.
5. Detecting Range
Normal Detecting Range
The sensors’ detection range is as following. They can detect up to 8-feet.
Programming the Control Box with a Spare Tire or Bicycle in Back of Vehicle
In case the vehicle carrying a spare tire or a bicycle, the control unit can be pre-
adjusted to indicate the alternative STOP position. There are five adjustment levels
(0.5 feet for each level): 0.0(level 0 as Default) =>1.0(level 1, -0.5 feet)
=>2.0(level 2, -1 feet) =>3.0(level 3, -1.5 feet) =>4.0(level 4, -2 feet) =>5.0(level
5, OFF) => 0.0(level 0 as Default). The button is removable and the setting can be
kept. Make sure to TEST before the usage (using at least 3X3-feet size cardboard) in
order to avoid accidents.
Important!
Do not use the negative charge wire of the vehicle back-up light for ground. Some
vehicles have a “check bulb” feature that makes that wire not a true ground.
The system may not detect a small and round pole (such as a fire hydrant or light
pole, etc).
When the vehicle approaches a rising slope, the slope may not be detected, as
most of the signal will be reflected up and not back at the vehicle.
