Note for 6-Sensor Parking System
If you purchased a 6-sensor system (F2R4B or F2R4L), it is
actually our 8-sensor system shipped with two(2) front sensors.
The two front sensors shipped with the 6-sensor system are
labeled as 'E' and 'H'. Depending on your specific vehicle or
application, they can be plugged into either the control box's
ports 'E' and 'H' or ports 'F' and 'G' corresponding to the same
sensor locations on the front bumper of vehicle as shown in
Fig. 2 in the User's Manual.
Install the two front sensors to bumper locations 'E' and 'H' for
better corner coverage of the front bumper, or install to bumper
locations 'F' and 'G' for a balanced front bumper coverage as
shown in Fig.2 in the User's Manual.
Two additional front sensors can be ordered at our online store
and added to the 6-sensor system to make it a 8-sensor
system as the control box is 8-sensor ready.

- Page 4 ♦ Controlled by +12V from the brake light, the front sensors are activated when parking/driving forward with foot-braking. ♦ For LED System (F2R4L, F4R4L), it comes with a wired LED display which shows the distance of an obstacle in front or rear of the vehicle (displayed as 0.0 if obstacle is within 1 ft or 0.3m).
- Page 5 Note: Some lights (turn signal/brake/reverse/stop lights) may emit interferences that can affect the signals the control box receives therefore cause the system to give false alert. After installation, if you experience false alert caused by turn signal light, or brake/reverse/stop lights, try to put the control box as far as possible away (at least 1 ft) from the taillight assembly (or turn signal/brake/reverse/stop lights).

- Page 10 Warnings ● Detection Range of the System The parking sensor system detects obstacle by emitting ultrasonic wave and receiving reflected ultrasonic wave from an obstacle. Different materials have different reflection and absorption of the ultrasonic wave, and the actual detection distance varies depending on what materials an obstacle is composed of.
