Front and Rear Parking Sensor System

2 or 4 Front and 4 Rear In-Bumper Sensors

With Wired LED Display and Built-in Beeper

2 or 4 Front and 4 Rear In-Bumper Sensors

For Cars, Mini-VANs, 4X4s, SUVs, and Small Trucks

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.

How the System Works

The Parking Sensor System determines obstacle distance by measuring the time needed for the ultrasonic wave emitted by a sensor to reach an obstacle and for the sensor to receive the ultrasonic wave reflected from the obstacle. Given the speed of the ultrasonic wave, the system can then calculate and display the distance between the sensor and the obstacle.

To provide good coverage for both front and rear end of vehicle, the system comes with 6 or 8 sensors (2 or 4 front and 4 rear sensors). ♦ To have the look of factory installed system, the 6 or 8 sensors are in-bumper type (to be installed in the front and rear bumpers by drilling holes through the bumpers). ♦ Controlled by +12V from the back up light, the rear sensors are activated when the vehicle is put in reverse. ♦ 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). Seven (7) LED Lights (Green/Yellow/Red) on each side of the distance display indicate both orientation of obstacles and Safe/Warning/Stop zone. The audible alert (beeper) is built in the display with On/Off switch. ♦ For Beeper Only System (F2R4B ,F4R4B), it comes with a beeper (audible alert) only for easy installation without cluttering the dash. ♦ The system beeps faster as vehicle gets closer to an obstacle and sounds continuously when vehicle is within 1 ft or 0.3m from an obstacle.

Note: the front sensors may continue to work for 20 more seconds after foot brake is released.

Tools Needed

Φ21mm drill bit (include), drill, tape measure, chalk or marker, wire stripper, vinyl electrical tape, cable/wire ties, voltage meter, screw driver set, pliers. Note: Use a bi-metal 22mm drill bit (not included) if drilling through metal bumpers. For metal bumpers, holes drilled need to be slightly larger than diameter of sensors.

Installation and Wiring

IMPORTANT: (a) Read this manual thoroughly before proceeding to installation. You can also have the system installed by a professional installer such as your local auto mechanic/auto electrician/car stereo store. (b) Turn off the engine and ACC during installation. (c) Double check that all wiring is correct before powering on the system. (d) During installation, avoid flatting, perforating, cutting, and extending the wires of sensors to reduce unnecessary signal loss. (e) Never pull the sensor cables too hard or sensors may not work properly or at all.

1. Installing the Control Box

a) Find a flat and clean surface for the control box inside the vehicle near driver's side taillight

assembly but away from it for least 1 ft. As the control box is not water-proof type, you need to mount the control box to a location that is protected from water. Keep it away from areas of high heat, high humidity, direct sunlight, and electromagnetic devices.

b) Place the control box in place temporarily without securing it to the vehicle as you may need

to adjust the location of the control box while wiring. Note: After the system is working properly, use the double-sided self-adhesive pad (included) to secure it to the vehicle.

c) Insert the 4-pin plug of the power cable for the control box into its 4-pin socket labeled

"PWR" on the front side of the control box. See Fig. 4 (LED System) or Fig.5 (Beeper Only System).

Important Notes for Installing the Control Box:

Don't mount the control box near or under the dash or in the cab of a truck. The control box is designed to be mounted near the rear end of a vehicle (near taillight assembly) to avoid interferences from the engine which may cause false alert such as continuous beeping and 0.0 display (LED System only).

If Installing the System to a Truck, as the control box is not water-proof type, you may need to first mount the control box in a small water-proof metal or plastic box (not included with the system), then fix it to a location near the rear end of the truck.
