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 8
sensors (4 front and 4 rear sensors). ♦To have the look of factory installed system, the 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 forward parking/driving with braking. ♦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 0.3m or 1 foot). Seven (7) LED Lights (3 Blue/2 Yellow/2 Red) on each side
of the distance display show both orientation of obstacles (left and/or right) and
Safe/Warning/Stop zone indicated by blue/yellow/red LED lights. ♦One audible alert (beeper) is
built in the display with volume On/Off switch, and sounds only when the front sensors are
working (when forward parking) ♦And a separate rear beeper is to be mounted near the rear
end of the vehicle and gives alert only when the rear sensors are working (when reversing). ♦
The system beeps faster as vehicle gets closer to obstacle and sounds continuously when
vehicle is within 0.4m (1.3ft) from an obstacle.
Note:
♦The front sensors will continue to work for 10 more seconds after brake is released.
♦The system may beep once under the following conditions to let the driver know the system is activated and ready or
deactivated: (1) When vehicle is started or ACC is turned on or off (2) When vehicle is put in Reverse gear.
Tools Needed
Φ22.3mm (7/8") drill bit (include), drill, tape measure, chalk or marker, wire stripper, vinyl
electrical tape, cable/wire ties, voltage meter or test light, screw driver set, pliers.
Note: Use a bi-metal 22.3mm (7/8”) drill bit (not included) if drilling through metal bumpers.
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.
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.
Note: To avoid possible interferences from the taillight assembly, keep the control box away
from the taillight assembly for at least 12”. 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
toadjustthelocationofthecontrolboxwhilewiring.
Note: After completing all wiring, use the double-sided self-adhesive pad (included) to
secure it to the vehicle.
c) Insert the 5-pin plug of the power cable for the control box into its 5-pin socket labeled
"PWR" on the front side of the control box. See Fig. 4 for details.

Warnings
●To avoid collision with obstacle because of the inertia of vehicle while backing up/parking,
keep your vehicle speed at about 3 miles per hour and stop the vehicle immediately once
you hear the continuous beeping. This is because even if you have applied brake, your
vehicle will still go for some distance (inertia) before it comes to a complete stop.
●Because the parking system detects obstacle by emitting ultrasonic wave and receiving
reflected ultrasonic wave from obstacle, the system may fail to give both visual and audible
alert if an obstacle has smooth ball-shaped or sloped surfaces as such surfaces may not
reflect ultrasonic wave back to the sensors. Drivers in these situations should pay more
attention while parking their vehicles.
●In heavy rain or snow, the system may give alert as falling rain or snow may be detected as
obstacles. Keep surface of sensors clean of snow, mud, dirt, and other debris.
