The PTS400EX (DP) is a 4-sensor parking
system that can be used as a front or
rear ultrasonic distance monitoring device
(Dual Purpose). It electronically detects the
area in front or behind your vehicle while
driving/parking, and alerts you with audible
tones and/or optional visual display, if the
system detects an obstacle. If you have one
of the optional displays fitted with the digital
numbers the system will accurately show the
distance to the obstacle. With features like
self-test and the learning function, the
PTS400EX (DP) is ideal for cars with nudge
bars, tow bars, rear externally mounted spare
wheels or other protrusions.
The optional visual displays are suitable for
dashboard, interior mirror or rear roof
mounting. When the display is mounted on
the rear roof it can be easily viewed from the
interior mirror.
Parking systems help to provide assistance
when reversing and parking. Driving skills,
such as slowing down, use of mirrors etc, are
always essential.
1. This unit is for vehicles with 12/24V DC
only.
2. The system should be installed by a
professional auto technician.
3. Wiring harnesses should be routed away
from heat sources and other electrical
components.
4. It is strongly recommended to check the
position of the sensors before actually drilling
the holes.
5. Perform a system test after installation.
The parking system is designed as a driver
assistance device, and should not be used as a
substitute for safe parking practices. The area
into which the vehicle is manoeuvring must be
constantly monitored while parking.
The manufacturer and its distributors do not
guarantee or assume liability for collisions or
damages while parking your vehicle.

How does the system work with the buzzer (Front system)

How does the system work with buzzer (Rear system) Attention Sensor maintenance
False detection may occur in the following situations:
After installation, please fully test the
system before use.
Heavy rain, dirty or damaged sensors may
cause a false alarm occasionally.
Ensure that the self-test procedure is
complete and all sensors are functioning
before manoeuvring.
Do not wash the sensors with high
pressure or apply too much force.
Please wash the car with low-pressure
water.
If the sensors are covered with Ice please
melt with warm water.
Clean the sensors with a cloth or
low-pressure water when the sensors are
covered by mud or snow.

Sensor installation
Suggested sensor spacing is 45cm apart. On some
vehicles this is unachievable due to the number plate
location or bumper design. This will mean the distance
between the centre two sensors will be greater (see
illustration). The kit will still function, however the system’s
detection of narrow objects i.e. posts will be reduced.

Changing the sensor head angle.
Take the silicone ring out.
Make sure the degree marking is on top
of the sensor.
Insert the silicone
ring into the sensor
again.

Painting instructions
Disassemble the sensor.
Take the silicone ring out.
Key down the surface of the sensor with
either a scotch pad or 1500 sandpaper.
Reassemble the sensor head.
Mask off the area of the head you don't
want to get paint on.

Make sure the head is free
from dust/dirt before
painting.
Clean the surface of the sensor
thoroughly with a pre paint wipe,
do not touch the surface again
after cleaning.
The painting should be done in a clean
dust free room.
When the sensor is completely dry, put the
silicone ring back in.
It is generally easier to cover the sensor
with paint if you rotate the head while
spraying.
When you have finished leave the sensor in
a clean dust free room until it has fully
dried. Drying times vary depending on the
characteristics of the spray paint used.

Make sure the size of the hole
saw supplied in the kit matches
the diameter of the sensors
before drilling any holes.
If a gap is found between the bumper and the sensor head when using the 10 degree clip on
head, adjust the angle of the hole as shown below.
