INTRODUCTION

Thankyou for purchasing the PDC340
Reverse Parking Sensor. This manual
details the installation and operation of
your product. Please read it carefully and
keep to hand for future reference. Ensure
that the product is working correctly before
attempting permanent installation.

The PDC340 is an automatic reversing alert
system. It gives a safety warning which tells
the driver the distance between the rear of
the vehicle and any object in its path.

The sensors transmit an ultrasonic signal
when the car is reversing. When the signal

senses an object, it will be reected and

received by the PDC340 control unit. These

reected signals are analysed by the control

unit microprocessor to detect whether the
obstacle is in your path and at what distance.
The receiver unit illustrates the distances
involved with a series of beeps and
illuminated LED’s letting the driver know how
far away the closest object is located.

Below are graphical representations of the
PDC340 detecting patterns:

INSTALLATION GUIDE

IMPORTANT! During the installation

your vehicle must be in neutral and the
ignition switched OFF. Disconnect the
battery following the vehicle manufacturers
instructions before commencing.

Wiring diagram:

Below is a wiring diagram for the PDC340
sensors and control unit showing the
necessary connections. Please follow all the
instructions before installing your reversing
sensors.

LOCATION OF THE SENSORS

IMPORTANT NOTE: • It is strongly

recommended that the sensors are fully
tested in the proposed positions prior
to drilling or performing any irreversible
alterations to your vehicle. Before

installation rst determine the nal position

for the sensors.

Locate a at area at the rear of the vehicle. •
Sensors should be tted between 55cm­70cm from the ground. If tted higher

than 70cm the sensors may not detect
low objects. If lower than 55cm the signal

may reect from the ground and produce a

false reading.

The sensors should be tted 90cm apart •

from each other (at the same height).
The sensors are intended to be installed at •
a slight angle (see Fig.4).

Drill holes of 20mm in diameter to •
accommodate the sensors (see Fig.5). If
you are in any doubt as to where you can
drill safely, seek advice from your vehicle
manufacturer.

WIRING THE SENSORS

Having chosen a location for the sensors, •
you must decide on a route for running the
wiring through your vehicle’s interior. Do
not allow any wires to hang dangerously.

LOCATION OF THE CONTROL UNIT

Locate the transmitter towards the rear of •
the vehicle (e.g. in boot), within reach of
the sensor and power wires.
Only once a suitable position is established •
and the system has been fully tested can
the control unit be permanently installed
using the screws provided.

CONNECTING THE WIRING TO THE
CONTROL UNIT (TRANSMITTER)

You need to connect the red and black •
transmitter power cables to your vehicles
reversing light wires.
The red power cable should be connected •
to the positive reversing light wire (this
is the wire that becomes live when you
select the reverse gear), using the snap-on
connector provided.
Connect the black power cable to the •
ground wire from the reversing light, again
using the snap-on connector provided.

LOCATING THE RECEIVER UNIT

This must be installed inside the vehicle •
(e.g. on the dashboard) where you can see
and hear it easily whilst manoeuvring.
Do not attach in a position that could •
interfere with the normal driving of the
vehicle.
Attach using the sticky pad supplied.•
This must be installed within reach of the •
chosen power supply.

CONNECTING THE POWER TO THE
RECEIVER UNIT

Connect the receiver unit to the power •
supply either by plugging in the cigarette
socket adapter or by hardwiring (seek
advice from your vehicles manufacturer).
You will need to reconnect the battery
following manufacturers instructions.

SYSTEM SETUP

Once you have installed the system and •
switched it on, you will need to press the
‘LEARN’ button. This is located on the
back of the receiver. This lets the receiver
unit sense the transmitter unit and set up a
frequency.
If the mutual frequency is found •
successfully, then the receiver unit will
beep twice.
If the frequency is not found then you will •
hear a long beep. If this happens, switch
the receiver unit off and on, then press
the ‘LEARN’ button again. If you still have
problems, check the system setup and that
all wires are connected properly, and that
the transmitter unit is switched on.

Fig.6

OPERATION

When you select reverse gear, you will hear
a beep. This indicates that the PDC340 is
working and has been activated (it does not
necessarily mean that there is something
behind you.)

As you begin to reverse and an object
comes within range, you will hear a beeping
sound from the main unit. The frequency
or pitch depends on the range of the object
being detected. If necessary, you can use
the switch on the side of the unit to increase
or decrease the volume.

The detective range is 0.4m to 1.5m. Its
resolution is 30mm. The accurate distance is
transmitted from the control unit (transmitter).
The LED display corresponds to the shortest
distance from the obstacle.

The table below shows the alarm speed
corresponding to the range of the object
detected.

WHEN THE BEEPING INCREASES
AND FINALLY BECOMES A
CONTINUOUS TONE AND ALL OF
THE LED’S ON THE MAIN UNIT ARE
FLASHING, YOU SHOULD STOP
IMMEDIATELY, EVEN IF THERE IS NO
OBVIOUS OBSTACLE BEHIND YOU.

Your PDC340 may work slightly differently to
what is shown in the table above depending
on circumstance and also on how your
sensors are positioned. You should practice
using your set up in a known area before
using it in earnest on a day to day basis.

With use, you will nd it a convenient and

useful aid to your reverse parking.

Fault Finding

FAULT DESCRIPTION POSSIBLE CAUSE/REMEDY

False or no response Steep slopes or thin bars. Bushes or other

foliage could absorb the signals. Electricity
wires nearby could interfere with the signal.
(See diagram below) Sensors covered with
snow, mud or ice etc.

Power light does not come on when reverse
gear has been chosen.

Check that the power wires are properly
connected to the reversing light power
wires. Check that the snap-on connectors
are providing a good contact.

Sensor always shows an object is FT (Red
LED) behind vehicle.

Check whether the sensors are located too
low, or the angle is pointing downwards and
therefore detecting the ground.

Power light (Green LED) is on, but the unit it
not detecting any obstacles

Check whether the sensors cable is
correctly plugged into the 2 pin socket of the
transmitter unit.

Unit does not show correct distances. Check that the sensors are properly

mounted. Adjust as necessary.
