• Adapter set for motorcycles. In this case the
TARGET LRC 100-M version must be ordered. This set is
completely waterproof and weather resistant and is
also provided with a special optical indicator that is
visible for motorcyclists in all circumstances.
How does the TARGET LRC 100 work in
combination with external transponders?
The separately available external transponders for the
TARGET LRC 100 make it possible for you to operate
doors, gates and lighting automatically from a distance.
This transponder, a separate module that can be mounted
inconspicuously on the wall of your garage, for example,
looks for automatic contact with the transponder on your
vehicle at the moment that it comes within range. As
soon as the transponder concerned is registered by the
TARGET LRC 100, this responds to the signal and the con-
nected system (garage door, lighting or gate) is activated.
The distance that can be bridged between the two
transponders is approximately 50 metres. Comprehensive
instructions with regard to installation and use will be
found in the packaging of the external transponders.

How does a laser gun work?
A laser gun uses infra-red (invisible) laser light that func-
tions best when it is aimed at optimum
reflecting components such as the licence plate or the
headlamps. The computer, that forms an integral part of
the laser gun, calculates the time that the emitted laser
beam takes before it is returned and subsequently
displays the speed of the vehicle at which it is aimed.
On average, a laser gun emits approximately 100 separate
pulses in the 0.3 second that is necessary in order to
determine the speed of a vehicle. In contrast with radar
measurements, a laser gun can pick out a particular
vehicle from a group with considerable accuracy (see
figure 1). At a distance of 300 metres the width of the
beam is approximately 1 metre. A radar beam is many
times wider (see figure 2).
How does a laser detector work?
Laser detectors that can be mounted behind the
windscreen provide little or no protection against laser
guns because in most cases, they only detect the laser
beam when it is aimed at the vehicle. If a laser detector
nevertheless gives an alarm, it will be too late to apply
the brakes because the laser gun will already have
established the speed of the vehicle.
Aan what does the TARGET LRC 100 do
in this case?
The Target LRC 100 is an active laser detector. The recei-
ver part (the infra-red photo diode), is so adjusted that
no false alarms can occur. However, as soon as a laser gun
is aimed at your vehicle the system comes into operation.
In that case the TARGET LRC 100 emits a signal with a
duration of 7 seconds that will be picked up by the laser
gun. At the same time you will be warned by the
light/sound signals on the display in the vehicle. During
this 7 second period, the laser gun cannot establish the
speed of your vehicle and you have sufficient time in
which to check, and if necessary reduce your speed. After
a transmission session of 7 seconds the system functions
only as detector for the next 60 seconds (you will then
be warned when your vehicle is being shot with a laser
gun but the system will not transmit a
figure 1

5
corresponding signal). Thereafter, the system
automatically returns to standby. The only reason that the
TARGET LRC 100 discontinues the laser transmission after
7 seconds is to give police the opportunity to determine
the speed of your vehicle at a moment that is best
for you.
Laser guns are provided with special narrow-band filters
that prevent light sources originating from LEDs (Light
Emitting Diodes), headlamps, sunlight reflectors, etc.,
from disturbing the measurement. The LRC 100 accordin-
gly makes use of an indium gallium arsenide laser diode.
This is exactly the same type of diode as that used in the
guns. The LRC 100 sends a powerful laser signal with the
wavelength that is normally used by laser guns to receive
reflected signals. The signal produced by the LRC 100
reaches the laser gun before it receives the reflected
signal. In this way the laser gun is prevented from
determining the speed of the vehicle concerned.
For many questions arising concerning laser guns
and the TARGET LRC 100 we refer you to the section
"The most frequently asked questions concerning the
TARGET LRC 100" on page 10-11.

Installation
Ensure optimum performance of the Target LRC 100.
In order to be certain that the system will function in
an optimum manner you must follow the instructions
given below.
Mounting the transponder
For preference, mount the transponder in the immediate
vicinity of the licence plate on the front of the vehicle.
This may also be in or behind the grille. Note that when
the transponder is mounted behind the grille the
necessary "window opening" must be larger the further
the transponder is behind the opening. For this refer
to the conversion table on page 8.
One transponder is sufficient for:
• Practically all private cars.
• All vehicles for which the distance between the licence
plate and one of the two headlamps is not more than
55 cm. (measured from the edge of the licence plate
to the inside edge of the headlamp.
Two transponders are necessary for:
• Situations in which measurements with a laser gun are
regularly made over a short distance (<100 metres).
NB. This situation does not occur very often in practice.
• All vehicles for which the distance between the licence
plate and one of the two headlamps is greater than 55
cm. When two transponders are fitted, it is recommen-
ded that the transponders be mounted with the licence
plate as the middle point, with a distance of 1/3 of
the width of the vehicle between them. The assembly
and wiring instructions for a second transponder are
included in the packaging of this transponder.
For the installation of the
TARGET LRC 100 proceed as follows:
1. Determine the number of transponders required and the
installation position (1 transponder on the front of the
vehicle is nearly always sufficient).
2. Mount the transponder with the aid of the mounting
brackets included in the package. Depending on the
situation, make use of the U or L sections (see figures 1
and 2).
3. Ensure the correct alignment of the transponder
(figure 6).

4. Feed the cable of the transponder through the engine
compartment. For this, make as much use as possible of
the existing cable guides. Do not pull the cable too
tightly and ensure that there are no sharp kinks in the
cable. Feed the cable through an existing grommet to
the interior of the vehicle. Make all connections as
shown in figure 4.
5. IMPORTANT! Connect the power supply cable (this is the
cable with the switch and the 3A fuse) to a switched
+12V wire (+15). This is the wire to which voltage is
applied when the vehicle ignition is switched on.
Connect the black (-) wire to a ground (chassis).
6. Mount the switch and the piezo buzzer under
the dashboard for preference. It is not essential to
connect the LED but it can be fitted in a visible position
on the dashboard if desired.

ligning the transponder
It is of great importance to correctly align the transpon-
der. This applies to both the vertical and the horizontal
positions (see figure 6).
Vertical: Upward / downward. Ensure that the vehicle is
level. For the adjustment of the vertical position use the
spirit level supplied. Hold this with one of the ends at
right angles to the lens of the transponder and screw the
bracket in position when the correct alignment has been
reached (see figure 1).
Horizontal: Left / right. The mounting brackets included
provide you with the possibility to aim the transponder
to the left or to the right. The transponder must be fixed
at right angles to the long axis of the vehicle.
To achieve vertical and/or horizontal alignment it may
be necessary to bend the fixing brackets used slightly to
obtain an optimum result.
TARGET LRC 100 conversion table for
the installation of the transponder

Testing for correct operation
After the TARGET LRC 100 has been installed in accordan-
ce with the instructions the system can be tested for
correct operation.
Switch the system on by switching on the vehicle’s
ignition. Switch the LRC 100 on with the aid of the
on/off switch.
Result: After several seconds the buzzer will give 2 short
bleeps and the LED (if connected) will light up at the
same time. The system is now ready for use.
Statutory provisions
Throughout the world, the emission of laser light is not
subject to statutory provisions and is thus permitted.
In the first place the TARGET LRC 100 was developed as
an active outside lighting and access control system
(garage door, gate, etc.) in which a greater degree of
safety for the driver of the vehicle was the central issue.
In order not to interfere with laser speed measurements
made by the police, you can decide to switch off the
system while driving on the public highway.
Safety
The TARGET LRC 100 is a so-called Class I laser. This laser
is safe for the eyes and because of its divergent beam
(widely fanned out) and a number of safety measures
built-in to the system, it is completely harmless.
The LRC 100 only transmits a signal when the system is
activated by the external transponders or a laser gun.
Use the LRC 100 exclusively for applications in
road vehicles and vessels. If you wish to examine the
transponder for damage, we recommend that you take
the precaution of first switching off the vehicle ignition.
Important information for every user
•Check the lens of the transponder regularly for conta-
mination. For preference, do this every time you make
a stop for fuel. Dust and salt have only a limited
adverse influence on the proper functioning of the
system. Anything that completely covers the lens,
such as leaves or insects, must be removed.
• Also check the housing and the lens of the transponder
regularly for damage.
Switch off the system and contact your dealer if the
lens appears to be damaged.
• Have the adjustment of the transponder checked
periodically (for example 1 x per year) by your dealer.

The most frequently asked questions
concerning the TARGET LRC 100
1. Can the TARGET LRC 100 be used in place of a radar
detector?
No, the TARGET LRC 100 only receives signals from laser
guns and thus offers no protection against speed traps
that function with the aid of radar equipment. In addition
to the TARGET LRC 100 you need a good radar detector.
2. Does the TARGET LRC 100 also generate a false alarm,
as so often happens with some radar detectors?
No, a quieter travelling companion than the
TARGET LRC 100 does not exist. Because of the active
filters with which the system is provided, there is never
any question of a false alarm. All non-infra-red light
sources are accurately filtered out. The system reacts
only to infra-red light sources with a wavelength of
904 nanometres. Your TARGET LRC 100 gives an alarm
when you are within range of one of the transponders
(garage door, etc.) or when your speed is being
measured with a laser gun.
3. Is the TARGET LRC 100 effective against all
laser guns?
Yes, every laser gun, irrespective of make and type,
operating on 904 manometers, will be recognized as
such and will be neutralized by the TARGET LRC 100.
4. Does the TARGET LRC 100, separately or in combination
with a good radar detector, offer protection against all
speed traps?
No, it cannot offer protection against inconspicuous
surveillance vehicles that follow you and which make use
of a calibrated speedometer to establish your speed.
Neither is the system in a position to detect those
systems that function with the aid of a loop arrange-
ment embedded in the road surface (think about
combined red traffic lights and speed cameras, etc.).
5. Does an ordinary laser detector offer no protection
against speed traps using a laser gun?
No, an ordinary laser detector, such as is often present
in many radar detectors, is absolutely not effective.
At the moment that such a detector is activated, your
speed has already been recorded. Actually, you will only
be warned for the payment of a fine that arrives on your
doormat several weeks later.
6. Can the laser of the TARGET LRC 100 result in eye injury?
No, the TARGET LRC 100 is a class 1 laser system (safe
for the eyes) and is provided with a special lens by
means of which the laser beam fans out over a wide
angle (25° x 10°). The amount of energy that is
released in this way is very low and is accordingly
completely harmless.

7. Can I also use the TARGET LRC 100 to control systems /
equipment other than those referred to in the manual?
Yes, in principle any electrical system can be switched on
and off at a distance with the TARGET LRC 100. However,
before you consider doing this we recommend that you
contact the dealer from whom you purchased your
TARGET LRC 100.
8. Is the use of the TARGET LRC 100 as an active laser
detector also permitted in foreign countries?
In the way that it works, the TARGET LRC 100 is actually
identical to the infra-red remote control you use for
controlling audio and video equipment. As a remote
control for doors, gates and lighting there is no
limitation anywhere in the world on the use of the
TARGET LRC 100. Interference with the functioning of
a laser gun is only a side effect of the Target LRC 100,
comparable with the disturbance caused by the adaptive
cruise control systems fitted by various vehicle manufac-
turers and which are based on laser technology.
9. What makes the Target LRC 100 so exceptional in
comparison with other active laser detectors?
The Target LRC 100 is the only system that can be used
as a fully-fledged remote control. All other products
are so-called laser jammers or laser shifters, which are
exclusively intended to prevent a laser measurement
being made. This type of interference with a laser
measurement can be seen as "obstruction of justice"
and can accordingly be regarded as an offence. For the
Target LRC 100 this is only a side effect comparable with
the adaptive cruise control of, for example, the Nissan
Primera, which is based on laser technology and in the
first instance is intended measure the distance to a
vehicle in front but which at the same time makes
a laser measurement impossible.
In addition, the Target LRC 100 by far the smallest and
the only laser detector in the world that makes use of
patented laser technology. The LRC 100 employs the
same laser diode as that used in most laser guns throug-
hout the world. All other active laser detectors make
use of infra-red LED technology and are accordingly less
reliable when compared with more advanced laser guns.
