Safety and Precautions
WR3 has been designed for easy and safe operation. The alcohol interlock is to be used only for
the purposes specified herein. To help ensure your safety, you must follow these precautions:
• In response to a retest request, carefully stop your vehicle at the side of the road. Complete a
successful breath test before you resume driving.
• Do not open the handset case. Doing so will void the warranty and potentially damage the
components within.
• Avoid exposing the handset to direct sunlight for extended periods of time.
• If liquid spills onto the handset, remove the excess with a cloth and allow the handset to dry
thoroughly. If there is substantial moisture damage, do not turn the handset on. Contact your
local service centre.
• Keep all radio frequency (RF) transmitting devices (such as cell phones) away from WR3 to
minimize interference.
• Do not attempt to tamper with or circumvent WR3. This is considered a program violation.
Maintenance
During field use, WR3 is susceptible to dirt and debris. Clean the handset with a damp cloth and
mild soap. Do not use abrasive cleaners or solvents.
Periodic service appointments are required. Consult your compliance guide for more
information.

What is an alcohol interlock?
An alcohol interlock is an in-car breath alcohol
screening instrument. It prevents a vehicle from
starting if it detects that a driver’s breath alcohol
concentration (BrAC) is over a preset limit. It is
designed to fit inside the vehicle, near the driver’s
seat, and connects directly to the vehicle’s ignition
system.
The interlock consists of a handset and relay
module. The relay module enables or disables the
ignition of the motor and stores the handset settings.
To help prevent other people from providing the
required breath samples, the interlock requests
additional breath samples at random intervals
during the trip.
How does it work?
WR3 uses the same alcohol sensing technology used by police in
roadside screening. A special alcohol-sensitive cell detects the amount
of alcohol in the breath. Breath alcohol is directly proportional to the
blood alcohol concentration (BAC).

User Fees
Drivers who are subject to an alcohol interlock program are
responsible for all installation and maintenance costs. Refer to your
compliance guide for a complete list of costs.
Installation
Installation centres are conveniently located, and the interlock is
installed while you wait. You receive full training on site, and
technicians help to ensure that everything operates properly.
The interlock is installed by a qualified installer in accordance with
national regulations. An unqualified installation may invalidate the
type approval of the vehicle.
Maintenance
You must visit the installation centre a short time after installation. You
must also visit at certain intervals for maintenance and data
download. Maintenance appointments typically take less than 20
minutes.
Refer to your compliance guide for the interval dates.

Handset Cable
The handset cable connects the handset to the interface module,
which is connected to the vehicle’s ignition. The handset should
remain connected at all times, but for instances in which the handset
needs to be removed, follow these steps:
To Disconnect
1. Make sure that the vehicle motor is off.
The handset cable consists of a connector, a
sleeve and a cord.
2. Release the connector from the interface mod-
ule plug by pulling back on the sleeve. This
disconnects the handset cable.
Warning! Do not pull on the handset cord or turn the connector. This could
damage the cable.
To Connect
1. With the vehicle motor off, locate the green
arrows on the handset cable connector and plug.
Note! If the vehicle’s motor is running, the interface
module plug flashes green and beeps every 15
seconds.
2. Line up the green arrows and gently push the
connector into the interface module plug. A
light click sounds when they properly connect.
3. A Wait message displays. WR3 may require
another breath test. Observe the message on
the display.

More information
Alcohol Influence on Testing
Drinking alcohol and eating foods containing alcohol will cause a
failed alcohol test.
Some other factors that may affect a test (because they may contain or
produce residual alcohol in the mouth) are medicines, drops,
smoking, using mouthwash or mouth spray.
Rinsing the mouth with water after using mouthwash or mouth spray
will remove the alcohol content in the mouth.
According to the previous information, do not eat, smoke or drink for
at least 10 minutes before taking a test.
Additionally do not spray any air fresheners, disinfectants, cologne or
perfume in the vehicle prior to a test, as these can also contain
alcohol.
Note! The above mentioned list of factors that may affect a test is not
exhaustive. There are additional items that may affect the results of a breath
test. Follow this guide carefully to avoid incorrect results.
Operating Temperature
The maximum ambient operational temperature is between -40°C and
+85°C.
Note! Depending on the ambient temperature, the handset takes a few
seconds to warm up (approximately 15 seconds at 20°C, approximately
1 minute at 0°C).
Battery Voltage
The voltage supplied to the relay module, which in turn powers the
handset, is supplied by the vehicle battery.
For the 12V Interlock system, the vehicle battery voltage can range
from 9V - 18V.

Using the Interlock
Starting the motor
1. The interlock turns on automatically
when you plug it in, and Wait dis-
plays as the unit warms up.
If the interlock is plugged in, but has
gone into sleep mode, turn the power on
again by pressing the right button.
Alternatively, you can move the key
between the On and Off positions.
Note: The ignition must be OFF before you can
continue.
2. The handset displays Ready for test
when it has finished warming up.
The warm-up time is longer in cold
temperatures.
Note: Do not store the mouthpiece to be used
in a cold area. This causes condensation in the
mouthpiece and increases the opportunity for
water to enter the handset.
3. Insert a clean mouthpiece. Using a
clean mouthpiece is good hygiene,
and it helps to ensure a usable
breath sample.
Note: Do not eat, drink or smoke for at least 15 minutes before the test. This
could contaminate the breath sample.
