Disposal
Electronic devices are recyclables and must not be disposed of in the household
waste!
Please dispose of the product, when it is no longer of use, according to the current
statutory requirements.
Remove the batteries if there are batteries inserted and dispose of them separately
from the product.
Disposal of batteries and rechargeable batteries
As the end user, you are required by law (Battery Regulation) to return used batteries. Do not
dispose of used batteries in the household waste!
Batteries/rechargeable batteries containing hazardous substances are labelled
with the symbol shown to indicate that disposal in household waste is forbidden.
The symbols of the critical heavy metals are: Cd=cadmium, Hg=mercury, Pb=lead
(marking can be seen on the battery/rechargeable battery, e.g., underneath the
refuse bin symbol shown on the left).
You can return your used batteries/rechargeable batteries free of charge at the official col-
lection points of your community, in our stores, or at places where batteries or rechargeable
batteries are sold!
You thereby fulfil your statutory obligations and contribute to the protection of the environment.

product adheres to the fundamental requirements and the other relevant regulations of Direc-
tive 1999/5/EC.

Replacing the sensor batteries
Keep batteries out of the reach of children.
Do not leave batteries lying around in the open; there is a risk of them being
swallowed by children or domestic animals. If they are swallowed, consult a
doctor immediately.
Leaking or damaged batteries can lead to caustic burning of the skin. There-
fore, use suitable protective gloves.
Batteries must not be short-circuited, opened or thrown into a fire. There is a
risk of explosion!
Do not recharge normal, non-rechargeable batteries, risk of explosion!
Please observe the correct polarity (plus/+ and minus/-) when inserting the
battery.
Remove the batteries if you do not use the sensors for a longer period.
(see section “Sensor battery replacement” in the original instructions in English)
(1) Push back the dust proof cover and loosen the lock nut on the sensor.
(2) Unscrew the sensor from the valve.
(3) Remove the special washer from the sensor.
(4) Unscrew the sensor cap using the sensor tool supplied.
(5) Replace the sensor battery with a new 3V lithium coin cell battery (CR1632). Please pay
attention to the correct polarity as shown in the picture.
(6) Reinstall the sensor by following the steps described in the section “Sensor installation”.
Do not mix up the sensor caps when replacing the battery; this may result in incor-
rect mapping of the individual tyre positions.
The battery life is approximately 2 years. However, this depends very much on the
mileage travelled. If a sensor battery is flat, the battery warning occurs via the dis-
play unit. In this case, replace the battery as described above.
Selecting the pressure unit
(see section “Pressure unit selection” in the original instructions in English)
(1) Press the middle button on the display unit for three seconds, until an audio signal sounds.
(2) Press one of the outside buttons to select the unit for the tyre pressure display (bar or psi).
(3) Press the middle button on the display unit for three seconds, until two audio signals sound.
Sensor coding
The sensors have already been coded to the system at the factory. However, a sensor must be
recoded after it has been replaced.
(see section “Sensor programming” in the original instructions in English)
(1) Press the middle button on the display unit five times. A signal tone is emitted.
(2) Press one of the outside buttons until the sensor position to be programmed flashes.
(3) Screw the sensor to be recoded onto the corresponding tyre valve as described in the sec-
tion “Sensor installation”.
(4) The tyre pressure of the corresponding tyre is shown flashing on the display unit.
(5) Press the middle button on the display unit once and use the right button to select the
next sensor to be programmed (if desired). Proceed as described above to program all
additional sensors.
(6) Press the middle button on the display unit for three seconds, until two audio signals sound.
Maintenance and care
Regularly check the technical safety of the tyre monitoring system, e.g. for leaks at the sensors.
If it can be assumed that safe operation is no longer possible, the product must be turned off
and precautions are to be taken to ensure that it is not used unintentionally.
Safe operation can no longer be assumed if:
• the display unit or the sensors show visible damage
• the system no longer functions or
• following considerable mechanical stresses.
Apart from replacing the batteries in the sensors, the system does not require any maintenance
and should never be disassembled.
Please use a soft and clean cloth for cleaning the display unit.
Do not use any chemical or abrasive cleansers. This may result in discolouration of the plastics
of the enclosure or damage to the surfaces.
