3. Installation
The EW OBU cannot be used in vehicles with metalized windshields (heated windshield, infrared
reflective windshield, etc.). The windshield must be non metalized or contain areas without
metallization for the EW OBU to function.
Please consider different windshield characteristics (e.g. metalized or unmetallized areas),
depending on the kind of windshield in your vehicle. Check the windshield characteristic in the
documentation of your vehicle. Some windshield coatings might hinder communication
between the EW OBU and the GPS / GSM / or other system used for toll collection.
The driver is responsible for the proper installation of the EW OBU. The EW OBU should be
installed in the middle of the lower part of the inside of the windshield. Objects, including the
wipers in their resting position, must not obstruct the EW OBU. The EW OBU must not obstruct
the driver’s view in any direction.
A. Before mounting the EW OBU, the installation area – the lower part of the inside windshield in the
center – must be cleaned with the enclosed surface cleaner.
B. Remove the protective foil from the screen. Foil not removed can damage the EW OBU!
C. Remove the protective foil from the tape and stick the EW OBU to the cleaned area of the windshield
with the buttons on the right-hand side.
D.
Connect the EW OBU to the 12V cigarette lighter socket using the charging cable provided.
