Thank you for purchasing the EW OBU. This manual shows how to operate the device smoothly and
correctly. Please read this manual carefully before using this product.
Intended usage
The On-Board Unit (OBU) is intended to be used for electronic toll collection and other telematic services
and may be used only for these purposes, unless explicitly stated otherwise. Any other use will be
considered to be a prohibited misuse and may result in any claims being denied.
The EW OBU may not be opened or manipulated in any way other than those stated in this
manual and in the instructions from Eurowag. Only the original Eurowag charging cable and
accessories should be used.
Keep the EW OBU within a temperature range of -20 °C to 85 °C, away from fire, high humidity
or anything which could damage the device. Extreme temperatures can cause deformation of
the EW OBU and decrease the capacity and durability of the battery.
Switch the EW OBU into offline mode (see Offline mode and return of EW OBU) in places where
the use of electronic devices is prohibited.
Handling of the EW OBU while driving is not permitted! The buttons are locked to prevent any
operation during vehicle movement (see EW OBU Locked mode).
As an electronic device, any EW OBU device not in use should not be discarded as trash but
should be returned to Eurowag along with accessories and cables.
Do not remove the batteries from the EW OBU. Return the complete EW OBU to the address
of our partner UPS SCS. The partner address can be found at the end of the section Offline
mode and return of EW OBU. Please contact Eurowag Customer Care for further information.

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 intheir resting position, must not obstruct the EW OBU. The EW OBU must not obstruct
the driver’s view in any direction.
