G) Button for switching off/on sound alerts
The OBU provides sound alerts (for example, when you press a button) and sound warnings.
The button is used to turn off/on sound alerts; deactivation of sound warnings is not possible.
To turn the sound alerts off, press the button; the OBU will give a sound alert as a confirmation.
Use the same procedure to turn the sound alerts on.
• To remove the OBU from the holder, gently push the tab on the top of the holder toward the
windscreen and tilt the OBU out of the holder (opposite the arrow on Figure 4).
• To remove the OBU from the holder, lift the suction cups (preferably by pulling on the suction
cup protrusion) to release the holder. Do not use sharp objects that could damage the suction
cups.
•
Software and OBU data can be updated remotely. This will turn off all the indicators. In princi-
ple, the update does not last longer than one minute. Do not start driving until the main status
indicator (A) turns green.
Before driving
• Make sure the power cord is properly plugged into the cigarette lighter socket.
•
Check that the main status indicator (A) is green and the toll account indicator light (B) is
green (or yellow - see in the chapter Using the OBU).
•
Check the set number of axles of the vehicle (including trailers, semi-trailers, etc.) on the axle
number indicators as shown on Figure 8 in (D). If the number of axles does not match the cur-
rent configuration of your vehicle/vehicle combination, set the correct number of axles using
the buttons (E). Only those values that are acceptable to your vehicle can be set. The driver is
responsible for setting the correct number of axles.
Caution:
The number of axles must be set in a stationary vehicle. The OBU buttons are locked
while driving.
When driving
When driving, occasionally check:
• the indicator lights did not change to red - especially the main status indicators (A) and toll
account status indicators (B);
• the power cord plug is still properly plugged into the cigarette lighter socket.
If you come from abroad, where the OBU does not have to be connected to the power supply,
connect the OBU power cord to the cigarette lighter socket before entering the Czech Republic
(at least 30 km before the border crossing) to ensure proper OBU operation. After crossing the
border, perform the checks as described in the chapter Before driving.
