2 BATTERY CHARGING
RSE622 is powered by a rechargeable Li-Ion battery. A USB charger and cable are included for
charging the battery from a standard socket. The battery comes partially charged. Charge the battery
for at least 3 hours before the first use of the RSE622.
2.1 OBU Reading Zones
The longest reading range is achieved when OBU and Transceiver is pointing directly toward each
other. Any angle on RSE622 or OBU is reducing the range.
The drawing below shows the typical OBU reading zones for passenger cars and trucks. The
different coloured reading zones represent the RSE622 height above ground.
The reading zones diagram shows that the reading zone is smaller for light vehicles with angled
windscreen at all height for the DSRC transceiver. When the RSE622 is held at
“normal head height
of a person (1,75m) is approximately x=3 by y=3 meters wide for a light vehicle (angled windscreen).
The reading zone for a large vehicle with an almost vertical windscreen is x=4 by y=6 meters
