The software supplied with the equipment enables you to check the battery charge (see above, page
15). When the battery charge is too low and does not allow the equipment to be used for
measuring, the LED will flash twice in succession at regular intervals.
A warning is displayed on the radar status screen when the battery voltage reaches 5.9 V. It is no
longer possible to switch to measurement mode below 5.5 V and the radar stops completely at 5 V.
b. Operating temperature
The system can operate in a temperature range from – 20°C to + 50°C. The battery capacity is
however reduced at extreme temperatures.
c. Sealing
The system is rainproof. The housing is protected by a door fitted with a gasket. This can only be
opened in a dry place by an approved technician or your distributor. To guarantee the seal, ensure
that the housing locking clips are locked and that the protective cap is fitted on the connector while
the equipment is in operation.
d. Detection direction
By default, the radar measures the speed of vehicles moving towards it. It is possible to measure vehicles
moving away from it and, in certain conditions, bidirectional traffic (see above, page 18).
e. Accuracy of the measurements
The accuracy of speed measurement in laboratory conditions is greater than 98 %. The counting accuracy
is approximately 98 %. The vehicle classification accuracy is approximately 90 %. These values are
achieved in optimal installation conditions (see below), with a single lane of traffic.
The radar can measure speeds between 10 and 255 km/h.
REMINDER
• To avoid any polarity issues, do not use other wiring, power or charger than those supplied
with the traffic counter.
• A defective battery may emit some gas potentially explosive.
o Charge you battery in an open environment:
▪ If your radar has an external connector on the housing: remove the safety screws
and open the top while charging the batteries;
▪ If your radar hasn’t any external connector on the housing: remove the safety
screws. You can then open the top and connect the charger to the battery pack.
Let the top open while charging the batteries;
▪ In both cases, do not touch the antenna: it is an Electrostatic-Sensitive Device;
▪ Once your batteries are loaded, close the top carefully:
• do not catch the wiring;
• screw slightly the safety screws.
o Check regularly your batteries: inflated battery, white deposit on the battery’s
terminals, acid or gel leak, warm battery during the charging process are signs which
must alert the user on a battery potential default. If one of these phenomena occurs,
replace your batteries.
o Replace your batteries every 3 years.
