8.6 Trouble shooting
No „188“ value displayed after power on
Prove connection between battery clamps and control panel connector for
intermittent cable wires. Are the connector/socket contacts deformed or cor-
roded? Check the main fuse in the battery box. Control the battery voltage –
are 11,3 Volt present at the connectors when connecting the battery?
If you are not successful, you have to send us the system back for repair.
„188” does not disappear after power on
Send us the system back for repair.
„188“ flashes after power on continuously
Reason is probably an old or defective battery, which lost its energy storing capacity. Retry it
with a new battery. If you do not succeed contact us.
No speed value appears during vehicle detection
Has the viasis „free sight“ to the vehicles? Is the viasis straightened correctly (chapter 5
foll.)?
Are other high frequency wave radiating installations like high voltage lines, radar or radio
antennas in the near surrounding?
Is the minimal or maximal displayed speed set correctly (see chapter 6.3.4.2)?
Is the Led display deactivated in the actual valid parameter set (see chapter 6.3.2.1)?
Is the measurement time limited in the time schedule of the currently valid parameter set (see
also chapters 6.3.2 foll.).
Has the sensitivity of the radar been reduced (see chapter 6.3.7)?
If you don’t succeed contact our technical support first.
Car speedometer and display value are not equal
Car speedometers are not calibrated and show a remarkably higher speed than the real physi-
cal speed of a vehicle. To check the accuracy of the measured speed no car speedometer can
be used, except it was calibrated by the manufacturer (what is not done for serial cars).
An exact check of the accuracy must be made with a calibrated reference system (with radar,
laser, infrared or other optical methods) or a police car with calibrated speedometer.
If you have anyhow the impression that the displayed speed value is too low read chapter
5.1, 5.2 and 7.2 first.
If you don’t succeed contact our technical support first.
