Be careful

Devices in the boxes have to be activated and calibrated before using. You can do that only with the SPlace and Device Management Android apps.

The method of device positioning in the SPlace Web App should only be used with already calibrated devices. Devices which were never calibrated will not send any data until calibration is performed.

• Calibration should always be formed after the device is securely mounted on the road surface.

• Calibration should be repeated if a device is repositioned.
