Safety
IT security
We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any inadvertent
changes to the device settings.
IT security measures in line with operators' security standards and designed to provide additional
protection for the device and device data transfer must be implemented by the operators themselves.
