Customers that want to modify the configuration can apply for specific agreement here. Once approved, all purchased units will have unique password assigned. Since a new label or remark must be placed on the unit when the original configuration is modified, this procedure is not recommended for occasional users.

Note on EC type-examination
Since EN 298 does not describe all functions of the QBK – implemented to manage all possible industrial scenarios – the operator is responsible for ensuring that parameters and functions are appropriate for the application.
Certification applies only for options and values allowed by EN-298.
