DSC HU/CM REMOVAL/INSTALLATION

CAUTIONWhen replacing the DSC HU/CM, the configuration procedure must be done before removing the DSC HU/CM. If the configuration is not completed before removing the DSC HU/CM, DSC will not work properly after installation of the DSC HU/CM. The internal parts of the DSC HU/CM could be damaged if dropped. Be careful not to drop the DSC HU/CM. Replace the DSC HU/CM if it is subjected to an impact.
